The 400 has evolved from the successful 350/390 line. Aesthetically, she is a mix of traditional and modern lines, which makes her a bit odd at some angles, but she always gathers admiring looks from other boaters in the anchorage. One of the nice features is the lighted overhang shading the saloon windows from the midday sun and lighting the walkways in the evening. The fuel tank humps in the walkways of the 390 have been eliminated by raising the entire main deck about 6 inches. The swim platform bussel has been removed and the hull lengthened about 36 inches.

The transom door has been moved to one side which should allow access to the swim platform, even with a small dinghy on the swim platform. The straightened staircase to the flybridge makes much better use of space in both the cockpit, and on the flybridge. There is storage under the staircase for buckets and brushes. The overhangs have gutters that drain thru the rear supports and then to overboard drains at the transom.

All the windows have been restyled and frames upgraded to polished aluminum. The rounded corner window frames and a steeper windshield angle give this boat a "salty" look. Plenty of hatches and portlights for ventilation. Center windshield section also opens

Stella Blue's galley has corian countertop, double bowl sink, three burner stove and oven, 6.8 cu.ft. refridgerator/freezer, microwave, coffee maker, and lots of cabinet space.

The addition of the dinette allows the convertible sofa to be used as a third bunk space, without the need to move the Hi-Lo table around as in the 390. In the 390, cabinets obstructed much of the window view. In the 400, the full height of the taller saloon windows are open to full view and give the boat a larger and more airy feel.
