Opposite this, the starboard side offers additional seating and a well-equipped wet bar area with dual electric grills, a stainless steel sink, and dual refrigerators. The cockpit is shaded by a standard hardtop standing six feet seven inches above the deck, with optional sunshades and an extendable SureShade awning that increases covered space aft.

Forward Seating and Entertainment

Additional amenities include a Fusion stereo system with connectivity, beverage holders, and strategically placed grab handles to enhance safety and ease of movement.

Interior Living Spaces and Accommodations

Below deck, the 400 SLX offers comfortable accommodations suitable for overnight stays. The main cabin features six feet three inches of headroom and wraparound seating around an expandable pedestal table that can convert into a berth for two. Storage is abundant beneath the seats and in various compartments, complemented by a 32-inch TV mounted on the port bulkhead, a refrigerator, and a microwave. A mid-berth provides additional sleeping space for two, with generous storage and overhead clearance. The boat also includes a wet head with a hall-side window, a mirrored storage cabinet, a vessel sink set on a Corian countertop, and further storage below, ensuring convenience and comfort for extended outings.
