Boat Description
The 2026 Harris Grand Mariner 250 SLEC is a 25-foot tritoon at the upper end of the Harris line, built on a three-tube chassis with a center lifting strake and full-length keels for a steadier, faster ride than a two-tube boat. The deck runs to plush lounge and recliner seating, an entertainment-center layout with a wet bar area, a powered bimini, and a wide swim platform, with a touchscreen helm and a full audio system. The three-tube setup carries a high-horsepower Mercury outboard, enough to pull skiers and tubes, not just cruise. The Grand Mariner is the boat you step up to when you want the room and the finish.
The third tube and high power matter on Flathead, where the afternoon wind builds real chop and a tritoon holds a steadier, drier ride across open water. Anchor it in a bay for a big group or run watersports off the back, then cruise home as the light drops over the Whitefish range. The Grand Mariner 250 SLEC is at Whitefish Marine. Call 406-862-8594 to see it.
