Subpart H - Flotation Requirements for Outboard Boats Rated for Engines of 2 Horsepower or Less

FEDERAL LAW

183.301 - Applicability

(a) This subpart applies to monohull outboard boats that are:

(1) Less than 20 feet in length; and
(2) Rated for manual propulsion or outboard engines of 2 horsepower or less.

(b) This subpart does not apply to sailboats, canoes, kayaks, inflatable boats, submersibles, surface effect vessels, amphibious vessels, and raceboats.

Discussion:
Manually propelled boats and boats rated for outboard engines of 2 HP or less must comply with the Modified Level Flotation requirements. As the name suggests, Modified Level Flotation is similar to Level Flotation, but with variations in the persons weight and capacity weight numbers. Section 6.0 discusses the calculations, tests and other requirements.

NOTE:
Level Flotation may also be applied to inboard boats, outboard boats of less than 2 HP, and non-powered boats. Nothing in the regulation says that a boat may not be manufactured to comply with a flotation system superior to the one required. These are only minimum requirements. Many manufacturers choose to install Level Flotation in boats that do not require it.
