___ davit arms are hand-cranked out over the ship's side by screw, gears, or other means.

Mechanical davit arms are operated manually with a hand crank that turns screws or gears to swing the arms out over the ship's side. This manual gearing setup is what distinguishes them from gravity davits, which move mainly by the weight of the boat and don’t rely on a hand crank to extend the arms. Radial describes how the arms are arranged around a point, not how they are actuated, and single-point refers to the mounting method rather than the operation. So, the description of being hand-cranked out over the side best fits mechanical davits.
