2027 Harris Grand Mariner 250 SLDH

The 2027 Harris Grand Mariner 250 SLDH is a 25-foot pontoon powered by a Mercury 425L Verado V10 outboard with dynamic steering and power assist steering. The boat features a three-tube aluminum chassis with 27-inch diameter tubes, strakes, and metal jacket tube protection. Construction is fiberglass with a black powder-coat aluminum fence.

The single-level floor plan includes dual helm stations with ultra-luxury high-back seats in cool-touch chestnut brown upholstery and onyx accents. The raised helm provides commanding visibility. Interior appointments include chestnut teak flooring, in-floor storage with lidded compartments, and a woodgrain luxury sport table with flip-up chaise end. An onyx-accented cool chest sits nearby for convenience.

Technology and comfort features encompass a C-Zone control system for interior and exterior lighting, an NSX15 ultrawide display with integrated lighting package, JL Platinum speakers including tower-mounted cans, power-assist steering, and a ski tow bar in stainless steel. The black manual-lift Fusion Ultra tower is fitted with black bimini support. Additional deck storage, a trash can, and extra fenders round out the practical setup.
