A multihull catamaran is a type of boat composed of two hulls, or "cats", connected together in such a way that allows the boat to sail effectively on open water. Catamarans can be propelled by sail power, engine, or a combination of both. Catamarans provide excellent stability and performance and are highly sought after by sport fishers and other recreational boaters. Catamarans are easy to manoeuvre, even in rough waters, and often feature cutting-edge technology. They are also known for their speed, with some catamarans reaching speeds of up to 40 knots. Multihull catamarans are also popular for racing, cruising, and sailing.
