Regatta craft is a term used to refer to the various types of boats that are used in regattas, which are competitive sailing races. The three most common types of regatta craft are sloops, sculls, and sailboats. Sloops are single-masted boats with a jib and mainsail, while sculls are small, lightweight boats that are propelled by a single oar in each hand. Sailboats are larger vessels that are propelled by sails and have a keel for stability.
