About the CAPE DORY 30K
(formerly listed as CAPE DORY 30 KETCH) Also available as a cutter. (CAPE DORY 30C).
The Cape Dory 30K is a classic cruising ketch designed by Carl Alberg and built by Cape Dory Yachts (USA) in 1976. With a build count of ? hulls, this vessel represents a specific iteration of Cape Dory's early production, characterized by its traditional full-keel design and heavy displacement.
- Best for:
- This boat is best suited for conservative coastal cruisers and those seeking a stable, comfortable passage-making experience, rather than high-performance racing or tight single-handed maneuvering.
- Bluewater capability:
- With a displacement of 10000.0 lb, a capsize ratio of 1.67, and a full/long keel, the 30K is well-suited for offshore cruising due to its inherent stability and seakeeping abilities.
- Comparables:
- Comparable boats include the Cape Dory 30 (sloop) and other Carl Alberg designs from the mid-1970s, as they share similar heavy-displacement hull forms and traditional construction methods.
