Subpart G - Flotation Requirements for Outboard Boats Rated for Engines of More Than 2 Horsepower

FEDERAL LAW

183.201 - Applicability

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

(1) Less than 20 feet in length; and
(2) Rated for outboard engines of more than 2 horsepower.

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

Discussion:
Monohull boats under 20 feet in length and rated for more than two horsepower must comply with the more sophisticated flotation system called Level Flotation. The Level Flotation system requires that the swamped boat, loaded with certain weights representing weight capacity, part of persons capacity and some equipment, must float in an approximately level position and not heel past a certain angle, even when part of the passengers’ weight is on one side of the passenger carrying area. The Level Flotation section covers the requirements and tests to perform.
