Beneteau 331
Description
The Beneteau Oceanis 331 (1998–2001, ~500 units built) is a coastal cruiser designed by Groupe Finot, emphasizing comfort and ease for families or charters. It shares its hull with the racier First 331 but prioritizes spaciousness and simplicity. Known for its "big-boat feel" in a compact 34-foot package, it’s ideal for weekend cruising or short coastal hops, with a CE Category A ocean rating but best suited for protected waters (capsize screening ~2.0).

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them. You should take the same precautions, especially when the data is not from Sailrite.
