Lightweight rescue boat davit

Abstract

A SOLAS-compliant rescue boat davit for storing, launching and retrieving a rescue boat. The rescue boat davit has an A-frame lifting arm that supports the rescue boat in a stowed position and rotates approximately 20° about the base of the A-frame to assist in hoisting and lowering the rescue boat. A sheave assembly and a davit stop fitting assembly are mounted on the apex of the A-frame lifting arm and accommodate a winch line at the A-frame apex. An electrical winch hoists and lowers the rescue boat, via the winch line, and a stop ring on the winch line operates in conjunction with the davit stop fitting to cause the winch line to rotate the A-frame lifting arm forward. A post assembly mounted to the transom of a ship provides a mount for the electrical winch and supports the A-frame lifting arm via a wire strop. A boarding platform is also mounted to the transom of the ship to permit boarding of the rescue boat in its stowed position.
