The popularity of multihulls among sailors today is nothing short of revolutionary. Forty-two multihulls lined the boat-show docks in Annapolis last October, and the Multihull Demo Days took 1,500 people on test sails. Three catamarans and one tri constitute this years Cruising Multihull category: the Manta 42, the Fountaine Pajot Belize 43, the Catana 472, and the Dragonfly 1200. The prize goes to a Danish-built marvel of engineering: The Dragonfly 1200 trimaran. Folding amas for docking in traditional slips, cruising speeds of 15 knots under power, and Pullman-car elegance in the accomodations all tipped the scales in this boats favor.
