Nautitech lays claim to the performance side of the luxury-catamaran market. The 47-foot model, while expensive, shows how. Although it's a large catamaran, at 47 feet, it's not intimidating. It's powerful and light, and from its twin stern steering stations, the helmsman can feel the wind, and sail controls are easy to reach. A good view can be had from either helm, and although the helmsman is exposed, he or she can retreat inboard with an autopilot remote.
