[1] This rigging is most popular on heavy two-masted vessels.
Examples of wishbone-rigged boats include the Zawisza Czarny and the Norda.
A wishbone ketch rigged vessel is a vessel that is rigged as a ketch where a permanent splitting gaff is mounted between two masts.
The gaff is typically fixed on the first mast (the one closer to the front) and fixed via a line to the aftmost mast.
These lines allow the sail to be trimmed to suit the wind.
