2026 Harris Grand Mariner 230

The 2026 Harris Grand Mariner 230 is a 23-foot aluminum cruiser powered by a single 350-horsepower Mercury V10 Verado engine with Digital Throttle & Shift and Power Assist Steering. Built on a Performance Level 3 triple-tube chassis featuring twin 25-inch outer tubes and an oversized 27-inch center tube, the boat combines a deep-V hull design with lifting strakes and a full-length keel to deliver stable, level running through rough water while allowing sharp, aggressive cornering. The package includes a heavy-duty stainless steel ski tow bar for watersports.

The helm and social layout centers on dual ultra-luxury high-back captain and first-mate seats with swivel bases, armrests, and deep foam cushioning, paired with a single rear-facing lounger upholstered in Luxe Chestnut Brown cool-touch vinyl. A raised helm platform gives the captain clear sightlines over forward passengers. The entire deck is finished in durable Desert Beige Seagrass woven vinyl with non-slip texturing. An upgraded black acrylic table provides dockside space, while an in-floor storage trash can keeps the interior clean. A wrap-around stainless steel transom railing ensures safety at the rear lounger while underway.

The removable windscreen and Ion Power Lift Tower—electronically actuated and finished in black—raise or collapse at the helm for bridge and boat slip clearance. The tower integrates a black Bimini top and high-output tower can speakers. Docking is simplified with factory-integrated high-intensity lights, quick-release fender systems, and two additional 8.8-inch diameter fenders with quick-attach straps. The exterior carries a commanding Midnight aesthetic: Deep Black Sapphire Metallic panels with Black Matte accent stripe and Black Edition powder-coated rails.

Electronics include a premium multi-zone marine audio system with tower speakers, a full C-Zone digital lighting network controlling interior and exterior RGB LEDs across cupholders, seat bases, floor lanes, and underwater lines, a wireless phone charging dock, and advanced digital touchscreen displays at the helm.
