About the GIB'SEA 31
Fin or Keel/centerboard versions available.
The Gib'Sea 31 is a robust cruising sloop designed by Joubert/Nivelt and built by Gibert Marine in France, with production records indicating a build year of 1979. With a displacement of 8800.0 lb and a comfort ratio of 22.03, this vessel is engineered for stability and seakeeping rather than high-speed planing.
- Best for:
- This boat is best suited for coastal cruisers and those seeking a comfortable, stable platform for offshore passages, given its heavy displacement and fractional sloop rig.
- Bluewater capability:
- With a low capsize ratio of 1.98 and a high D/L ratio of 209.44, the Gib'Sea 31 demonstrates strong inherent stability and resistance to capsizing, making it well-suited for bluewater cruising.
- Comparables:
- Comparable vessels include the Hallberg-Rassy 31 and the Tartan 31, as they share similar heavy-displacement characteristics, fractional rigs, and a focus on safe, comfortable offshore cruising from the late 1970s.
