About the MAMBA 34
Designed as an IOR 3/4 ton. Also available with a frac. sloop rig. An updated, more cruising oriented version called the MAMBA 341 was introduced in 1981.
The Mamba 34 is a Swedish-built cruiser designed by Rolf Magnusson and constructed by BK Marin (SWE) between 1978–1986, with a total production run of 100 hulls. Known for its robust construction and comfortable interior, this masthead sloop offers a balanced blend of performance and liveability for its era.
- Best for:
- This boat suits coastal cruisers and those seeking a comfortable, stable platform for weekend trips or extended near-shore voyages, particularly owners willing to invest in maintenance of its aging composite structures.
- Bluewater capability:
- With a displacement of 10803.0 lb and a capsize ratio of 2.04, the Mamba 34 possesses the heavy, stable hull form necessary for offshore passage-making, though its bluewater readiness depends heavily on the condition of its deck core and keel attachment.
- Comparables:
- Comparable boats include the Hallberg-Rassy 34 and the Nauticat 34, as they share similar Scandinavian design philosophies, heavy displacement characteristics, and target the same market of serious cruisers from the late 1970s and early 1980s.
