About the JOEMARIN 34
Also known as the LOHI 34.
The Joemarin 34 is a Finnish-built cruising sloop designed by Hans Groop and constructed by Joemarin OY in 1973. With a build count of ? hulls, this vessel represents a specific era of European boatbuilding characterized by robust construction and traditional design principles.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who prioritize a comfortable, stable ride over high-performance racing metrics. Its moderate displacement and comfort ratio suggest it is ideal for those seeking a manageable, safe platform for nearshore exploration.
- Bluewater capability:
- With a displacement of 12000.0 lb and a capsize ratio of 1.81, the Joemarin 34 demonstrates strong inherent stability and offshore potential, though its single production year and limited build count suggest a niche presence in the bluewater market.
- Comparables:
- Comparable vessels include other 1970s European fin-keel sloops such as the Hallberg-Rassy 34 or the Nautor's Swan 36, which share similar displacement ranges and cruising-oriented hull forms. These boats offer similar balance between seaworthiness and ease of handling for short-handed crews.
