The Delta 400 SW is the flagship in Delta’s “Sidewalk” series of all-weather express cruisers. With its accessible deck areas, spacious interior, extensive equipment list and high performance, the Delta 400sw is devised to be used year-round as a reliable partner in all your activities at sea. The asymmetric deck layout allows for increased interior space while providing safe passage between the stern and the bow of the boat, even in the most challenging weather conditions. 

The 400 SW has the same high-end Scandinavian appointments that Delta Powerboats is known for, but her beauty is not just skin deep. The vinylester/GRP laminate is cored in Divinycell, providing a displacement of under 20,000 lbs. for her stepped deep vee hull.

The Delta 400 SW offers a sundrenched single level all weather helmdeck with 360-degree panoramic sightlines and a powered glass sunroof complete with sunshade. 

The interior of the deck house includes a fully equipped galley to starboard and comfortable seating in the raised dinette to port. Move easily from indoor to outdoor through the large sliding glass door, or through the captain’s pantograph-opening door on the starboard side. Her asymmetric “sidewalk” layout makes anchoring or docking safe in virtually all conditions. 

The helmdeck flows seamlessly to the aft cockpit via the large sliding glass door. A portside dining area can convert to a large sunbed, and a large swim platform with easy access to the water. 

The belowdecks arrangement includes accommodation for six within three cabins. An owner’s stateroom forward nestled in the bow, a double guest cabin amidships accessed from below and an aft cabin accessed from the helmdeck. All are fitted with Comfort mattresses and heated by an Eberspächer diesel heater. The spacious head is outfitted with a Duravit Bacino basin and Vola fittings, with a large walk-in shower with glass doors.
