As the name suggests, a catamaran is a vessel consisting of two single hulls horizontally joined together.
Humans first used catamarans because they discovered that connecting two ships horizontally allowed for safer navigation from inland rivers to the sea without the risk of capsizing. This method was initially used on sailing ships, creating catamarans that could withstand larger waves at sea. Furthermore, it was discovered that catamarans offered significantly more deck space and cargo capacity than monohulls of the same tonnage, leading to their use in cargo ships. After the 1960s, with the rapid development of high-speed passenger transport at sea, high-speed catamarans, due to their large deck area, spaciousness, and suitability for luxurious decoration, became widely favored and have become the fastest-growing, most widely used, and most numerous type of high-performance vessel in recent decades.
A typical high-speed catamaran consists of two slender monohulls (called hulls) connected by a deck bridge. The hull houses the propulsion system, power station, and other equipment, while the superstructure, containing passenger cabins and living facilities, is located above the deck bridge. High-speed catamarans, by dividing a single hull into two slender sections, reduce wave-making resistance, resulting in higher speeds, typically reaching 35-40 knots. Because catamarans are much wider than monohulls, their stability is significantly superior, and they are capable of withstanding larger waves. Furthermore, catamarans offer excellent maneuverability, minimal drag peaks, and large carrying capacity, making them widely used in military and civilian vessels worldwide.
