A Genoa sail is a type of headsail used on sailing vessels, typically larger than a standard jib. It is characterized by its large size and is often set on a furler, allowing for easy deployment and retraction. The Genoa extends past the mast, providing increased sail area and improved performance, especially in lighter winds. This sail is commonly used in racing and cruising, as it enhances a boat's speed and maneuverability. The Genoa is usually made from durable materials like Dacron or Mylar, ensuring it can withstand various weather conditions while maintaining its shape and efficiency.
