About the FINNGULF 331
Also called FINNGULF 33.
The Finngulf 331 is a fractional sloop designed by Karl-Johan Stråhlmann and built by Finngulf, with production records indicating a build year of 2003. While the exact total hull count is not definitively established in the available data, this model represents a specific era of Scandinavian boatbuilding characterized by robust construction and efficient sail plans.
- Best for:
- This vessel is well-suited for coastal cruisers and weekend sailors who prioritize a manageable 33-foot footprint with a fractional rig for easier single-handed handling. Its moderate displacement and comfort ratio suggest it offers a stable, dry ride suitable for protected waters and short offshore passages.
- Bluewater capability:
- With a displacement of 10979.0 lb and a capsize ratio of 1.95, the Finngulf 331 demonstrates adequate stability for coastal cruising, though its relatively light displacement and fin keel configuration suggest it is better suited for protected waters than heavy offshore passage-making.
- Comparables:
- Comparable boats from this era include the Beneteau First 33 and the Nauticat 33, which share similar fractional sloop rigs and target the same market of performance-oriented coastal cruisers. These models offer similar beam and draft characteristics, providing a benchmark for interior volume and sailing dynamics.
