US Watercraft builds hard-working boats in aluminum, steel, and composites. We have the exclusive licensing agreement with SeaArk Marine to utilize its portfolio of proven and reliable commercial designs. In addition to the SeaArk Marine fire-fighting, law enforcement, military, survey, landing craft, and workboats, we also build custom catamaran and monohull designs. We are the commercial boatbuilding division of Waterline Systems and we have more than 30 years of experience in high-performance vessel construction. With new builds and service under one roof, we support each vessel throughout its lifetime.
