2025 Harris Grand Mariner 230

The 2025 Harris Grand Mariner 230 is a 23-foot aluminum pontoon powered by a 300-horsepower Mercury V8 Verado. Built for both cruising and watersports, it features a 1,000-pound-rated ski tow bar, an upgraded Lillipad Easy Step ladder, and a fold-down in-water swim seat on the port side.

The open layout centers on a dual helm station with swivel, slide, and recline chairs positioned at the raised helm. The Deluxe Tech 2 Package brings twin Simrad displays, a JL Audio system with tower speakers, and full RGB lighting. Mercury's digital throttle system is integrated at the helm. Additional seating and lounging areas include a flip-up entertainment table on the port side and a table in the bow, with a movable cooler ottoman adding flexibility.

Storage and conveniences are integrated throughout: USB and USB-C charging ports, wireless chargers, and cupholders are distributed across the boat, with dedicated space under and behind seats. A center locker offers substantial storage capacity, and a dedicated trash compartment is included. An Ion power folding tower with dual bimini tops provides weather protection and shade. The interior features a Chestnut pillow-top finish, while the exterior is finished in Midnight Blue with a Metallic White accent stripe.
