NISI luxury yachts are built to the highest safety and construction standards. All NISI yachts over 22 meters are built to RINA Yacht classification. NISI's debut model, the multi-award winning NISI 2400 is built to RINA Charter Class and MCA Commercial (MNG280) certification. NISI 2400 is the first and only yacht in the world under 24-meters to achieve these standards.

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.
