Title 46 › Subtitle II — Vessels and Seamen › Part C — Load Lines of Vessels › CHAPTER 51 — LOAD LINES › § 5101
Gives plain meanings for key words used in the chapter. "Domestic voyage" means moving a vessel between places in the United States or places under U.S. control, but not travel between a U.S. territory or possession (or the Trust Territory of the Pacific Islands) and a place outside that territory. "Economic benefit of the overloading" equals the overload weight in tons times the smaller of the trip’s average freight rate per ton or $50. "Existing vessel" means a ship whose keel (or similar stage) was laid before January 1, 1986 for domestic voyages, or before July 21, 1968 for foreign voyages. "Freeboard" is the vertical distance from the assigned load-line mark to the freeboard deck. "Freeboard deck" is the deck the Secretary sets by regulation. "Minimum safe freeboard" is the freeboard the Secretary decides cannot safely be reduced. "Weight of the overload" equals the inches the vessel sits below its assigned freeboard multiplied by the vessel’s tons-per-inch immersion factor at the assigned minimum safe freeboard.
