Spend less time managing the boat and more time actually using it across Tampa Bay, whether that’s a quick evening run or a full day moving between sandbars and nearshore fishing.

Many owners at this size start to feel the trade-offs—limited seating, cluttered layouts, or electronics that require too much attention. The Open 212 removes that friction with a layout that supports both fishing and family use without constant reconfiguration. The 250HP Mercury V8 provides straightforward, predictable power, so you’re not second-guessing range or performance when conditions shift. At the helm, the Garmin 12” display, integrated systems, and digital switching reduce the need to manage multiple controls. Everything is centralized and easy to understand, which shortens the learning curve and keeps your focus where it should be—on the water ahead. Seakeeper Ride actively adjusts the boat’s running attitude, improving comfort and visibility without manual trim adjustments, especially in Tampa Bay chop.

Seating is built for actual use, not just appearance. The premium dual helm chairs, fold-down rear seat, and convertible bow sunpad allow you to transition between cruising, sandbar stops, and fishing without moving cushions around or giving up space. Storage is placed where you need it—under gunwales, in the console, and beneath seating—so gear stays organized and accessible.

Fishing features like the aquarium livewell, high-speed pickup, and dedicated rod storage support serious use without interfering with family comfort. Washdowns and easy-clean surfaces reduce cleanup time at the end of the day.
