After sail refers to a specific type of sail that is set or hoisted on a ship or boat after the main sails have been deployed. Also known as a supplementary sail or an auxiliary sail, the after sail serves to provide additional power, control, or assistance to the vessel's propulsion system. It can be set on a boom, lateen yard, or any other suitable spar situated behind the main mast.
The purpose of an after sail can vary depending on the specific requirements of the ship. In some cases, it may be employed to augment the vessel's speed by capturing additional wind, particularly when sailing downwind. It can also contribute to maintaining stability in challenging wind conditions, which is especially crucial on sailing ships with multiple masts. Additionally, the after sail may act as a means of maneuvering the vessel by allowing the crew to adjust the ship's course or attitude.
After sails can come in various shapes and sizes, depending on the design and requirements of the ship. Some common types include the mizzen sail, the jigger sail, and the jib. These sails are often found on larger sailing vessels, such as schooners, ketches, and yawls.
Overall, after sails provide valuable assistance to seafarers, offering versatility and adaptability in different wind and sea conditions. Their presence enhances a ship's performance, making them an essential tool for navigational control and propulsion in the world of sailing.
