Question 1266 Deck Safety

The correct answer is B) Radial. Radial davits are not considered mechanical davits for the purposes of US Coast Guard Captain's License Examinations. Mechanical davits are defined as those that use a mechanical advantage, such as gears or winches, to assist in launching and recovering a lifeboat or other survival craft. Radial davits, which pivot on a central point, do not have this mechanical advantage and are therefore not classified as mechanical davits. The other options, A) Crescent, C) Sheath-screw boom, and D) Quadrantal, are all types of mechanical davits that use a mechanical advantage system.
