Title 46 - Shipping
(a) The load line regulations in this part are complementary to those in part 42 or part 45 (Great Lakes load line regulations) of this subchapter, as reference is made thereto. [CGFR 65–50, 30 FR 16755, Dec. 30, 1965, as amended by CGFR 68–60, 33 FR 10076, July 12, 1968] (a) A steam collier is a vessel mechanically propelled, and specially designed for the carriage of coal in bulk. (b) A towed barge is a vessel without sufficient means of self-propulsion and which requires to be towed. (c) A self-propelled barge is a vessel mechanically propelled of the type specially designed for use in limited coastwise and Great Lakes service and capable of transiting interconnecting canals. (a) The load line marks on the vessel's sides must be in accordance with §42.13–25(a) of this subchapter, except seasonal markings such as “Winter North Atlantic” which are not applicable to the voyage are omitted. (b) In the case of vessels which engage in special services on coastwise voyages and voyages on the Great Lakes, the marks on the vessel's sides are to be in accordance with Figure 44.05–10(b), except that the lines marked “SW” and “MS” shall be used only where applicable. (c) The load lines aft of the combined disk and diamond will be applicable for voyages on the Great Lakes and those on the forward side will be applicable to limited coastwise voyages. The summer line on the ocean will correspond to the summer line on the Lakes and the winter line on the ocean will correspond to the intermediate line on the Lakes. (d) In the case of vessels which operate both on special service coastwise voyages and on unlimited coastwise voyages, the marks on the ship's sides are to be in accordance with figure 44.05–10 (d). The load lines aft of the disk will be applicable to voyages in special service coastwise or inter-island voyages and those on the forward side will be applicable to unlimited coastwise voyages. (A vessel marked for both special service and unlimited coastwise voyages and furnished with a load line certificate on the international form shall, when entering the foreign trade, arrange that the load line markings are in accord with the vessel's international load line certificate by the elimination of the marks aft of the disk.) [CGFR 65–50, 30 FR 16755, Dec. 30, 1965, as amended by CGD 80–120, 47 FR 5723, Feb. 8, 1982; USCG–2004–18884, 69 FR 58345, Sept. 30, 2004] (a) In assigning load lines to an existing vessel the provisions of the regulations in this part shall be complied with in principle and detail insofar as is reasonable and practicable, having regard to the proven efficacy of existing arrangements for a special service voyage, and having particular regard to the provision of sufficient means for the protection and safety of the crew. (b) Where it is neither reasonable nor practicable to comply with this part in its entirety, the assigning authority will, in each case, report to the Commandant, U.S. Coast Guard, the specific matters in which the vessel is deficient with such recommendations as may seem desirable. Upon the receipt of this report the Commandant, U.S. Coast Guard, shall determine such addition to the freeboard as will, in the judgment of the Commandant, U.S. Coast Guard, make the vessel as safe as if it had fully complied with this part. (a) Steam colliers. The conditions of assignment for steam colliers shall be in accordance with the requirements of part 42 of this subchapter, except that in the case of steam colliers constructed with bulwarks, the freeing port may be of a practically continuous slot type, located as low as possible, the clear area of the slot to be not less than 20 percent of the superficial area of the unpierced bulwarks. If, due to sheer, or other conditions, the assigning authority considers that extra local provision should be made for freeing decks of water, the slots are to be located so as to have maximum efficacy. (b) Towed barges. The conditions of assignment for towed cargo barges where the cargo is carried under deck shall be in accordance with §§45.10–5 to 45.10–100 of this subchapter. In the case of tank barges and cargo barges carrying cargo only on deck, compliance will also be required with the supplementary conditions of §§45.20–1 to 45.20–70 of this subchapter. In the case of cargo barges of the open type, assignment will be limited to barges in unmanned operation and the construction of the vessel must be such as to satisfy the assigning authority that no unusual hazards will be experienced. (c) Self-propelled barges. The conditions of assignment for self-propelled cargo barges carrying cargo under decks shall be in accordance with the provisions of §§45.10–5 to 45.10–100 of this subchapter. In the case of self-propelled tank barges and self-propelled cargo barges carrying cargo only on deck, compliance will also be required with the supplementary conditions of §§45.20–1 to 45.20–70 of this subchapter. [CGFR 65–50, 30 FR 16755, Dec. 30, 1965, as amended by CGFR 68–60, 33 FR 10076, July 12, 1968] (a) General. (1) When the assigning authority is satisfied that the requirements of this part as applicable to the type of vessel under consideration are complied with the freeboards will be computed as described in this section. (2) The requirements in §§42.09–1 and 42.09–10 that relate to the assignment of freeboards and to stability are applicable to each vessel subject to the requirements in this part. (3) The assigning authority that assigns a vessel subject to the requirements in this part a freeboard under part 45 of this chapter shall do so in accordance with the requirements in effect as of October 1, 1972. (b) Steam colliers. Steam colliers that have constructional features similar to those of a tanker which afford extra invulnerability against the sea may be assigned a reduction of freeboard from that determined under part 42 of this subchapter. The amount of such reduction shall be determined by the assigning authority, in relation to the freeboard assigned to tankers, having regard to the degree of compliance with the supplementary conditions of assignment laid down for these ships, but without regard to the degree of subdivision provided. The freeboard assigned to such a vessel shall in no case be less than would be assigned the vessel as a tanker, as determined under part 42 of this subchapter. (c) Towed cargo barges with cargo under deck. The freeboard is to be computed under §§45.15–1 to 45.15–97 of this subchapter. The fresh water and seasonal markings where applicable are to be determined under part 42 of this subchapter. (d) Towed cargo barges with cargo only on deck. The freeboard for barges of this type is to be computed in accordance with the requirements of §§45.20–1 to 45.20–70 of this subchapter. The fresh water and seasonal markings where applicable are to be the same as determined under part 42 of this subchapter. (e) Towed cargo barges of the open type. The load line shall be placed where, in the judgment of the assigning authority, the draft will be such that no unusual hazard will be experienced. In general, drafts assigned will be such that the barge will remain afloat with a reasonable freeboard after flooding of the net available open space. (f) Towed tank barges. The freeboard is to be computed in accordance with §§45.20–1 to 45.20–70 of this subchapter. The fresh water and seasonal markings where applicable are to be determined under part 42 of this subchapter. (g) Self-propelled cargo barges. The freeboard is to be computed under §§45.15–1 to 45.20–15 of this subchapter. The fresh water and seasonal markings where applicable are to be determined under part 42 of this subchapter. (h) Self-propelled tank barges. The freeboard is to be computed in accordance with §§45.20–1 to 45.20–70 of this subchapter. The fresh water and seasonal markings where applicable are to be determined under part 42 of this subchapter. [CGFR 65–50, 30 FR 17655, Dec. 30, 1965, as amended by CGFR 68–60, 33 FR 10077, July 12, 1968; CGD 73–49R, 38 FR 12290, May 10, 1973] (a) The load line certificates for a special service coastwise or special inter-island voyage shall be issued in addition to any other applicable load line certificates and shall be on the form shown in §44.05–35.
