About the CAVALIER 30 (CHEVERTON)

Sailpages Buyer's Take

The Cavalier 30 is a rare, heavy-displacement cruising sloop designed by David Cheverton and built by Wing on Shing in Hong Kong between 1966 and 1968. With only 6 hulls built, this model represents a distinct era of offshore-oriented design characterized by a full keel and substantial ballast.

Best for:
This boat is best suited for experienced coastal cruisers and conservative bluewater sailors who prioritize seakeeping and comfort over high-speed performance. Its heavy displacement and full keel make it ideal for those seeking a stable, safe platform for long-distance cruising rather than racing.
Bluewater capability:
With a displacement of 10976.0 lb and a capsize ratio of 1.65, the Cavalier 30 demonstrates strong inherent stability and offshore suitability. Its full/long keel design and high D/L ratio of 430.18 indicate a boat built for safe, comfortable passage-making in heavy weather.
Comparables:
Comparable boats include the Tartan 30 and the O'Day 30, which share similar production eras and heavy-displacement, full-keel characteristics. These vessels offer similar cruising comfort and offshore stability, making them direct functional equivalents for buyers seeking a robust 30-foot cruiser.
