2026 Harris Grand Mariner 230

The 2026 Harris Grand Mariner 230 is a 23-foot pontoon powered by a single Mercury 350 hp V10 Verado engine with Digital Throttle & Shift and Power Assist Steering. The boat sits on a Performance Level 3 chassis with triple 27-inch tubes, lifting strakes, and a full-length keel. Protective plating guards the tubes during docking and from submerged debris. The larger tube diameter provides greater weight capacity and stability in rougher conditions than standard pontoons.

The deck features a power-folding Ion tower with integrated speakers, a double bimini shade system spanning the full width, an aft swim seat at the waterline, and a ski tow bar for watersports. The exterior combines Midnight Blue with Black Edition powder-coated railings. Inside, the layout includes a single rear-facing lounge, dune-colored furniture with onyx accents, coastal bamboo flooring, a woodgrain luxury sport table, an upgraded black acrylic table, a chaise flip-up table, and an ultra luxury high-back helm seat raised for clear visibility.

The helm integrates C-Zone digital switching for interior and exterior RGB lighting control, dual touchscreen displays, integrated GPS, wireless charging, and an upgraded steering wheel with a removable windscreen and wide-angle rearview mirror for monitoring skiers. This boat is new for 2026.
