A large sail formerly used with the wind aft or quartering. It
was a square sail cut like a studding-sail, and set with a great yard on
the end of the spanker-boom, across the taffrail. The name latterly has
been officially applied to the spanker, both being the aftermost sails
of a ship, the ring-tail being only an addition, as a studding or
steering sail. (See STEERING-SAIL.) Also, the foremost spur in the
bilge-ways, the heel of which is fayed to the fore-side of the foremost
poppet, and the sides of it look fore and aft. Also, a sort of
fishing-boat.
