The star latch assembly provides an automatic hookup of the traveling surf at the receiving ship without having to send a rigger aloft. It is disconnected remotely from the deck level when the rig is ready to be returned.
The traveling surf is a specially designed steel block with two high speed roller bearing sheaves. It has two padeyes that provide attachment points for the surf hook pendant assembly or star latch assembly. A padeye on the bottom provides an attachment point for the threefold retrograde system. It provides a return fairlead for the delivery ship's outhaul whip at the receiving ship.
