About the FINN FLYER 31
IOR 1/2 TON. Purpose built 1/2 ton racer was STILL 900 (1984? - 4 built.)
Designed by Eivind Still and built by Polar Yacht (FIN) from 1980–1990, the Finn Flyer 31 is a fractional sloop with a displacement of 7260.0 lb and a comfort ratio of 18.4. While the exact hulls built count is unknown, owner reports highlight a robust platform that requires vigilant maintenance of structural components.
- Best for:
- This boat suits coastal cruisers and those seeking a comfortable, stable platform with a 10.5 ft beam and 24.8 ft LWL, particularly owners willing to manage specific structural maintenance tasks.
- Bluewater capability:
- With a low capsize ratio of 2.17 and a D/L ratio of 212.49, the Finn Flyer 31 demonstrates strong offshore potential, though its bluewater readiness is contingent on addressing critical structural integrity issues.
- Comparables:
- Comparable to other 1980s European fin-keel cruisers with similar displacement and fractional rigs, it offers a balance of performance and comfort that rivals contemporary designs from the same era.
