This 1975 Bertram 31 is a classic sportfishing yacht built on the deep-V hull design that defined the model. Twin Cummins diesel engines produce 540 horsepower combined, delivering a cruising speed of 25 knots and a top speed of 29 knots. The 31-foot hull, with an 11-foot beam, balances offshore capability with manageable handling.
The yacht accommodates one cabin with a single head. The cockpit is spacious and functional, suited for both fishing and cruising. Below deck, the cabin layout provides comfortable quarters for extended time on the water.
Recent work includes new main engine risers and turbos installed in 2023, replacement of belt tensioners and pulleys in 2024, and a fresh bottom job in 2025. The hull received new Awlgrip paint in 2022. The Cummins engines were installed in 2003 and continue to power the yacht.
