About the BREEHORN 37
Thanks to Aike van der Hoeff for providing information on this yacht.
The Breehorn 37 is a robust cruising sloop designed by Dick Koopmans Sr. and built by Breehorn, with production records indicating a single build year of 1980. This vessel offers a comfortable cruising platform with a displacement of 17196.0 lb and a beam of 11.61 ft, reflecting a design focused on stability and interior volume.
- Best for:
- This boat is well-suited for coastal cruisers and those seeking a stable, comfortable liveaboard or weekend cruiser, particularly given its high comfort ratio of 31.9 and spacious beam. It appeals to owners who value a proven, heavy-displacement hull form for relaxed cruising rather than high-performance racing.
- Bluewater capability:
- With a displacement of 17196.0 lb, a capsize ratio of 1.8, and a fin keel, the Breehorn 37 possesses the structural integrity and stability required for offshore passages, though its single-year production suggests a limited fleet history for long-term bluewater validation.
- Comparables:
- Comparable vessels include other late-1970s and early-1980s heavy-displacement cruising sloops such as the Cal 34 or O'Day 38, which share similar beam widths and displacement characteristics. These boats are comparable due to their focus on interior comfort, stability, and moderate sailing performance typical of the era's cruising designs.
