New Amasea 84 Catamaran Who is Amasea Yachts? This is a relatively new company that is looking to break into the market with an 84-foot (25-meter) motor catamaran called the Amasea 84. They are claiming to use new techniques in building a motor catamaran by utilizing metal (instead of fiberglass) and building on a three-deck basis instead of two. "The project is developed for live aboard and long-range ocean cruising," said CEO and Founder Jack Wijnants. "The yacht is designed on the limit of legal 'small craft' range, due to the fact that catamarans provide accommodation spaces comparable with much larger yachts."
