This boat is built for owners who want to cover more water in Tampa Bay without adding complexity or giving up comfort. The Open 232 replaces the common compromise between fishability and family use with a layout that works equally well for early-morning runs offshore, sandbar afternoons near Shell Key, or cruising between St. Pete and Clearwater.

With a true 23-foot platform, a 20° deadrise, and Seakeeper Ride for active trim control, this hull stays composed when conditions change. The single Yamaha 300 delivers strong, predictable power without the added service overhead of twins, keeping ownership straightforward. A 106-gallon usable fuel capacity supports longer days on the water without constant range anxiety. Garmin electronics, digital switching, and integrated helm ergonomics reduce workload so time underway feels calm and intentional.

Comfort is addressed without wasting space. The bow converts easily between seating and lounging, the console includes real storage and head access, and cockpit seating supports both fishing and family use. Washdowns, livewell placement, and deck storage are laid out for efficiency rather than show.

Thunder Marine brings clarity to the ownership experience, from delivery setup to long-term service access. This is a boat designed to be used often, not managed carefully.
