On which type davit does the davit head stay at the same height?
AI Explanation
The correct answer is A) Radial.
In a radial davit system, the davit head stays at the same height as the boat is lowered or raised. This is because the davit arm pivots around a central point, maintaining the same vertical distance between the davit head and the water's surface.
The other options are incorrect because they do not exhibit this characteristic. Gravity davits rely on the weight of the boat to lower it, sheath-screw davits use a threaded mechanism to adjust the height, and quadrantal davits pivot in a curved motion, causing the davit head height to change.
