About the FINNGULF 37
Shallow Keel Draft: 1.75m 5.7' Ballast: 2480kg 5470lbs.
The Finngulf 37 is a fractional sloop designed by Karl-Johan Stråhlmann and built by Finngulf, with production records indicating a build year of 2004. While the exact total hull count is unspecified in the available data, the vessel is characterized by a displacement of 14330.0 lb and a comfort ratio of 25.21, suggesting a stable, motion-moderating platform.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a comfortable, stable ride over high-performance racing metrics, supported by its moderate SA/D ratio of 18.94 and fractional rig.
- Bluewater capability:
- With a low capsize ratio of 1.89 and a D/L ratio of 181.13, the Finngulf 37 exhibits strong offshore stability characteristics, though its bluewater readiness depends heavily on the condition of its fin keel and rigging.
- Comparables:
- Comparable vessels include other Scandinavian-designed cruising sloops from the early 2000s with similar displacement and beam, such as the Nauticat 36 or Beneteau 373, which share a focus on interior volume and ease of handling.
