Catana enjoys the reputation as the builder of the fastest production luxury catamarans. Design features unique to Catana are: - Asymmetrical hulls, which help prevent hobby horsing and aids in preventing the leeward hull from being buried in a wave when sailing to windward at high speeds. In addition, all weight is concentrated toward the center of the hulls making sure weight is kept to a minimum forward of the mast. - Daggerboards, which offer very shallow sailing with boards up and closer windward sailing angles with boards down. In addition, there is an extra margin of safety when sailing in heavy wind-sea conditions due to the ability to raise the daggerboards and "slide" off the face of extremely high waves. Each Catana is constructed using vacuum-molded unidirectional roving impregnated with isophthalic resin. Kevlar and carbon fiber are used in high load-stress areas. The entire structure is cored with high-density Divinycell closed cell foam and all bulkheads are vacuum molded and cored with end-grain balsa. Each customer has total input as to the design and finish of their interior. Sailing a catamaran doesn't have to remind you of driving a bus. If you enjoy the thrill of sailing, prefer better all-around performance without sacrificing safety, and demand the highest quality, then you owe it to yourself to closely inspect a Catana catamaran. The Catana 531 was first introduced in 1994, and is the flagship of Catana Chantier. The C531 offers luxury and performance on a grand scale unmatched by any other catamaran builder. The interior layout is custom designed to meet the customer's exact requirements.
