Built by Harris in 2027, the Grand Mariner 250 is an 8.53-metre motor vessel that combines high-performance engineering with comfortable entertaining spaces. This flagship pontoon delivers a balanced package of capability, stability and social hosting designed for buyers seeking a capable day boat with real punch and refinement.
Powered by a Mercury 425L Verado V10 engine with Digital Throttle & Shift and Power Assist Steering, this Grand Mariner stands on a heavy-duty triple 27-inch tube chassis with lifting strakes and full-length keels for precise tracking and exceptional buoyancy. The helm features dual high-back contoured seats on a raised platform with rearview mirror and removable windscreen. Onboard you'll find an electrically operated power lift ion tower paired with a black Bimini top and high-output tower speakers, complemented by an attachable double Bimini for extended shade. The social layout includes a single rear-facing lounger with dual helm seating, all wrapped in Luxe Chestnut Brown upholstery with heat-resistant Cool Touch technology. Additional features include full-deck teak-patterned vinyl flooring, a luxury woodgrain sport table with chaise end flip-up table, stainless steel safety railing, in-floor storage with standard and recycling trash options, and an integrated C-Zone digital lighting system controlling full-spectrum RGB LEDs throughout interior and exterior spaces.
This vessel is well-suited to buyers seeking an entertaining platform for weekend family outings, water sports and social gatherings. The robust engine, tuning stability and generous shade and audio provisions make it an engaging choice for those who value both spirited performance and relaxed hosting comfort on protected and moderate waters.
