A multi-hulled yacht or boat is also known as a catamaran. The official Definition is: A multi-hulled boat has at least three hulls, with the outside hulls extending forward beyond the central or inside hull or hulls.The hulls are tapered with a cross-sectional configuration that increases in side front to rear, thus forming a channel or tunnel between adjacent hulls which decreases in cross-sectional size front to rear. Air entering the tunnels is compressed, thus imparting a lifting force to the hulls lifting the hulls partially out of the water to decrease the hydraulic drag on the hulls.Multi-hulled boats are often offered for charter vacations around the world. An example of a multi-hulled boat is the Aldebaran located in the Caribbean: www.bookaldebaran.com

There are two different elements to a keel. They are the hydrodynamic element and the structural element. In layman terms, the keel is the backbone. There many different hulls. When you speak of hulls, you have displacement hulls, semi-displacement hulls or planing hulls. Hulls come in different shapes like moulded or hard chined or simply chined.
