Two hulls are better than one, according to a growing contingency of yacht owners, designers and builders, who have seen a significant growth in interest in multihulls in the last few years. Stability, safety, and space are considered the three winning qualities of a large power cat, particularly for prolonged periods at sea. Multiple hulls not only tend to deliver a higher, wider beam but reduce motion in big seas. Speed and fuel efficiency are also key considerations, with most fuel-sipping catamarans outrunning monohulls of the same length. Plus, as any naval architect will tell you, a catamaran design reduces water resistance and improves aerodynamics. Other owners take advantage of the space that a twin-hulled layout affords, both inside and out.
