Fore-and-aft sail is a type of sail configuration used on sailing vessels. It consists of four sails: a spanker (7 letters), a LATEEN (6 letters), a mizzen (6 letters) and a mizen (5 letters). The spanker is a large sail set at the back of the vessel, while the LATEEN is a triangular sail set at the front. The mizzen and mizen are both smaller sails set at the back of the vessel, with the mizzen being slightly larger than the mizen. Together, these sails provide propulsion and maneuverability to the vessel.
