RULES FOR THE MEASUREMENT OF VESSELS FOR THE PANAMA
CANAL.

ARTICLE I. All vessels, American and foreign, except warships, including toag vessels to pese
tonnage document at
vessels of commerce and Army and Navy transports, colliers, supply ships, and canal.
hospital ships, applying for passage through the Panama Canal shall present
a duly authenticated certificate stating the vessel's gross and net tonnage as
determined by these rules. Vessels of commerce, Army and Navy transports,
colliers, supply ships, and hospital ships without such certificate shall, before
passing through the canal, or before being allowed to clear therefrom, be
measured, and shall have their gross and net tonnage determined in accord-
ance with these rules.
All warships, American and foreign, other than transports, colliers, supply
and hospital ships, shall present duly authenticated displacement scale and
curves stating accurately the tonnage of displacement at each possible mean
draft.
It is to be understood that "supply ships" shall include Army and Navv vessels designated as
."supply ships" and
ammunition ships, refrigerator ships, distilling ships, repair ships, submarine colliers. "
tenders, and destroyer tenders, as well as Army and Navy vessels used to
transport general Army and Navy supplies; and that "colliers" shall include
Army and Navy vessels used to transport coal or fuel oil.

RULES APPLYING TO VESSELS OF COMMERCE, ARMY AND NAVY TRANSPORTS,
COLLIERS, SUPPLY SHIPS, AND HOSPITAL SHIPS.
GROSS TONNAGE.

ART. II. Gross tonnage as determined by these rules shall express the. What shall be in-
total capacity of vessels, i. e., the exact cubical contents of all spaces below
the upper deck and of all permanently covered and closed-in spaces on or above
that deck, excepting such spaces as may be hereinafter permitted as exemptions
from measurement. Gross tonnage shall include not only all permanently
covered and closed-in spaces which are or may be used for stowing cargo and
stores or for providing shelter and other comfort for passengers or crew, but also
such spaces as are used, or are intended to be used, in navigating and serving
the vessel.
Only such spaces as are specifically mentioned in Article IV, below, shall
be exempted from measurement. All other spaces shall be considered as closed-
in and shall be included in gross tonnage.
ART. III. By permanently covered and closed-in spaces on or above the what shall be con-
sidered permanently
upper deck are to be understood all those which are separated off by decks covered and closed-in
spaces.
or coverings, or fixed partitions, and which, therefore, represent an increase
of capacity that is or may be used for the stowage of cargo, or for the
berthing and accommodation of the passengers, the officers, or the crew. No
break in a deck, nor any opening or openings in a deck or the covering of a
space or in the partitions or walls of a space, nor the absence of a partition
shall prevent a space from being measured and comprised in gross tonnage if
the opening or openings in the deck, partition, or side wall can be closed in, or
if the absent partition can be put in place, after admeasurement and the spaces
thus closed in be thereby better fitted for the transport of goods or passengers.












MEASUREMENT OF VESSELS FOR PANAMA CANAL.


In the case of a vessel having a "trunk" or "turret", the deck forming the
covering of the trunk or turret shall be considered the upper deck, and all
spaces below that deck within the trunk or turret shall be considered as cov-
ered and closed-in. The space within the turret or trunk shall be measured
as are other between-deck spaces.
Spaces considered as ''permanently closed-in" and spaces permitted to be
exempted from measurement shall be determined solely by the provisions
contained in these rules, and not by any definitions or provisions contained
in the measurement rules or regulations of any country.
measemenandro ART. IV. The following spaces shall be exempted from measurement
tonnage. and shall not be included in the gross tonnage, and no other spaces shall be
exempted:
SECTION 1. Spaces on or above the upper deck not permanently covered
or closed-in, or which may not be readily covered or closed-in. In the appli-
cation of this rule it will be understood that-
(a) Spaces under decks or coverings having no other connection with the
body of the ship than the stanchions necessary for their support are not spaces
separated off, but are spaces permanently exposed to the weather and the sea
and are not to be included in the gross tonnage.
(b) A space within a poop, forecastle, bridge house, or other "permanently
covered and closed-in" superstructure or erection may be considered as not
permanently covered or closed-in, and may consequently be excluded from
tonnage, if the space is opposite an end opening which is without a coaming
and has no headplates or planks and is not provided with means of closing,
and which opening has a breadth equal to or greater than half the breadth of
the deck at the line of the opening, and if the space opposite the opening can
not be used to shelter other merchandise than cargo or stores that do not require
protection from the sea. If the opening is fitted with a coaming, the space
within it is to be included in the gross tonnage. This provision shall be so
applied as to exempt from measurement only the space between the actual
end opening and a line drawn parallel to the line or face of the opening at a
distance from the opening equal to one-half the width of the deck at the line
of the opening; provided, that any closed-in space between the open face and
the line drawn parallel to it shall be measured. The remainder of the space
within a poop, forecastle, bridge house, or other superstructure or erection shall
be considered as available for the accommodation of cargo or stores, of
passengers or of the ship's personnel, and shall be measured and included in
the gross tonnage. (See Figs. 1, 2, and 3.)
Should the open space within a poop, forecastle, bridge house, superstructure,
or erection between the end opening and a parallel line distant from the opening
by half the breadth of the deck become, because of any arrangement, of less
width than half the breadth of the deck, then only the space between the line
of the end opening and a parallel line drawn through the point where the
athwartship width of the open space within the poop, forecastle, bridge house,
superstructure, or erection becomes equal to, or less than, half the breadth of
the deck shall be exempted from measurement. (See Figs. 4, 5, 6, and 7.)
The remainder of the space within the poop, forecastle, bridge house, super-
structure, or erection is to be included in the gross tonnage.
When two erections extending from side to side of the ship are separated
by an interval the fore-and-aft length of which is less than the least half breadth
of the deck in way of such interval, then whatever be the breadth of the per-
manent end openings of the erections, the entire erections, less the interval
separating them, shall be measured and included in the gross tonnage. (See
Fig. 8.)

(c) In a poop, forecastle, side-to-side bridge house, or other "permanently
covered and closed-in" superstructure or side-to-side erection the space directly
in way of opposite openings, the height of which is at least 3 feet, in the side
walls of the ship not provided with means of closing and corresponding to each
other in the opposite walls of the ship shall be exempted. (See Figs. 9 and 10.)
SEC. 2. Spaces in way of opposite side openings at least 3 feet in height
not provided with means of closing shall be exempted. In the case of a con-
tinuous deck with one or more deck openings (usually designated as tonnage
openings) that may be so closed as to permit cargo or stores to be carried in
the space under the deck, or under portions thereof, only the spaces under such
a deck that are exactly in way of opposite openings at least 3 feet in height
in the side walls of the ship not provided with means of closing and correspond-
ing to each other in the opposite walls of the ship shall be exempted; and the
remaining spaces under such a deck shall be measured and included in gross
tonnage. In case the openings in the side walls of the ship are provided with
means of closing, no portion of the space under such a deck shall be exempted.
(Fig. 11.)
SEC. 3. The spaces framed in round the funnels and the spaces required for
the admission of light and air into the engine rooms shall be exempted from
measurement to the extent that such spaces are above the deck or covering
of the first or lowest tier of side-to-side erections, if any, on the upper deck.
A deck with one or more deck openings (usually designated as tonnage open-
ings) that may be so closed as to permit cargo or stores to be carried in the
space under the deck or portions thereof is to be considered as the upper deck,
provided that no space beneath it abreast side openings is exempted under the
provisions of section 2. There shall, however, be measured and included
within gross tonnage the spaces situated within closed-in side-to-side erections
on the upper deck, spaces framed in round the funnels and those required for
the admission of light and air to the extent that such light and air and funnel
spaces are below the deck or covering of the first or lowest tier of such side-
to-side erections on the upper deck. There shall be exempted from the measure-
ment of any superstructure or erection situated above the first or lowest tier
of side-to-side erections on the upper deck such portion or portions thereof as
are occupied by the spaces framed in round the funnels or by the spaces
required for the admission of light and air into the engine rooms. Such
exempted spaces must not be used for any other than their designated purpose
and must be reasonable in extent.
SEC. 4. Space or spaces between the inner and outer plating of the double
bottom of a vessel that are so inclosed and that have such openings as to make
them usable only for water ballast shall be exempted from measurement; but
such spaces within the double bottom as are or may be used for carrying cargo,
stores, feed water, coal, or other fuel shall be measured and included in the
gross tonnage.
SEC. 5. The cubical contents of hatchways shall be obtained by multi-
plying the length and breadth together and the product by the mean depth
taken from the top of beam to the underside of the hatch. From the aggregate
tonnage of the hatchways there shall be deducted one-half of 1 per cent of the
vessel's gross tonnage, exclusive of hatchways, and only the remainder shall be
added to the gross tonnage of the ship, exclusive of the tonnage of the hatchways.
SEC. 6. Companionways and companion houses shall be exempted when
used solely as companionways or companion houses. When used as smoking
rooms or for any other purposes than companionways or companion houses,
the parts so used shall be measured and included in gross tonnage.

SEC. 7. Domes and skylights shall be exempt from measurement. When
there is an opening in the floor of a superstructure immediately below a skylight,
the exemption shall include the space between the skylight and the opening in
the floor of the superstructure immediately under the skylight. The remainder
of the superstructure shall be included in the measurement. The space, in
addition to the skylight, that may be exempted by this rule is that indicated by
A, B, C, D in the following drawing:

exempted space, except spaces exempted under Art. IV, Sec. 1, Par. (b) and
spaces on open decks not permanently covered, or upon decks as defined
in Art. IV, Sec. 1, Par. (a), of these rules, the whole of that space shall be
measured and added to the gross tonnage, and the space shall not thereafter
be exempted from measurement.

In case of Army and Navy transports, colliers, supply ships, and hospital
ships as defined in Article I, the term "passengers" shall include all officers,
enlisted men, and other persons who are not assigned to duty and who are
not duly inscribed on the ship's rolls.

net tonnage (as defined below in Articles X and XII) increased by the tonnage
of the space occupied (at the time at which the tolls or other charges become
payable) by the goods carried upon deck and not permanently covered or
closed-in. The deck space occupied by the goods thus carried shall be deter-
mined at the time of the application of the vessel for passage through the
canal and shall be deemed to be the space limited by the area occupied by the
goods and by straight lines inclosing a rectangular space sufficient to include
the goods. The tonnage of the space occupied by the goods shall be ascertained
in the manner prescribed below by Article IX, Rule I, for the measurement of
poops or other closed-in spaces.
Nothing in this article shall in any manner affect the provisions of Articles
II, III, and IV.

ART. IX. In countries that have'not adopted the Moorsom system of ment'of contents of
measuring spaces within vessels, the cubical contents of any of the spaces spaces.
included in gross tonnage shall be ascertained according to the Moorsom system
as set forth in the following rules: Rule I for the measurement of empty
vessels; Rule II for laden vessels; Rule III for open vessels.
RULE I.-For measuring the gross tonnage of empty vessels. Rme for the measure
ment of empty vessels.
SECTION 1. The length for the admeasurement of ships having one or
more decks is taken on the tonnage deck, which is-
(a) The upper deck for vessels having one or two decks.
(b) The second deck from below for vessels having more than two decks.
Measure the length of the ship in a straight line along the upper side of the
tonnage deck from the inside of the inner plank (average thickness) at the side
of the stem to the inside of the midship stern timber or plank there, as the case
may be (average thickness), deducting from this length what is due to the
rake of the bow in the thickness of the deck and what is due to the rake
of the stern timber in the thickness of the deck, and also what is due to the rake
of the stern timber in one-third of the round of the beam; divide the length so
taken into the number of equal parts required by the following table, according
to the class in such table to which the ship belongs:
Class 1: Ships of which the tonnage deck is, according to the above measure-
ment, 50 feet long or under, into 4 equal parts.
Class 2: Ships of which the tonnage deck is, according to the above measure-
ment, above 50 feet long and not exceeding 120 feet, into 6 equal parts.
Class 3: Ships of which the tonnage deck is, according to the above measure-
ment, above 120 feet long and not exceeding 180 feet, into 8 equal parts.
Class 4: Ships of which the tonnage deck is, according to the above measure-
ment, above 180 feet long and not exceeding 225 feet, into 10 equal parts.
Class 5: Ships of which the tonnage deck is, according to the above measure-
ment, above 225 feet long, into 12 equal parts.'
In the case of a break or breaks in a double-bottom for water ballast, the
length of the vessel is to be taken in parts according to the number of breaks,
and each part divided into a number of equal parts according to the class in
the above table to which such length belongs.
SEC. 2. Then the hold being first sufficiently cleared to admit of the
required depths and breadths being properly taken, find the transverse area of
the ship at each point of division of the length or each point of division of the
parts of the length, as the case may require as follows: Measure the depth at
each point of division, from a point at a distance of one-third of the round of
the beam below the tonnage deck, or, in case of a break, below a line stretched
in continuation thereof, to the upper side of the floor timber (upper side of the
inner plating of the double bottom) at the inside of the limber strake, after
deducting the average thickness of the ceiling which is between the bilge
planks and the limber strake, subject, however, to the provisions of these rules,
Article IV, section 4, regarding the measurement or exemption of double-
bottom spaces. In the case of a ship constructed with a double-bottom for
water ballast if the space between the inner and outer plating thereof is not
available for the carriage of cargo, stores, feed-water, coal, or other fuel, then
the depth shall be taken to be the upper side of the inner plating of the double-
bottom, and that upper side shall, for the purposes of measurement, be deemed
to represent the floor timber.of the vessel. This rule for measuring the depth
of the hold applies to double-bottom ships having top of double bottom not
horizontal.


I A greater number of divisions is permissible provided there be an even number of divisions.











MEASUREMENT OF VESSELS FOR PANAMA CANAL.


If the depth at the midship division of the length does not exceed 16 feet,
divide each depth into 5 equal parts; then measure the inside horizontal
breadth at each of the four points of division, and also at the upper point of
the depth, extending each measurement to the average thickness in that
part of the ceiling which is between the points of measurement. Number
these breadths from above (i. e., numbering the upper breadth 1, and so on
down to the fifth breadth); multiply the second and fourth by 4, and the
third by 2; add these products together, and to the sum add the first breadth
and the fifth. Multiply the quantity thus obtained by one-third of the common
interval between the breadths, and the product shall be deemed the trans-
verse area of the upper part of the section; then find the area between the
fifth and lower point of the depth by dividing the depth between such points
into four equal parts, and measure the horizontal breadths at the three points
of division and also at the upper and lower points, and proceed as before, and
the sum of two parts shall be deemed to be the transverse area; but if the
midship depth exceed 16 feet, divide each depth into 7 equal parts instead
of 5, and measure, as before directed, the horizontal breadths at the six
points of division, and also at the upper point of the depth; number them from
above, as before; multiply the second, fourth, and sixth by 4, and the third and
fifth by 2; add these products together, and to the sum add the first breadth
and the seventh. Multiply the quantity thus obtained by one-third of the
common interval between the breadths, and the products shall be deemed the
transverse area of the upper part of the section; then find the lower part of
the area as before directed, and add the two parts together, and the sum shall
be deemed to be the transverse area.
This section applies to vessels with double bottoms, the tops of which have
a rise from the middle line to each side. In vessels in which the top of the
double bottom is horizontal, or in which there is no double bottom, the depths
are to be divided by 4 or 6 (instead of 5 or 7), according as their midship
depths do not or do exceed 16 feet respectively. In such cases no subdivision
of the lower part is to be made.
SEC. 3. Number the transverse sections or areas respectively 1, 2, 3, etc.,
No. 1 being at the extreme limit of the length at the bow, or of each part of the
length, and the last number at the extreme limit of the length at the stern or
the extreme limit at the after end of each part of the length; then, whether
the length be divided according to the table into 4 or 12 parts, as in classes 1
and 5, or any intermediate number, as in classes 2, 3, and 4, multiply the second
and every even-numbered area by 4, and the third and every odd-numbered
area (except the first and last) by 2; add these products together, and to the
sum add the first and last, if they yield anything; multiply the quantity thus
obtained by one-third of the common interval between the areas, and the product
will be the cubical contents of the space, or cubical contents of each part if the
ship is measured in parts under the tonnage deck. The tonnage of this volume
is obtained by dividing it by 100, if the measurements are taken in English
feet, and by 2.83 if the measurements are taken in meters. The multiplier
0.353 may be used instead of the divisor 2.83.
SEC. 4. If the ship has a third deck the tonnage of the space between it and
the tonnage deck shall be ascertained as follows: Measure in feet the
inside length of the space at the middle of its height from the plank at the
side of the stem to the lining on the timbers at the stern, and divide the length
into the same number of equal parts into which the length of the tonnage deck
is divided, as above directed; measure (also at the middle of its height) the
inside breadth of the space at each of the points of division, also the breadth at












MEASUREMENT OF VESSELS FOR PANAMA CANAL.


the stem and the breadth at the stern; number them successively 1, 2, 3, etc.,
commencing at the.stem; multiply the second and all the other even-numbered
breadths by 4, and the third and all the other odd-numbered breadths (except
the first and last) by 2; to the sum of these products add the first and last
breadths; multiply the whole sum by one-third of the common interval between
the breadths, and the result will give in superficial feet the mean horizontal area
of the space; measure the mean height of the space, and multiply by it the mean
horizontal area, and the product will be the cubical contents of the space; divide
this product by 100 (or by 2.83 if the measurements are taken in meters) and
the quotient shall be deemed to be the tonnage of the space, and shall be added
to the tonnage of the ship ascertained as aforesaid; and if the ship has more than
three decks, the tonnage of each space between decks above the tonnage deck
shall be severally ascertained in the manner above described, and shall be added
to the tonnage of the ship ascertained as aforesaid.
SEC. 5. If there be a break, a poop, or any other permanently covered or
closed-in space on or above the upper deck (as defined above in Article III)
the tonnage of such space shall be ascertained as follows: Measure the internal
mean length of the space in feet, and divide it into two equal parts; measure at
the middle of its height three inside breadths, namely, one at each end and the
other at the middle of the length; then to the sum of the end breadths add four
times the middle breadth, and multiply the whole sum by one-third of the
common interval between the breadths; the product will give the mean hori-
zontal area of the space; then measure the mean height and multiply by it
the mean horizontal area; divide the product by 100 (or by 2.83 if the measure-
ments are taken in meters) and the quotient shall be deemed to be the tonnage
of the space.
SEC. 6. In measuring the length, breadth, and height of the general volume
of the ship or that of the other spaces, reduce to the mean thickness the parts
of the ceiling which exceed the mean thickness. When the ceiling is absent,
or when it is not permanently fixed, the length and breadth shall be reckoned
from the main frames of the ship, not from the web or belt frames. The same
principle is to hold in the case of deck erections, that is, the breadth is to be
reckoned from the main framing or stiffeners of the same, when ceiling
is not fitted. When the main framing of the ship is curved or carried
upward and inboard so as to permit the building of topside tanks or compart-
ments outboard of the main framing, the breadth of the ship shall be
reckoned from the outboard framing of such outboard tanks, thus including
these tanks in the measurement.
RULE II.-For measuring the gross tonnage of laden ships.

SEC. 7. When ships have cargo on board, or when for any other reason Rule for the measure-
ment of ladda vessels.
their tonnage can not be ascertained by means of Rule I, proceed in the fol-
lowing manner:
Measure the length on the uppermost full-length deck from the outside
of the outer plank at the stem to the aft side of the sternpost, deducting there-
from the distance between the aft side of the sternpost and the rabbet of the
sternpost at the point where the counterplank crosses it. Measure also the
greatest breadth of the ship to the outside of the outer planking or wales
at the middle perpendicular. Then, having first marked on the outside of the
ship on both sides thereof the height of the uppermost full-length deck at the
ship's sides, girt the ship at the middle perpendicular in a direction perpen-
dicular to the keel from the height so marked on the outside of the ship, on
the one side, to the height so marked on the other side, by passing a chain under












MEASUREMENT OF VESSELS FOR PANAMA CANAL.


the keel; to half the girth thus taken add half the main breadth; square the sum,
multiply the result by the length of the ship taken as aforesaid, then multiply

factor 0.18 in the case of ships built of iron or steel. The product will give
approximately the cubical contents of the ship, and the tonnage can be ascer-
tained by dividing by 100 or by 2.83, according as the measurements are taken
in English feet or in meters.
SEC. 8. If there be a break, a poop, or other permanently covered and closed-
in spaces (as defined above in Article III) on or above the uppermost full-
length deck, the tonnage of such spaces shall be ascertained by multiplying
together the mean inside length, breadth, and depth of such spaces and dividing
the product by 100, or 2.83, according as the measurements are taken in English
feet or meters, and the quotient so obtained shall be deemed to be the tonnage
of the spaces, and shall be added to the other tonnage in order to determine
the gross tonnage or total capacity of the ship.

RULE III.-For measurement of open vessels.

meant of open vessels- SEC. 9. In ascertaining the tonnage of open ships, the upper edge of the
upper strake of the shell plating is to form the boundary line of measurement,
and the depths shall be taken from an athwartship line, extended from upper
edge to upper edge of the said strake at each division of the length.

DEDUCTIONS FROM THE GROSS TONNAGE TO ASCERTAIN THE NET TONNAGE.
(A) DEDUCTIONS FOR VESSELS NOT PROPELLED BY ENGINES.

ART. X. The following spaces (enumerated below in secs. 1 to 10 of this
article) shall be deducted from the gross tonnage in order to ascertain the
net tonnage of vessels not propelled by engines, and no other spaces shall be
deducted. Unless otherwise expressly stipulated, these spaces shall be deducted
whether located above or below the upper deck.
The volume or cubical contents of deducted spaces shall be ascertained in
the manner specified in Article VIII or Article IX of these rules. The remainder,
resulting from deducting from the total space included in gross tonnage the
sum of the cubical contents of the spaces whose deduction from gross tonnage
is permitted by these rules, shall be the net or register tonnage of vessels not
propelled by engines and unrigged craft upon which tolls and other charges
based upon tonnage shall be paid by vessels of commerce, Army and Navy
transports, colliers, supply ships, and hospital ships (as defined in Art. I) for
passage through the Panama Canal. One hundred cubic feet, or 2.83 cubic
meters, shall constitute one gross or net ton.
Spaces for the use, or possible use, of passengers (as defined in Art. VI)
shall not be deducted from the gross tonnage, except in so far as their deduc-
tion may be specifically provided for in the following sections (1 to 10) of this
article of these rules.
ande o"ncaieodo Spaces available for the stowage of stores (other than boatswain's stores) or
ort, "cliers, suy cargo shall not be deducted from gross tonnage. In case of Army and Navy
ships and hospital transports, colliers, supply ships, and hospital ships, as defined in Article I,
the term "stores (other than boatswain's stores) or cargo" shall include, in
addition to goods or cargo ordinarily carried as freight on vessels of commerce,
the following articles:
On transports, food, stores, luggage, accouterments, and equipment for
passengers.
On colliers, coal, coaling gear, and fuel oil not for the use of the colliers.

On supply ships, stores, supplies of all kinds, distilling machinery and dis-
tilled water (other than feed water stored in double-bottom compartments),
machines, tools and material for repair work, mines and mining material, tor-
pedoes, arms, and ammunition.
On hospital ships, food stores for passengers, medical stores, and hospital
equipment.
Guns mounted on transports and supply ships, for defense of the ships,
and ammunition required for use in such guns shall not be classed as cargo.
SECTION 1. The tonnage of the spaces or compartments occupied by, or tonnage allowed vessels
appropriated to the use of, the officers and crew of the vessel shall be deducted. ges.ro'pe"ed by en-
The term "officers and crew" shall include the personnel inscribed on the ship's
rolls, i. e., the ship's officers, engineers, doctors, apothecary, sick attendants,
sailors, apprentices, firemen, mechanics, and wireless operators; but shall not
include clerks, pursers, stewards, and other members of the personnel provided
by the ship for the care of the passengers. The spaces or compartments
occupied by the officers and crew shall include their berthing accommoda-
tions, spaces provided for medical attention, mess rooms, ward and dressing
rooms, bath and wash rooms, water-closets, latrines, lavatories, or privies for
their exclusive use, and passageways exclusively serving these spaces.
SEC. 2. On hospital ships the spaces or compartments occupied by doctors,
apothecary, and sick attendants duly inscribed on the ship's rolls, shall form
part of the deduction under section 1 of this article. Spaces provided for the
medical attention of the officers and crew of a hospital ship shall likewise be
deducted; but spaces fitted for the transportation, or for the medical attention,
of other persons than those duly listed in the ship's rolls shall not be deducted.
SEC. 3. The space occupied by the master's cabin shall be deducted.
SEC. 4. Cook houses, galleys, bakeries, laundries, and rooms for ice
machines, when used exclusively to serve the officers and crew, and the con-
denser space, and distilling rooms, when used exclusively for condensing and
distilling the water for the officers and crew, shall be deducted.
SEC. 5. Spaces used for the anchor gear, steering gear, and capstan; the
wheel house, the dynamo rooms; the chart room used exclusively for keeping
charts, signals, and other instruments of navigation; lookout houses; spaces
for keeping electric searchlights and wireless telegraph appliances; and other
spaces actually used in the navigation of the ship, shall be deducted. Such
spaces upon vessels of commerce as may be devoted to the mounting of guns
and to the stowage of ammunition for the guns thus mounted shall be
deducted. The deduction of all spaces, other than those devoted to the
mounting of guns, enumerated in this section must be reasonable in extent
and be subject to the limitations stipulated below in Article XI.
SEC. 6. In case of a ship propelled wholly by sails, any space, not exceed-
ing 21 per cent of the gross tonnage, used exclusively for storage of sails shall
be deducted.
SEC. 7. Spaces used exclusively for boatswain's stores shall be deducted.
The deduction is not, however, to exceed 1 per cent of the gross tonnage in
ships of 1,000 tons gross and upwards, nor more than 75 tons in any ship
however large. In vessels from 500 to 1,000 tons gross the limit is fixed at
10 tons and in vessels from 150 to 500 tons at not more than 2 per cent of the
gross tonnage. In vessels under 150 tons at not more than 3 tons.
SEC. 8. The space occupied by donkey engine and boiler shall be deducted
if the donkey engine and boiler are connected with the main pumps of the
ship, or if they are located in a permanently covered or closed-in structure on
or above the upper deck.
SEC. 9. Passages and passageways shall be deducted if they serve deducted
spaces exclusively for the officers and crew.

SEC. 10. Water-ballast spaces, other than spaces in the vessel's double
bottom, shall be deducted if they are adapted only for water ballast, have only
ordinary manholes for access and are not available for the carriage of cargo,
stores, or fuel. If used to carry oil or other fuel, these spaces shall be regarded
as part of the vessel's fuel space and shall not be subject to separate deduction.

use of exempted spaces
all be according to otherwise specifically stated, shall be subject to such conditions and require-
ments as to marking or designation and use or purpose as are contained in the
navigation or registry laws of the several countries, but no space, other than fuel
spaces deducted under Article XIII of these rules, shall be deducted unless
the use to which it is to be exclusively devoted has been appropriately desig-
nated by official marking. In no case, however, shall an arbitrary maximum
limit be fixed to the aggregate deduction made under Article X.
(B) DEDUCTIONS FOR VESSELS PROPELLED BY ENGINES.

ART. XII. The net or register tonnage upon which tolls and other charges
based upon tonnage shall be paid by vessels of commerce, Army and Navy
transports, colliers, supply ships, and hospital ships, as defined in Article I, pro-
pelled by engines, for passage through the Panama Canal, shall be the tonnage
remaining after the following deductions have been made from the gross tonnage.
One hundred cubic feet, or 2.83 cubic meters, shall constitute 1 gross or net
ton. Vessels propelled partly by sails and partly by engines shall be classed as
"vessels propelled by engines:"
Deductions from gross SECTION 1. The spaces specified above in Article X shall be deducted from
tonnage allowed vessels
propelled by engines, the space included in gross tonnage to ascertain net tonnage in the case of
vessels propelled by engines as in the case of vessels not propelled by engines.
SEC. 2. The space occupied by the engines, boilers, coal bunkers, fuel-oil
tanks, double-bottom fuel and feed-water compartments, shaft trunks of vessels
with screw propellers, spaces, within a closed-in side-to-side erection, that are
framed in around the funnels or that are required for the introduction of light
and air to the engine room to the extent that the framed-in spaces around the
funnels and the light and air casings are located below the deck or covering
of the first or lowest tier of such erections, if any, on the upper deck, as defined
in Article IV, section 3, and are contained in closed-in side-to-side erections,
spaces necessary for the proper working of the engines, and spaces occupied by
the donkey engine and boiler when situated within the boundary of the engine
room or within the light and air casings above the engine room and when used
in connection with the main machinery for propelling the vessel. When the
shafts of screw propellers pass through open spaces not inclosed within tun-
nels, the spaces allowed in lieu of the tunnels must be of reasonable dimen-
sions suitable for the vessel in question. When any portion of the engine or
boiler rooms is occupied by a tank for fresh water, the space thus taken up
shall not be deducted.
Donkey-engine and boiler spaces, when deducted according to Article
XIV below, shall not be made a separate deduction.
The portion of the framed-in spaces around the funnels and of the light
and air casings that extend above the deck or covering of the first or lowest
tier of side-to-side erections, if any, on the upper deck, as defined in Article
IV, section 3, and surrounding the said space or spaces are exempted from
measurement and form no part of the space deducted under this section.
SEC. 3. The deductions made for propelling power, including all those
provided for in section 2.of this article, shall in no case exceed 50 per cent of
the gross tonnage, except in case of tugs employed exclusively as tugs. In

other respects the spaces enumerated in section 2 shall, except as otherwise
specifically stated, be subject to the requirements as to designation or marking
and use or purpose contained in the navigation or registry laws of the several
countries.
SEC. 4. The deductions made for propelling power provided for in section 2
of this article shall be made according to the provisions of Article XIII or of
Article XIV, as the owner of the vessel may elect.
SEC. 5. Double-bottom compartments that are set aside to be used exclu-
sively for the stowage of feed water for the ship's boilers shall be deducted.
ART. XIII. In ships that do not have fixed bunkers, but transverse dutofor vesselswith
bunkers with movable partitions, with or without lateral bunkers, and in ships Iukes hvig mo

to it for vessels with screw propellers 75 per cent and for vessels with paddle
wheels 50 per cent of such space.
By the space occupied by the engine rooms is to be understood that
occupied by the engine room itself and the boiler room, together with the spaces
strictly required for the working of the engines and boilers, with the addition of
the spaces taken up by shaft trunks (in vessels with screw propellers), the spaces
which inclose the funnels and the casings necessary for the admission of light
and air into the engine room to the extent that such spaces are located below
the upper deck or below a deck with openings (usually designated as tonnage
openings) which may be so closed as to permit the carriage of cargo or stores
under the deck or a portion thereof, and donkey-engine and boiler spaces when
the donkey engine and boiler are situated within the boundary of the main
engine room or of the light and air casing above it and when they are used in
connection with the main machinery for propelling the vessel. When the
shafts of screw propellers pass through open spaces not inclosed within tun-
nels, the spaces allowed in lieu of tunnels must be of reasonable dimensions
suitable for the vessel in question. When a portion of the space within the
boundary of the engine or boiler rooms is occupied by a tank or tanks for fuel
oil or fresh water, the space considered to be within the engine room shall be
reduced by the space taken up by the tank or tanks for fuel oil or fresh water.
The cubical contents of the above-named spaces occupied by the engine
room shall be ascertained in the following manner: Measure the mean depth
of the space occupied by the engines and boilers from its crown to the ceiling
at the limber strake; measure also three, or, if necessary, more than three,
breadths of the space at the middle of its depth, taking one of such measure-
ments at each end and another at the middle of the length; take the mean of
such breadths; measure also the mean length of the space between the fore-
most and aftermost bulkheads or limits of its length, excluding such parts, if
any, as are not actually occupied by or required for the proper working of the
engines and boilers. Multiply together these three dimensions of length,
breadth, and depth, and the product will be the cubical contents of the space
below the crown. Then, by multiplying together the length, breadth, and
depth, find the cubical contents of the space or spaces, if any, which are framed
in for the machinery, for inclosing the funnels, or for the admission of light and
air, and which are located between the crown of the engine room and the upper-
most deck or covering of the first or lowest tier of side-to-side erections, if any,
on the upper deck, as defined in Art. IV, section 3. Add such contents, as
well as those of the space occupied by the shaft trunk and by any donkey
engine and boiler located within the boundary of the engine room or of the light
and air casing above the engine room and used in connection with the main











MEASUREMENT OF VESSELS FOR PANAMA CANAL.


engines for propelling the ship, to the cubical contents of the space below the
crown of the engine room; divide the sum by 100 or by 2.83, according as the
measurements are taken in feet or meters, and the result shall be deemed to be
the tonnage of the engine and boiler room and shall be the tonnage taken as
the basis for calculating the deduction for propelling power.
If in any ship in which the space for propelling power is to be measured
the engines and boilers are in separate compartments, the contents of each
compartment shall be measured separately in like manner, according to the
above method; and the sum of the tonnage of the spaces included in the
several compartments shall be deemed to be the tonnage of the engine and
boiler rooms, and shall be the tonnage taken as the basis for calculating the
deduction for propelling power.
lPropeling power de ART. XIV. When vessels are fitted with fixed coal bunkers or with fuel-oil
r"l-ei"u cormpartnent'i tanks or double-bottom fuel compartments which can not be used to stow
stow cango or s to cargo or stores, and when such bunkers, tanks, and fuel compartments have
been certified by official marking to be spaces for the vessel's fuel, the deduc-
tion for propelling power may either be in accordance with the provisions of
Article XIII above, or by deducting the actual tonnage of the spaces enu-
merated in Art. XII, Sec. 2 as measured in accordance with the following
provisions, as the owner of the vessel may elect: Measure the mean length of
the engine and boiler room, including the coal bunkers. Ascertain the area of
three transverse sections of the ship (as set forth in the rules given in Articles
VIII or IX for the calculation of the gross tonnage) to the deck which covers
the engine. One of these three sections must pass through the middle of the
aforesaid length, and the two others through the two extremities. Add to the
sum of the two extreme sections four times the middle one, and multiply the
sum thus obtained by the third of the distance between the sections. This
product divided by 100 if the measurements are taken in English feet, or by
2.83 if they are taken in meters, gives the tonnage of the space measured.
If the engines, boilers, and bunkers are in separate compartments, measure
each compartment, as above set forth, and add together the results of the
several measurements. The bunkers measured for fuel deduction shall include
only those bunkers that are absolutely permanent, from which the coal can be
trimmed directly into the engine room or stokehole, and into which access can
be obtained only through the ordinary coal chutes on deck and from doors
opening into the engine room or stokehole. Thwartship bunkers that can be
in any way extended are not to be included in the measurements for deduc-
tions. When any portion of the engine or boiler rooms is occupied by a tank
for fresh water, the space considered to be within the engine and boiler rooms
shall be reduced by the space taken up by the tank for fresh water.
The contents of the shaft trunk shall be measured by ascertaining, and
multiplying together, the mean length, breadth, and height. The product
divided by 100, or 2.83, according as the measurements are taken in English
feet or in meters, gives the tonnage of such space. When the shafts of screw
propellers pass through open spaces not inclosed within tunnels, the spaces
allowed in lieu of tunnels must be of reasonable dimensions suitable for the
vessel in question.
The tonnage of the following spaces below the deck or covering of the first
or lowest tier of side-to-side erections, if any, on the upper deck, as defined
by Art. IV, section 3, is ascertained by the same method, viz: (a) The spaces
framed in around the funnels. (b) The spaces required for the admission of
light and air into the engine room. (c) The spaces, if any, necessary for the
proper working of the engines. (d) Spaces occupied by the donkey engine and
