The Bostrom 31, frequently recognized by its succinct "B31" branding, represents a pivotal era of Scandinavian boatbuilding when fiberglass was beginning to replace timber as the primary medium for mass production. Designed by Bruno Boström in 1973, the vessel was conceived as a rugged offshore cruiser capable of navigating the demanding waters of the Baltic and North Seas. Over 1,000 units were produced between 1973 and 1988, marking it as one of the most successful 31foot designs of its generation. The boat’s profile is characterized by a traditional aesthetic, featuring a balanced masthead sloop rig and a hull that emphasizes seakindliness over outright racing speed. It is often cited as a more affordable, yet comparably robust, alternative to contemporaneous yachts from Albin or HallbergRassy.
