Foils
Foils are specialized underwater wings that are attached to the hull of a vessel. They work by producing lift as the vessel moves through the water, which reduces drag and increases speed. Foils can be fixed or adjustable, and they come in a variety of shapes and sizes depending on the type of vessel and the conditions it will be operating in. Foils are commonly used on high-speed vessels such as racing sailboats, hydroplanes, and some military vessels. They can also be used on commercial vessels to improve fuel efficiency and reduce emissions.
