The 1974 Bertram 31 is a classic flybridge cruiser built on a deep-V fiberglass hull designed to handle rough offshore conditions. Twin Volvo diesel engines rated at 460 horsepower deliver a cruising speed of 18 knots with a top speed of 32 knots, balancing fuel efficiency with capable performance for fishing or extended cruising.
The boat accommodates two cabins and one head. The main deck features a large cockpit measuring 10 by 9 feet, well-suited for fishing or entertaining. The flybridge offers elevated sightlines and helm controls, while the cabin area provides comfortable sleeping quarters and interior living space for longer passages.
Built during the model's inaugural year, this Bertram represents the design that established the 31 as a durable, seaworthy platform favored for both recreational and commercial fishing work. The boat's rugged construction and straightforward layout have proven their longevity, with examples from this era remaining in active service.
