The 2026 Marex 310 Sun Cruiser is a 31-foot fiberglass cruiser powered by a single Volvo Penta D6-440 diesel engine. Built as a family cabin cruiser, the boat accommodates up to four guests in two cabins with one head, and the open cockpit and salon areas can comfortably seat ten people across extended wrap-around seating and a dining table that converts to additional sleeping or sunbathing space.
The layout centers on an open cockpit and salon combined into one social space, with forward-facing co-pilot seating alongside the helm. A distinctly wide companionway connects the galley directly to the cockpit, allowing the cook to remain part of the group while the design naturally exhausts cooking fumes topside. The galley includes a 29-liter freezer-fridge drawer and electric microwave. The two cabins feature engineered teak cabinetry, and the boat is finished in pebble grey hull with light sand cabin upholstery and silver grey canopy.
This boat comes equipped with a 16-inch glass cockpit multifunction display, Volvo Reactor 40 autopilot, Zipwake dynamic trim control, GMR Fantom 24 radar, and VHF 315 radio. Navigation and safety are supported by a searchlight with joystick control and a backup camera. Power and comfort systems include a ~4-kilowatt diesel generator with separate charger, approximately 450 watts of solar panels with app monitoring, 9-kilowatt defroster with hot air outlet, and air conditioning with multiple AC outlets throughout. Cabin lighting features dimmable mood lights on wooden rails. The transom carries two RGB underwater lights, and entertainment includes a standard audio system with amplifier and subwoofer upgrade. A long platform version extends the platform for additional deck space.
