This is the kind of boat that lets you leave the dock knowing the day will unfold smoothly—comfortable for the family, capable for fishing, and easy to manage in Tampa Bay conditions.
 If your current boat forces tradeoffs between entertaining, running offshore, and relaxing at the sandbar, the Heritage 231 replaces those compromises with a single, balanced platform that does all three without extra effort.

At 23'4" with a 20° deadrise, the Heritage 231 delivers a confident ride through afternoon chop while still staying efficient and predictable around St. Pete, Clearwater, and Sarasota. The single Yamaha F300 provides straightforward power and service simplicity, while the 106-gallon usable fuel capacity supports full-day plans without constant range calculations. Seakeeper Ride actively manages pitch and roll, reducing fatigue and helping everyone stay comfortable underway.

At the helm, the Garmin 12" display, VHF, and integrated digital switching reduce clutter and decision-making. Everything is visible, reachable, and intuitive, which shortens the learning curve and keeps attention outside the boat. Seating is arranged to adapt—forward lounge with table and sun pad, dual helm chairs with bolsters, and a convertible aft bench—so the boat works equally well drifting, cruising, or sitting still.

Storage, livewells, freshwater, and a porcelain head are all integrated without crowding the deck. That matters when boating shifts from an occasional outing to a regular part of your schedule.
