This boat is built for owners who want a single platform that handles family time, sandbar days, and serious fishing around Tampa Bay without constant setup changes or second-guessing conditions. Many experienced owners feel boxed in by smaller center consoles that run out of space, comfort, or confidence as plans evolve during the day. The Heritage 231 replaces those compromises with a layout that stays balanced whether you’re cruising St. Pete to Egmont, drifting offshore, or settling in at the sandbar.

At just over 23 feet with a wide 8’6” beam and a 20° deadrise, the hull is designed to stay predictable in Tampa Bay chop while remaining efficient and easy to manage at the dock. A single outboard setup keeps operation straightforward while still allowing up to 300 horsepower for confident acceleration and range planning. With seating for up to 12, dual aft livewells, integrated freshwater washdown, and multiple coolers built into the layout, the boat transitions smoothly from fishing to family use without tearing the cockpit apart.

Electronics and helm systems are fully integrated, reducing clutter and learning curves. Garmin navigation, digital switching, and Seakeeper Ride work together to reduce workload underway, especially when conditions change quickly. Storage is intentional, with insulated bow compartments, under-gunwale rod racks, and dedicated anchor and tackle spaces that keep gear secure and decks clear.

Thunder Marine delivers this Heritage 231 as a complete, ready-to-use package for Tampa Bay boating, not a checklist you have to finish later. From walkthrough to delivery and long-term service, the goal is to keep ownership simple and predictable.
