The Mamba 311 stands as a refined evolution of the Swedish cruising lineage, produced by BK Marin AB (later Mamba Boats) in Forshaga between 1982 and 1987. Designed by Bengt Karlsson, the 311 was developed as a direct successor to the Mamba 31, utilizing the same successful hull form but introducing a significantly modified deck mold and rig configuration. This model targeted the performancecruiser market of the early 1980s, offering the robust build quality characteristic of Scandinavian yards alongside a competitive handicap for regional racing. While the original Mamba 31 established the brand's reputation, the 311 addressed specific owner feedback by increasing interior volume and modernizing the sail plan, as evidenced by the lines seen in this technical drawing from Listings Port.
