GMT Composites has been at the forefront of carbon fiber innovation and new applications development in both marine and industrial sectors since its founding in 1984. In the marine category, we manufacture carbon fiber masts, booms, and rudders for sailboats and custom carbon boarding systems and accessories for vessels from 20 to over 200 ft. We work closely with builders, designers, owners and yards to design and build custom solutions. Our products, including carbon ladders, Seastairs, and passerelles, are made to exacting standards and featured on Superyachts from ship yards including Delta, Westport, Royal Huisman, Vitters, Claasen, and many others.
