a=Distance from the molded line of second deck to upper edge of tonnage mark. d=Molded draft to upper edge of tonnage mark.

e=Freeboard from loadline certificate. h=Molded draft to loadline.

k=Distance from centerline of loadline disk to apex of triangle on tonnage mark. m=Distance from deck line to tonnage mark. t Distance from molded line of second deck to deck line for freeboard.

§ 2.92 Depth (D) used with the tonnage mark table.

(a) The depth (D,) to be used with the tonnage mark table in § 2.95 shall be the molded depth to the second deck.

(b) If the second deck is stepped, an equivalent depth shall be used. (See fig. 57.)

(1) If the higher portion of the deck is less than one-half the total length (L) of both portions, the depth for the table (D) shall be the molded depth amidships (D) increased by the ratio of the length of the shorter portion (I) to the total length (L) times the height of the step (b).

(2) If the lower portion of the deck is less than one-half the total length (L) of both portions, the depth for the table (D ̧) shall be the molded depth amidships (D) decreased by the ratio of the length of the shorter portion (I) to the total length (L) times the height of the step (b).

(D ̧=D——b in the lower example in

§ 2.93 Length (L) used in the tonnage mark table.

(a) The length (L) as used in the tonnage mark table shall be the distance on the second deck between two points, of which the foremost is the point where the underside of that deck or the line thereof at the stem, meets the inner surface of the ceiling, sparring or frames, and the aftermost is the point where the underside of that deck, or the line thereof, meets the inner surface of the ceiling, sparring or frames in the middle plane at the stern.

No line of the second deck shall be marked on the side of the vessel.

§ 2.97 Line of the uppermost complete deck.

(a) For a vessel having no statutory loadline, the line of the uppermost complete deck shall be marked similarly to the deck line provided by the Load Line Convention.

(b) The deck line shall be a horizontal line 12 inches long and 1 inch wide. It shall be marked abaft amidships above the place on each side of the vessel prescribed in § 2.90 for the tonnage mark. Its upper edge shall pass through the point where the continuation outward of the upper surface of the freeboard deck intersects the outer surface of the shell. (See fig. 58.) Where the deck is partly sheathed amidships, the upper edge of the deck line shall pass through the point where the continuation outward of the upper surface of the actual sheathing at amidships intersects the outer surface of the shell.

§ 2.98 Placing the tonnage mark in relation to the deck line.

(a) As a practical matter, since the molded line of the second deck is not to be marked on the side of the vessel, the position of the tonnage mark shall be determined by reference to the deck line

for freeboard or, in the absence of such a line, with reference to the deck line provided by § 2.97.

(b) The upper edge of the tonnage mark shall be below the upper edge of the deck line, a distance equivalent to the sum of the vertical distance (determined by reference to the tonnage mark table) from the molded line of the second deck or equivalent to the upper edge of the tonnage mark plus the vertical distance from the molded line of the second deck or equivalent to the upper edge of the deck line. (See in figs. 55 and 56, a+t=m.)

(c) In the case of a vessel for which it is desired to have only one set of tonnages, the tonnage mark shall be placed at the level of the uppermost part of the loadline grid as provided by § 2.91(b). (See fig. 56.)

§ 2.99 Application for measurement according to the optional dual-tonnage method.

(a) Application of the owner or his agent for measurement of a vessel under the provisions of the optional dual tonnage method shall be submitted in duplicate together with supporting plans or sketches to the customs officer in charge of the district in which the vessel is or I will be located.

(b) The application shall include the following information: (See figures 55, 56, and 57.)

(1) Molded depth at midship section from second deck at side.

(2) Depth used with tonnage mark table.

(3) Length of shorter portion of stepped second deck if any.

(4) Total length of longer and shorter portions of stepped second deck.

(5) Length used with tonnage mark table.

(6) Height of step (break) in the second deck, if any.

(7) Distance from the molded line of the second deck or equivalent to the upper edge of the tonnage mark.

(8) Molded draft to the upper edge of the tonnage mark.

(9) Freeboard from the loadline certificate.

(10) Molded draft to the loadline. (11) Horizontal distance from the centerline of the loadline disk to the apex of the triangle on the tonnage mark.

(12) Vertical distance from the deck line to the tonnage mark.

(13) Vertical distance from the molded line of the second deck or equivalent to the deck line for freeboard.

(14) Allowance for fresh water and tropical waters (148 of the molded draft to the upper edge of the tonnage mark). (15) The name and official number of the vessel, if assigned.

(16) Builder's name and hull number if official number has not been assigned. (17) Time and place vessel will be available for measurement.

(18) Whether two sets of tonnages are desired.

(c) The owner may request confirmation of the proposed location of the tonnage mark based on the information contained in the application.

(d) On a copy of the application or on an attachment thereto, the owner shall be advised:

(1) That the vessel will be measured under the provisions of the optional dual-tonnage method; and

(2) Whether the proposed location of the tonnage mark determined according to the information furnished on the application is correct under the provisions of the regulations.
