The team of naval architects and engineers at Gregory C. Marshall Naval Architects (GCMNA) covers all aspects of a yacht's design from the first inspirational brainstorming session with you, the client, to the sea trials that validate the vessel's performance.
Our staff collaborates on all facets of the design and engineering to meet meticulously developed specifications. This integrated effort makes sure your yacht is of the highest quality and will be delivered in an efficient, timely and cost-effective manner.
But there is more to yacht design than efficiency and engineering formulas. To create the yacht that satisfies your dreams demands a balance of art and science, of creativity and technology, of appearance and performance.
It's 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 disciplines needed to create a world-class yacht — vision, 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.
The best boats result from a collaborative effort between the owner and the design team. We work with you. We listen to you. Jointly developing the ideas for your yacht is exciting, rewarding and fun.
GCMNA's services offer exceptional advantages
Although our design team has decades of experience in naval architecture, GCMNA is not the largest design firm on the globe. So how can we offer tailor-made, complete yacht design solutions?
We have invested in technology — in hardware and software — and, as important, in the training to use these systems effectively and creatively. Here are some examples of what we do differently.
Consistent 3-D modeling
We provide you with drawings of every aspect of the yacht in 3-D model images. This type of modeling yields clear-cut advantages. You can view your yacht from every angle. In addition, 3-D imaging is more exact and often reveals unused spaces that can be made available for such things as fender storage or built-in seating. With our precision design, portions of the yacht can be constructed anywhere the skills are available. For example, while the hull is under construction in one location, the woodwork can be built somewhere else, thus speeding up your yacht's completion. Moreover, the modeling allows designers, owners and boat yards to grasp the overall contours and details of the yacht early on, thereby minimizing change orders.
The showcase cabin
With the click of a key, we can show you in 3-D imagery how each room in the yacht looks in mahogany, cherry, teak or any other wood you might choose. We can instantly switch the fabrics and wall coverings, choosing among thousands of colors. We can show you the effects of different art objects, novel lighting, or different carpet. This capability gives you true choices in what your interior will look like.
GCMNA's real-time communications
Using computers and telephones, we have developed the in-house ability to communicate with clients and shipbuilders in real time. No matter where you and the yacht builder are located, we consult with you directly and solve problems or make changes during our discussions.
To illustrate, let us assume that you, the design team and yacht builder are on-line reviewing the layout of the master stateroom. You'd like to try an alternate arrangement. Our naval architects pull up the stateroom's drawing and, sketching directly on an electronic drawing pad, change the configuration. Simultaneously, we discuss the implications of the alterations: How do the changes influence closet size? Are the heads affected? Must mechanical equipment be realigned? Our technology allows us to revise the layout until you are satisfied and the builder concurs the modifications are feasible.
GCMNA prepares the complete package
Often, yacht design and the construction phase of yacht building are separate entities. The naval architect prepares the profile, arrangements, interior and structural engineering. The builder creates or contracts out shop drawings and schematics for electrical and mechanical systems and joinery. The yard staff use their experience to install the pieces, sometimes puzzled about how it should all fit together.
More planning, less puzzling. GCMNA can unite these different phases in a "virtual build process" and reduce on-site conflicts and changes. We design your yacht and know how it comes together, from the engineering specs to the decorations. Moreover, our complete approach makes excellent business sense. Here are just some of the advantages:
