(c) At each port or station where there is no full-time customs employee, the hours during which the customs office will be open for the transaction of general customs business shall be fixed by the district director of customs concerned with the approval of the regional commissioner of customs, and notice thereof shall be displayed prominently at the principal entrance of the office. (d) Each customs office shall be open for the transaction of general customs business on all State and local holidays occurring on days other than Saturdays, Sundays, and national holidays. If a State or local holiday interferes with the performance of work in a customs office by any customs employee or employees,, the principal field officer may request approval of the regional commissioner of customs to excuse such employees from duty without charge to leave. (e) Customs services required to be performed outside a customs office shall be furnished between the hours of 8 a.m. and 5 p.m. (or between the corresponding hours at ports where different but equivalent hours are required for the maintenance of adequate service and are approved by the Commissioner of Customs) on all days when the customs office is open for the transaction of general customs business.

(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. The higher net 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) In ascertaining the net tonnage, no space may be deducted unless it has previously been included in the gross tonnage. [28 F.R. 14553, Dec. 31, 1963, as amended by T.D. 66-57, 31 F.R. 4295, Mar. 11, 1966] § 2.7 The marine document. The marine document of every vessel 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 (L) 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. [T.D. 66-57, 31 F.R. 4295, Mar. 11, 1966] § 2.8 Application for measurement. The builder of a new vessel required to be admeasured, or the person having supervision of changes and/or alterations (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 required depths and breadths being properly taken; before the engine and boilers are installed and accommodations are partitioned off. § 2.11 Uniform system required. (a) The following directions are given showing the progressive steps to be followed in the process of admeasurement. It is important not only that the rules be followed, but that required measurements be taken and calculations made in a uniform and correct manner that one general system may prevail throughout the service respecting this subject. (b) Measurements taken aboard are to be recorded in the "Memorandum of Dimensions" known as Form 1413. § 2.13 Measuring instruments. (a) The measurements should be made with a waterproof tape, graduated into feet and tenths of a foot, and as nearly inelastic as possible. (b) Sliding rods which are of three sizes: One 3 feet long for taking depths from 3 to 5.8 feet; another 6 feet long for taking depths from 6 to 11 feet, or, with the extension piece attached, to 16 feet; and a third one 11 feet long for taking depths from 11 to 21 feet, or, with the extension piece attached, to 26 feet. The movable or index rod in each has an arrow index traversing a decimal scale on the fixed rod. Greater depths may be taken by inserting into the ends of the index rods, an extension piece, provided with sockets for this purpose one or more joints of lift rods described below: The fixed rod is graduated in feet (in red) and tenths and half-tenths (in black). and when the ends of the rods are well together the arrow on the index rod points to the figure indicating the constant length of the fixed rod, and as the index rod is moved up the arrow indicates the length from the upper end thereof to the lower end of the fixed rod. Bear in mind, however, that when you use any of the attachments referred to above you must add to the reading on the fixed rod the net length of the attachment used; e. g., if the 6-foot rod is extended to its limit, 11 feet, which is reached when the arrow on the index rod is fair with the upper end of the fixed rod, and the extension piece is attached, which is done by slipping the bands on the lower end of it over the upper end of the index rod until the upper edge of the upper band is fair with the upper end of the index rod, and by fastening (on the groove side of the index rod) with set screws in the said bands, the length will not be 11 feet, as shown by the reading, but 16 feet, the reading plus the increment due to the attachment (11 feet +5 feet). This increment may be further increased by inserting into the end of the extension piece one or more joints of lift rods, each of which is about 3.95 feet when adjusted. At the station of the area to be measured in single-deck vessels the rod is to be placed on the ceiling, or floor beam or timber when no ceiling is present, alongside the keelson or line of the keel, perpendicular or square thereto, and also parallel to the middle longitudinal plane of the ship, and forced up firmly under the deck and fixed in such position by the set screws; from the depths thus found take one-third of the round or one-half of the pitch of beam to get the depth of the area. The depth of an area taken as above is to be divided into the required number of equal parts. (See § 2.29 (d).) With the rod fixed in position as above, set off on it from its lower end one of these equal parts, or common interval between the breadths, using white or other colored chalk or material that will make a visible mark, which gives the position of the first breadth above the bottom breadth, and from this when the rod is taken down the positions of the remaining breadths are to be set off at the said common interval. The positions of all the breadths being thus severally marked on the rod, it is then to be set up again and firmly fixed or held in position, and the breadths may be readily and correctly measured by means of the tape |
