About the firm

Oak Hill Marine Design is a naval architecture practice in Southwest Harbor, Maine, specializing in commercial powerboats up to 70 feet in length. Founded in 1995, it provides complete design packages for workboats, passenger vessels, and yachts built to aluminum, steel, or fiberglass construction standards, with drawings prepared to Lloyd's or ABS requirements. Full-size 3D computer lofting using AeroHydro MultiSurf is a core capability, encompassing plate expansion, hydrostatic analysis, and CNC-ready parts output. Oak Hill Marine Design also handles refit and modification of existing vessels and offers both manual and CAD drafting services for a broad range of marine projects.
