About the GRANADA 31
The GRANADA 939 appears similar but with a taller fractional rig.
Designed by Elvstrøm & Kjærulff and built by Gesten Glasfiber Bådeværft (DEN) from 1977–1982, the Granada 31 is a classic Danish cruiser with 750 hulls produced. Its moderate displacement of 7938.0 lb and comfort ratio of 21.79 suggest a balanced ride, though owners report significant structural maintenance needs typical of this era.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a comfortable, stable platform and are prepared for hands-on maintenance. It is less ideal for those seeking a turnkey vessel due to the high frequency of reported structural repairs.
- Bluewater capability:
- With a low capsize ratio of 2.01 and substantial ballast of 3627.7 lb, the hull form is inherently stable for offshore passages, though structural integrity of the deck and keel must be verified before bluewater use.
- Comparables:
- Comparable to other late-70s European fin-keel sloops like the Beneteau First 30 or Oyster 30, sharing similar dimensions and masthead sloop rigs. These boats offer similar performance profiles but may have different construction methodologies regarding deck cores.
