Editorial Notes HISTORICAL AND REVISION NOTES Revised section 5101

Source: Section (U.S. Code) 46 App. U.S.C. 86a.

Section 5101 contains definitions that are limited to Chapter 51—Load Lines. Existing Section 46 App. U.S.C. 86a (which defines only the terms "new ship" and "existing ship") will be replaced by section 5101. Definitions of technical terms ("freeboard", "freeboard deck", and "minimum safe freeboard") have been added for clarity. The definition of the term "new ship" has been deleted because the term is not used in Chapter 51. The definition of "domestic voyage" includes the phrase "places in or subject to the jurisdiction of the United States." "Places subject to the jurisdiction of the United States" include deep water ports, production platforms, mining sites outside of territorial waters of the United States but within the United States' Exclusive Economic Zone (EEZ) that was established by Presidential Proclamation 5030, dated March 10, 1983, or on the outer continental shelf. The phrases "economic benefit of overloading" and "weight of the overload" have been defined for purposes of establishing a standard method of determining the value of the cargo with which a vessel is overloaded. The value of the cargo will in turn affect the maximum penalty assessed for overloading the vessel. The definition of "freeboard deck" provides the Secretary with the authority to designate as the freeboard deck either the actual deck (on standard vessels) or another structure (on non-standard vessels). Non-standard vessels, for which this regulatory flexibility is necessary, include shelter deck vessels, semi-submersible multi-hull units, container ships, surface effect vessels, and commercial submarines.
