(b) The Commissioner of Customs shall, in the following sections, be referred to as the Commissioner.

(c) Doubts arising in the minds of the admeasures concerning decks to the hull, enclosures on or above the upper deck, shelter decks, method of procedure, etc., shall be submitted to the Commissioner for his decision, and shall be accompanied by blueprints or sketches of the spaces in question giving all the facts bearing on same.

[28 F.R. 14553, Dec. 31, 1963, as amended by T.D. 66-57, 31 F.R. 4294, Mar. 11, 1966] § 2.2

What vessels are to be admeasured. (a) Before any vessel is registered, enrolled and licensed, or licensed, or issued a certificate of record, her tonnages shall be ascertained by an officer of the customs as provided in these regulations.

(b) In the discretion of the Commissioner of Customs, a vessel not required by law to be admeasured may nevertheless be admeasured upon his own motion or upon application by the owner, a Federal or State agency, or a foreign government.

[T.D. 67-69, 32 F.R. 3388, Mar. 1, 1967] § 2.3 Purpose for which measurements are taken.

§ 2.4 Register ton.

A register ton is a volume of 100 cubic feet.

§ 2.5 Gross register tonnage.

(a) The gross tonnage, referred to in this part is the gross register tonnage; that is, the gross tonnage exclusive of all permissible exempted spaces. Under the provisions of § 2.87(b), a vessel may have two gross tonnages. The higher gross tonnage is applicable when a tonnage mark which is placed and displayed on the side of the vessel is submerged and the lower is applicable when the tonnage mark is not submerged.

(b) Except in the case of a vessel which is measured under the provisions of $ 2.80 through 2.100, or under the provisions of §§ 2.101 through 2.104, the gross register tonnage of a vessel shall consist of the following items:

(1) The cubic capacity below the tonnage deck, excluding exemptible water-ballast spaces within the measurable portion of the vessel;

(2) The cubic capacity of each between-deck space above the tonnage deck;

(3) The cubic capacity of the permanent closed-in spaces on the upper deck available for cargo or stores, or for the accommodation of passengers and/or

crew;

(4) All permanent closed-in spaces situated elsewhere available for cargo or stores, or for the accommodation of the crew, or for the charts, except cabins or staterooms for passengers, constructed entirely above the first deck which is not a deck to the hull;

(5) The excess of hatchways.

(c) The gross tonnage of a vessel measured under the provisions of §§ 2.80 through 2.100 shall be determined as provided by § 2.86(a).

(d) The gross tonnage of a vessel measured under the provisions of §§ 2.101 through 2.104 shall be determined as provided by § 2.103.

[T.D. 66-57, 31 F.R. 4294, Mar. 11, 1966, as amended by T.D. 67-69, 32 F.R. 3388, Mar. 1, 1967]

(a) The tonnage of a vessel remaining after the authorized deductions have

been made from the gross register tonnage shall be deemed the net register tonnage. Under the provisions of 2.87 (b) a vessel may have two net tonnages.

(b) In ascertaining the net tonnage, no space may be deducted unless it has previously been included in the gross tonnage.

(c) The net tonnage of a vessel measured under the provisions of §§ 2.101 through 2.104 shall be determined as provided by § 2.104.

[28 F.R. 14553, Dec. 31, 1963, as amended by T.D. 66–57, 31 F.R. 4295, Mar. 11, 1966, T.D. 67-69, 32 F.R. 3389, Mar. 1, 1967]

(a) The marine document of every vessel except one admeasured under the provisions of §§ 2.101 through 2.104 shall show the date and place of build, the register length, breadth, depth, and the height of the upper deck to the hull above the tonnage deck; if applicable, the depth (D,) and the length (Lt) used with the tonnage mark table and the distances to the tonnage mark from the line of the upper deck and from the molded line or equivalent of the second deck; the number of decks and masts; build as to her stem and stern; capacity under the tonnage deck, that of the between decks, and also separately, permanently enclosed spaces on or above the upper deck to the hull required to be included in the gross tonnage, and the omitted spaces, whether open or closedin, on, above, or below the upper deck; the gross tonnage or tonnages; items of deduction; and the net tonnage or tonnages.

(b) The marine document of every vessel admeasured under the provisions of §§ 2.101 through 2.104 shall show the date and place of build, the register length, breadth, and depth, and the gross and net tonnages.

[T.D. 66-57, 31 F.R. 4295, Mar. 11, 1966, as amended by T.D. 67-69, 32 F.R. 3889, Mar. 1, 1967]

§ 2.8

Application for measurement. The builder of a new vessel which is to be admeasured, the person having supervision of changes or alterations, or both, affecting a vessel's register tonnage, and the owner of a vessel who elects to have her admeasured under the provisions of §§ 2.101 through 2.104 or who, having had the vessel so admeasured, elects or is required to have her admeasured under the appropriate provisions of §§ 2.11 through 2.100, shall apply in writing for admeasurement or tonnage adjustment, as the case may be, to the district director of customs for the district where the vessel is located. Except in the case of admeasurement under §§ 2.101 through 2.104, application should be made in time to permit admeasurement before cargo or ballast is taken on, and in case of a new vessel, before boilers or engines are installed or compartments partitioned off. The application shall state the name and the official number of the vessel, if any, the name, address, and telephone number of the owner, the exact location of the vessel, the date and place of build and the builder's name, the rig, and model or other identifying numbers. [T.D. 67-69, 32 F.R. 3389, Mar. 1, 1967]

§ 2.9 Drawings.

(a) Plans to be filed. In order to facilitate admeasurement, there shall be furnished by the vessel's builder or owner to the collector of customs for the district in which the vessel will be admeasured, either with the application for admeasurement or a reasonable period before admeasurement is scheduled to commence, blueprints or drawings of the following:

(1) A drawing of the cross section in which is shown the construction of the double bottom, if there be one;

(2) An inboard view of the longitudinal section, showing the double bottom, its use or uses, if existing, otherwise the floors, the compartments for water ballast, other than the double bottom, the decks, the superstructures, hatchways, etc.;

(3) Deck plans showing the arrangement and uses of different compartments and deductible spaces;

(4) Drawings showing the arrangement of the engine, boiler, and fuel compartments; and

(5) A tonnage plan showing half breadths of the sections at the points of division of the tonnage length of the vessel into a certain number of equal parts in accordance with the rules for the measurement of spaces under the tonnage deck. The scale or scales of these drawings are to be indicated thereon.

The collector of customs is to be advised of any subsequent changes in the vessel and furnished copies of the corrected plans, or a statement of such changes.

If there are no blueprints or drawings available and if the collector is satisfied that it is impracticable to require such plans to be prepared and made available, considering the size and nature of the vessel as well as the cost and time involved, the vessel shall be measured without requiring their production.

(b) Sketches. When blueprints or drawings are not produced, necessary rough sketches may be made during the course of admeasurement showing the inboard profile, the midship cross-section, the hull and deck arrangements, and related matters, recording any necessary dimensions and showing details of important features such as the depth of side and bottom frames or floor timbers; the dimensions, location, and use of structures and hull spaces; and the thickness of the inner and outer skin. Such rough sketches shall be retained and filed with the other admeasurement papers. The rough sketches made shall not be redrawn to scale unless the admeasurer is satisfied that such action is necessary to insure that accurate dimensions have been lifted, to avoid the necessity for readmeasurement, or to insure against a claim of error which may reasonably be expected to be made in a particular case by the owner or agent. § 2.10 Measurements to be taken at an early stage.

Admeasurement should begin as soon as the vessel is sufficiently advanced in construction to permit its being done, usually when the decks are laid, the hold cleared of encumbrances to admit the
