The DELTA 400 is the original DELTA all-weather boat with a few new design features. The 40 has been setting trends since her introduction in 2007 as the first and only motor boat built with vacuum technology in vinyl ester and divinycell ("Diab Core Infusion Technology"). The newly designed 400 maintains mostly all engineering features as the 40 and continues DELTA's crisp, modern interiors. DELTA has added a functional seating and entertaining area on the aft deck with cushioned benches and a spacious teak table.

With her advanced, stepped hullform, incredible rigidity and light weight, the 400 responds immediately to helm inputs up to 45+ knots under standard power. With available joystick control, docking maneuvers are a breeze. Advanced hull and propulsion yield amazing fuel economy. The DELTA 400 is another uncompromising option for those looking for a family-friendly, fast, seaworthy, and comfortable boat that can be enjoyed in any weather, all year round, and with any mission in mind.

The interior is crafted with materials such as satin teak, Corian, and glass mosaics. To forward is a large cabin with plenty of headroom, double bed, and ample storage for clothing and gear. An ensuite head comes complete with toilet and shower and finishes using Corian. To aft is a split-twin stateroom for guests or children. The salon table can accommodate up to nine people in raised cushions for best visibility through the large picture windows. The galley has been updated with white countertops.

The helm is designed with all the necessary functions within reach of the operator and enough room for a large navigation screen. The 400 includes aft-access to the bow on the starboard side with teak floors leading the way.
