On a ketch it is called wishbone ketch and is considered a subtype of ketch rigging. A wishbone ketch rigged vessel is a vessel that is rigged as a ketch where a permanent splitting gaff is mounted between two masts. Contrary to the gaff rig (where the gaff is hoisted together with the sail) the gaff stays in the mast. The gaff is typically fixed on the first mast (the one closer to the front) and fixed via a
Ketch Sir Francis Chichester's earlier "Gypsy Moth" ketches had five staysails (each of almost equal size), none of which were boomed. If a ketch has no jibs, it is called a "cat ketch" or a "periauger". On older, larger ketches the main mast may in addition carry one or more square rigged topsails.

Other similar craft include the snow and the pink. Both the
