1973-2023 Bertram 31 Flybridge Cruiser

2023 Refit!!

This Bertram 31 Flybridge Cruiser was professionally refit in 2023 and repowered with twin Yamaha four-stroke outboards equipped with fly-by-wire controls and steering at both the upper and lower helm stations.

The refit was completed to a high standard, with most major systems replaced or upgraded. The Yamaha Helm Master EX system includes joystick controls, control binnacles, and integrated autopilot. The flybridge features new upholstery, a bench seat behind the helm, a new Eisenglass enclosure, and Garmin electronics. The lower helm station is similarly equipped with Garmin electronics and Yamaha controls. A forward-looking SIONYX camera is also integrated with the Garmin system.

The spacious cockpit offers plenty of room for fishing and watersports. Features include a livewell, large fish boxes, ample storage, easy bilge access, and convenient access to fuel filters for simplified maintenance.

Check out this page from history and enjoy its many improvments and upgrades.
