Catamarans have been used for centuries in the form of two hulls connected in parallel relation, for commercial and exploratory purposes. In more recent times recreation has become a widely enjoyed possibility and the speed potentials of catamarans have become appreciated and exploited in sailboats and powerboats. In the case of small boats such as dinghies for one person to operate and one or two others along for the ride there is a wide choice of monohulls for every purse and fancy, but small catamarans, such as the very successful Hobie Cat sailboats, while performing well for their design purpose of racing, are ill suited for being rowed or powered by motor, or for relaxed activities such as fishing. So an unfulfilled demand has built up for a boat hull which has the speed and stability advantages of a catamaran, which is compact and inherently strong and practical to build, which can perform well when under sail, when towed, when powered by motor, and when towed behind a larger boat, and has floatation and reboarding abilities that improve stability and help in getting aboard swimmers or those in trouble in the water.
