lateen

The Spanish jabeque had only lateen sails, as portrayed in the Cazador.

The lateen style triangular shaped sail was used in the Mediterranean as early as the Antique time.

For instance, barge-like vessels in the American maritimes north of Boston, called gundalows, carried lateen rigs throughout the late nineteenth and early twentieth centuries.

That hardly mattered, for no other ship in the region carried the distinctive design of the Sea Sprite, the three masts of billowing triangular, lateen sails.

There is a suggestion that the rig was sometimes used in a lateen style with the top cross spar dipped at an angle to aid sailing to windward i.e. the spar became the luff.
