1974 Bertram 31 Flybridge Cruiser

This 1974 Bertram 31 Flybridge Cruiser is a classic example of one of the most respected hull designs in its class. Built with solid fiberglass construction, the boat is known for its legendary ride quality and offshore capability. Twin gasoline MerCruiser inward engines provide 660 hp combined, powering a 30-foot cruiser with an 11-foot beam.

The boat has benefited from decades of continuous maintenance by reputable Great Lakes service yards, with extensive and well-documented service records spanning multiple decades. Work includes regular engine servicing—oil changes, tune-ups, cooling system maintenance, carburetor rebuilds, ignition upgrades, and charging system improvements. The hull has been refinished with Awlgrip paint and boot stripe work, with ongoing bottom paint maintenance. Fuel systems have been serviced, and the electrical system has been updated with new batteries and rewired as needed.

Interior and systems updates include head servicing, freshwater system work, bilge pump replacement, lighting improvements, and cabinetry repairs. Deck hardware, seating, rub rail sections, and scuppers have been addressed as needed. The boat reflects proactive ownership, with issues handled promptly rather than deferred. Annual commissioning and winterization have been performed throughout its history on the Great Lakes.
