NISI advanced composite hulls are independently tested and certified. Systems are fitted to luxury yacht and commercial vessel standards. The Vantage Series features water, fuel, fire-fighting, emergency bilge, and hydraulic systems are fitted entirely with metal plumbing. Engine rooms are encased with aerospace insulation, tested to 1,000°F (538°C), to control heat from reaching guest quarters in the event of a fire for a minimum of 30 minutes. Salon and other floors are floated with added acoustic insulation.

The entire interior forward sections of the hulls along chines and waterline are coated with advanced sound deadening material that further reduces the noise of water-slap, while underway and at anchor. NISI yachts exceed the highest level of engineered quality, safety and comfort standards.
