Davit Guy
Sea Terms
A light wire rope secured in the outer eye on the side of each davit, and set taut on the rail by a lanyard so as to keep the davits at right angles to the keel. The davit check or spreader (a chain) crossing horizontally from davit to davit prevents them from turning too far when the guys are set up. Sometimes a light spar called a strongback is used for spreading the davits instead of a chain.
