2026 Harris Grand Mariner 230

The 2026 Harris Grand Mariner 230 SL is a 23.75-foot aluminum pontoon powered by a Mercury Verado 300-horsepower supercharged four-stroke engine. Finished in Black Sapphire with Midnight Blue accents, it combines refined styling with serious performance. The boat comes equipped with the Performance Package 327, featuring triple 27-inch diameter pontoons with full-length center tube and lifting strakes for enhanced stability and lift. A 50-gallon integrated fuel tank supports extended range cruising, and the sport-tuned hull is designed for responsive handling across a range of water conditions.

The SL floorplan prioritizes comfort and entertainment with a rear-facing lounger, dual helm chairs, and wraparound seating throughout the deck. Premium soft-touch vinyl upholstery and woven teak-style flooring complement the layout. A Simrad NSX7 7-inch Solarmax HD touchscreen multifunction display integrates navigation via C-MAP Discover X charts with auto-routing and hazard avoidance, along with Simrad Companion App connectivity for extended control.

A manual-lift tower with integrated lighting tops the boat, while a Platinum sound system delivers high-fidelity audio for onboard entertainment. Standard equipment includes a Lillipad ladder, ski tow bar, removable table, cooler, and safety rails throughout.
