Definition

Noun: A fore-and-aft topsail is a specific type of triangular sail used on sailing vessels. It is set above a larger fore-and-aft sail (like a gaff sail) and is characterized by having its bottom edge (foot) attached along a spar called a gaff and its forward edge (luff) running up along the topmast.

Usage

This term is used exclusively in the context of traditional sailing and nautical terminology to describe a specific sail arrangement on boats like schooners or other gaff-rigged vessels. * The sailor climbed aloft to reef the fore-and-aft topsail before the storm hit. * On a gaff-rigged schooner, the fore-and-aft topsail is set above the mainsail.

Advanced Usage

• The fore-and-aft topsail is often simply called a gaff topsail. This sail is used to increase the total sail area and improve a vessel's performance, especially in light winds.
