Spend less time adjusting your setup and more time running confidently across Tampa Bay with a boat that keeps everything working the way it should.

Most owners at this level are done managing compromises—whether that’s inconsistent control at the helm, unreliable power management, or setups that don’t transition cleanly between fishing and family use. The 321 Heritage removes that friction with systems that stay predictable and a layout that works without constant adjustment.

Yamaha Helm Master brings precise joystick control and integrated steering, making docking, positioning, and tight maneuvering far more controlled and repeatable. That translates directly into less stress around the dock and more confidence in changing conditions. The Mastervolt charging system keeps onboard power consistent, so electronics, pumps, and accessories operate without interruption throughout the day. A factory-installed trolling motor harness simplifies adding or running a trolling motor, reducing rigging complexity and keeping your setup clean and ready.

Finished in Ice Blue with a matching Ice Blue hull bottom, this configuration maintains a uniform look that’s easier to care for over time while staying sharp on the water.

Thunder Marine supports this ownership with direct service access and a team that understands how this boat is used in St. Pete, Clearwater, and Sarasota. That means quicker answers, less downtime, and a clearer path to consistent use.
