D-NPS.SP - rescue boat davit system with docking head, single or double arm.
The docking head will prevent the boat from swinging until lowered by rope only.
With the full complement of persons the boat is launched from the stowed position to the water level. Hydraulic “stored power" will luff the davit to lowering position, gravity will do the lowering. Both motions can be controlled from either the deck position or from inside the boat.
The entry to the craft should be wide enough to handle a stretcher carrying a wounded person.
Hoisting speed according to SOLAS: 18 m/min
