About the MAMBA 33
Designed by Bengt Karlsson and built by Mamba Boat AB in Sweden from 1985–1991, the Mamba 33 is a fractional sloop with a displacement of 9700.0 lb. While the exact number of hulls built is unknown, the vessel is characterized by a D/L ratio of 214.48 and a comfort ratio of 22.1, indicating a heavy, stable cruiser.
- Best for:
- This boat suits coastal cruisers and those seeking a comfortable, stable ride, as evidenced by its high comfort ratio and fractional sloop rig which offers manageable handling for couples or small families.
- Bluewater capability:
- With a capsize ratio of 2.02 and a displacement of 9700.0 lb, the Mamba 33 possesses the stability and mass required for offshore passages, though its fin keel design should be scrutinized for structural integrity.
- Comparables:
- Comparable boats include other Bengt Karlsson designs from the late 1980s, such as the Hallberg-Rassy 35 or the Nauticat 353, which share similar heavy-displacement characteristics and Scandinavian build quality.
