A keelboat is a type of sailing vessel that features a fixed keel, which helps provide stability and balance while sailing. These boats are typically larger than small dinghies and can be used for various purposes, including racing, cruising, and fishing. The keel allows the boat to sail efficiently against the wind, making it a popular choice among sailors. Keelboats come in various designs and sizes, accommodating different numbers of passengers and cargo. They are often equipped with sails, a rudder, and sometimes an engine for propulsion. Many keelboats are used in competitive sailing events, such as those organized by ISAF or World Sailing.
