, headquartered in Marblehead, Massachusetts, builds semi-custom performance sailing yachts that are cost-effective. Hylas yachts are manufactured at a shipyard named Queen Long Marine in Taiwan. Sizes of the sailing yachts range from 46 to 66 feet long, and include raised saloon and pilothouse versions. Optionally available on the smaller yachts and a standard on the larger yachts is the usage of Twaron™, a special fiber designed to be multiply stronger than steel, and both stronger and markedly lighter than fiberglass. Twaron™ also has the benefit of perforation reduction. Vinylester resins for lamination and two layers of epoxy barrier coat are applied to Hylas yachts, to avoid osmotic blistering. Crusing World Magazine named the Hylas 54 "Boat of the Year" for Full Size Cruiser.
