About the HARSTAD 31
The HARSTED 31 came from the same mold as those used to produced the larger models from Clipper Marine (30-32).
The Harstad 31 is a rare, heavy-displacement ketch designed by W.I.B. Crealock and built by Harstad Trawler Company (USA) between 1975 and 1976, with only 6 hulls produced. Its authoritative specifications include a displacement of 8000.0 lb, a beam of 8.0 ft, and a max draft of 3.5 ft, reflecting a robust, slow-cruising platform.
- Best for:
- This boat suits experienced coastal cruisers and bluewater adventurers who prioritize seaworthiness and comfort over speed, particularly those willing to manage a rare, low-production vessel with specialized maintenance needs.
- Bluewater capability:
- With a displacement of 8000.0 lb, a capsize ratio of 1.6, and a full/long keel, the Harstad 31 is well-suited for offshore cruising, offering exceptional stability and motion comfort in heavy seas.
- Comparables:
- Comparable boats include other Crealock designs like the Island Packet 32 or Valiant 32, which share similar heavy displacement, full keels, and ketch rigs aimed at safe offshore passage making.
