About the BRISE DE MER 34
The Brise de Mer 34 is a classic French cruising sloop designed by Finot and built by Le Guen-Hemidy in France between 1975 and 1984, with a total production of 32 hulls. This rare, lightweight vessel offers a distinct alternative to heavier displacement cruisers of its era, characterized by its fin keel and masthead sloop rig.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize ease of handling and moderate performance over heavy offshore endurance, particularly those comfortable with the maintenance demands of a 1970s fiberglass hull.
- Bluewater capability:
- With a low D/L ratio of 193.76 and a capsize ratio of 2.08, the Brise de Mer 34 is best suited for protected coastal waters rather than extended bluewater passages, as its light displacement offers speed but less inherent stability in heavy seas.
- Comparables:
- Comparable boats include the O'Day 35 and Cal 34, as they share similar era, length, and coastal cruising roles, though the Brise de Mer distinguishes itself with a significantly lighter displacement of 9921.0 lb compared to the heavier, more traditional designs of its American contemporaries.
