The Seawater Phantom 400 is one of the most renowned Italian RIBs in its class. Designed to offer exceptional offshore performance while maintaining a high level of comfort, it is now a benchmark for demanding boaters looking for a versatile, fast boat capable of handling the most varied sailing conditions.

This vessel features a 2011 hull paired with three 350hp Yamaha V8 engines installed in 2015. With a total output of 1,050hp and only 950 hours of operation, this configuration guarantees outstanding performance. Top speed approaches 60 knots, while a comfortable cruising speed is between 30 and 35 knots.

Thanks to its deep-V offshore hull, the Phantom 400 offers exceptional stability and a particularly comfortable ride, even in rougher conditions. This quality of handling is one of the reasons for Seawater's reputation in the premium RIB market.

The exterior space is perfectly optimized. The boat features a large forward sunpad, a spacious aft seating area with a table, ample seating, and easy movement around the center console. Passengers enjoy generous space, ideal for day trips, anchorages, or quick transfers.

The equipment level has been significantly improved thanks to a major refit carried out in 2026, representing an investment of over €30,000. The work included a major mechanical overhaul, the installation of a new Simrad GPS, a new carbon mast, new sails, and a recently installed high-end drawer refrigerator.

Onboard comfort is enhanced by a Fusion audio system paired with a high-performance amplifier, allowing you to fully enjoy your days at sea. A console cabin with a marine toilet completes the layout and provides added comfort during longer voyages.

Meticulously maintained and equipped with numerous recent upgrades, this Seawater Phantom 400 represents a rare opportunity in the premium RIB market. Its combination of performance, build quality, comfort, and features makes it perfectly suited for fast cruising in the Mediterranean.
