About the LONGBOW 31 (WESTERLY)
Aft cockpit. Same hull as BERWICK, PENTLAND & RENOWN. Available also as a ketch.
Designed by Laurent Giles and built by Westerly Marine Ltd. (UK) from 1972–1980, the Longbow 31 is a robust cruiser with 265 hulls produced. Its heavy displacement of 9400.0 lb and fin keel configuration reflect a design philosophy prioritizing stability and seakeeping over pure speed.
- Best for:
- This boat suits coastal cruisers and those seeking a comfortable, stable passage-making vessel, particularly owners who value the proven durability of Laurent Giles designs. It is well-suited for couples or small families who prioritize a secure motion and reliable systems over high-performance racing.
- Bluewater capability:
- With a displacement of 9400.0 lb and a capsize ratio of 1.8, the Longbow 31 demonstrates strong inherent stability and resistance to capsizing, making it highly suitable for offshore passages. Its fin keel and comfortable motion further support its reputation as a capable bluewater cruiser.
- Comparables:
- Comparable boats include the Westerly Comet and the Hallberg-Rassy 31, as they share similar heavy-displacement characteristics and offshore-oriented hull forms from the same era. The Longbow 31 also compares to the Tartan 31 in terms of beam and interior volume, though the Longbow offers a more refined finish typical of British builders.
