2026 Harris Grand Mariner 270

The 2026 Harris Grand Mariner 270 is a 27-foot tritoon pontoon built on an aluminum triple-tube hull. It pairs a single 425-horsepower Mercury engine with a redesigned profile featuring sweeping lines and a sloped silhouette. The boat is built for both cruising comfort and watersports performance.

The cabin area centers on soft-touch vinyl seating and upholstered furniture. Navigation and helm control integrate a C-Zone digital system with Simrad touchscreen displays, typically paired units. Entertainment comes from a JL Audio premium sound system, while integrated lighting packages—including RGB accent lighting—run throughout the boat.

The pontoon accommodates day-boating and family outings without sleeping cabins. Equipment includes the helm electronics, audio system, and interior lighting as described.
