This boat is for owners who want long days on Tampa Bay, smooth runs offshore, and effortless hosting at the sandbar—without juggling multiple compromises.

The Heritage 321 replaces the common tradeoffs of ride comfort versus fishability, or family space versus offshore confidence. With a deep 23° deadrise, Seakeeper Ride control, and a wide 10'10" beam, it delivers a controlled, predictable ride while keeping everyone comfortable at rest. That balance matters when your boating day shifts from a morning run offshore to an afternoon anchored off Egmont or a sunset cruise back through St. Pete.

Twin Yamaha F350 outboards provide straightforward power management and redundancy, reducing stress on longer runs and making docking predictable. The Garmin 16" dual-display helm consolidates navigation, sonar, and system controls into a clean layout that shortens decision time underway. Multiple livewells, macerated fish boxes, and organized deck storage support serious fishing days, while the electric bow sun deck/table, mezzanine seating, and full head keep non-fishing days equally rewarding.

This Heritage 321 is configured to simplify how you use your time on the water, not complicate it with constant adjustments or workarounds.
