About the MAMBA 29
Designed by Jan & Harry Becker and built by BK Marin/MambaBoats (SWE) from 1980–1989, the Mamba 29 is a compact cruiser with a production run of 200 hulls. Its fractional sloop rig and fin keel configuration offer a balanced blend of performance and stability for its era.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a manageable size and fractional rig handling, though its relatively light displacement suggests it is best suited for protected waters rather than heavy offshore work.
- Bluewater capability:
- With a displacement of 7055.0 lb and a capsize ratio of 2.01, the Mamba 29 is generally considered suitable for coastal cruising rather than extended bluewater passages due to its lighter weight and lower comfort ratio of 21.53.
- Comparables:
- Comparable boats include the Catalina 27 and O'Day 28, which share similar fractional sloop rigs and target the same market of entry-level cruisers seeking easy single-handed or couple sailing.
