- Company Directory - Gregory C. Marshall Naval Architect Ltd


The team of designer, naval architects and engineers at Gregory C. Marshall Naval Architects (GCMNA) covers all aspects of a yacht’ design, from the first inspirational brainstorming session with our clients to the sea trials that validate the vessel’ performance. GCMNA was established in 1994 by the award-winning naval architect that carries his name. The GCMNA team collaborates on all facets of the design and engineering to meet meticulously developed specifications. This integrated effort makes sure the yacht is of the highest quality and will be delivered in an efficient, timely and cost-effective manner. However, there is more to yacht design than efficiency and engineering formulas. To create the yacht that satisfies the dreams of our clients demands a balance of art and science, of creativity and technology, of appearance and performance. It is this blend of artistry and naval architectural know-how that sets GCMNA apart. Our decades-long experience has taught us the skills to work in close cooperation with clients, shipyards and suppliers in North America, Europe, Asia and New Zealand. We offer all the disciplines needed to create a world-class yacht—, originality, styling, naval architecture, engineering, mechanical and electrical systems, joinery, propulsion and business acumen. Our careful preparations meet and exceed classification society and international standards. GCMNA has a staff of 15 professionals that allows us the resources to take on the most challenging projects, even if it is 30ft or over 300ft. Although our specialty at GCMNA is yachts we have been involved in many commercial projects such as patrol vessels, ferries, fish boats, coastguard vessels and military training vessels.
