No matter how beautiful or comfortable your yacht is when moored, how it performs when moving through the water is key to how satisfied you'll be with your vessel. Large yachts are built to cruise vast distances and must be able to meet any kind of weather and sea conditions safely and in relative comfort.
That is why GCMNA studies and analyzes the hydrodynamic properties of your yacht. Using a combination of informational tools and computational fluid dynamics, we model your hull and its attachments to reduce drag, enhance maneuverability, maximize seakeeping ability and optimize performance.
Building and testing a scale model
We also create an exact scale model of your yacht's hull and test it. The hull model includes rudders, propellers and tunnels, stabilizers and other hull attachments that influence performance.

To test the scale model, we often use Vizon SciTec's Ocean Engineering Centre in Vancouver, British Columbia, which specializes in testing large motor yachts. The facility offers a 67 m X 3.7 m towing tank, a maneuvering basin, and a computer-controlled flap-type 32-ton wavemaker, which allow us to study the model hull's motion, resistance and sea-keeping in regular waves, random seaways and still water.
The towing carriage is equipped with a 16-channel data acquisition system. Underwater photography windows allow us to visualize flow. The photographic equipment records both digital stills and motion pictures which lets us study and analyze the data repeatedly.
We have also used additional towing tank and testing facilities around the world, including the Maritime Research Institute Netherlands (MARIN) and the Center for Maritime Systems at the Stevens Institute of Technology in New Jersey.
Testing in calm waters
The long tank through which the hull replica is pulled provides us with data on the yacht's propulsion. While the hull is dragged through the tank at different speeds, we study resistance, how waves affect flow patterns, wake patterns and how speed affects flow patterns, vibration and cavitation.
Testing your yacht's seakeeping ability
Comfort while cruising or at anchor strongly influences how much you will enjoy being aboard your yacht. Rolling while anchored can be more unpleasant than moving through waves. We study your yacht's seakeeping ability, and design the hull and such attachments as stabilizers to maximize your comfort.
Testing your yacht's maneuverability
To create a truly hydrodynamic yacht that navigates efficiently and comfortably in all sea conditions takes much research, both computationally and with a scale model simulating realistic conditions. To design such a vessel, we evaluate and test how the yacht will:

To create a truly hydrodynamic yacht that navigates efficiently and comfortably in all sea conditions takes much research, both computationally and with a scale model simulating realistic conditions. To design such a vessel, we evaluate and test how the yacht will:
- Perform in harbor conditions
- Moor in tight or windy conditions
- Turn in minimal space
- Maintain stability and avoid rolling while at anchor
- Minimize yawing, heaving, pitching and rolling in a variety of seaways
- Run before the wind
- Stop short in an emergency
- Perform when on autopilot
- Be affected by attachments and appendages
- Maintain course
- Perform operationally in dire conditions.
