The Bostrom B31 is a quintessential example of Scandinavian yacht design from the 1970s, representing a period when Swedish boatbuilding prioritized seaworthiness and structural integrity over maximum interior volume. Designed by Bruno Boström, the B31 was produced in significant numbers—estimated at over 1,000 hulls—making it one of the most successful 31footers in Northern Europe. It was uniquely offered both as a factoryfinished yacht and as a highquality kit for amateur completion, a factor that has led to a wide variance in interior finish quality across the secondary market. The yacht’s aesthetic is defined by its elegant, narrow beam and a distinctive reverse transom that gives it a sleek, timeless profile. Despite its age, the B31 remains a popular choice for coastal cruising and even offshore passages, often cited by the B31klubben as a reliable vessel for the demanding conditions of the Baltic Sea.
