First there was the catamaran, then with its evolution SWATH was constructed, and with the evolution of both came the high speed non-vacillating hydroairy ship.
A catamaran is a type of boat or ship consisting of two hulls joined by a frame. Although the principles of sailing are the same for both catamarans and monohulls, there are some differences to sailing catamarans like the fact that they are far more stable and have a higher average speed.
The Small Waterplane Area Twin Hull (SWATH) is a twin-hull ship design that minimizes hull volume in the surface area of the sea. By minimizing hull volume in the sea's surface, where wave energy is located, the vessel becomes very stable, even in high seas and at high speeds. Placing the majority of the ship's displacement under the waves is similar in concept to submarines, which are also not affected by wave action.
SWATH was first used in the 1960s and 1970s as an evolution of catamaran design for use as oceanographic research vessels or submarine rescue ships.
The Hydroairy Ship or boat is a type of vessel consisting of two tubes joined to the frame by struts. The Hydroairy ship is an upgraded design of a catamaran and a SWATH vessel.
The first such ship was constructed and manufactured in 1990.
