About the COSTANTINI 30
The Costantini 30 is a rare, lightweight cruising sloop designed by Gilles Costantini and built in France between 1971 and 1976. With only 5 hulls constructed, this model represents a niche entry in the market, characterized by its specific dimensions and low production volume.
- Best for:
- This boat suits experienced sailors seeking a lightweight, responsive coastal cruiser with a masthead sloop rig, rather than heavy-displacement bluewater voyagers.
- Bluewater capability:
- With a displacement of 5952.0 lb and a capsize ratio of 2.19, the boat is relatively light for offshore work, suggesting it is better suited for protected coastal cruising than heavy-weather bluewater passages.
- Comparables:
- Comparable boats include other lightweight European designs from the early 1970s with similar displacement (5952.0 lb) and beam (9.91 ft), such as the O'Day 30 or early Catalina 30s, though the Costantini's extreme rarity makes direct comparisons difficult.
