70% to pass

When lifeboat winches with grooved drums are fitted on a vessel the lead sheaves to the drums shall be located to provide fleet angles of not more than _______________.

A 4°
B 8°
C 12°
D 16°
AI Explanation

The correct answer is B) 8°. When lifeboat winches with grooved drums are fitted on a vessel, the lead sheaves to the drums shall be located to provide fleet angles of not more than 8°. This requirement is specified in regulations for the design and installation of lifeboat winches to ensure proper and safe operation of the lifeboat launching system. The other options are incorrect because a fleet angle of 4° is too restrictive, 12° is too large, and 16° would exceed the recommended maximum fleet angle for proper and safe operation of the lifeboat winches.
