Davit winches must be fitted if the height of the deck on which lifeboats are carried exceeds ___ from the lightest sea going draft of the vessel.

The concept here is the safety of launching lifeboats from vessels with high freeboard. When the deck carrying the lifeboats sits more than about 20 feet above the waterline in the lightest sea-going draft, manual lowering becomes impractical and risky. A davit winch provides the powered, controlled lowering needed to safely deploy the lifeboat from that height, reducing effort, controlling speed, and preventing a hazardous drop. At lower heights, manual lowering is typically feasible, so winches aren’t required. That’s why 20 feet is the threshold.
