About the CT-56
The CT-56 is a substantial cruising ketch designed by Robert Perry and built by Ta Chaio Shipbuilding Co. in Taiwan during 1986. With a displacement of 61688.0 lb and a comfort ratio of 51.85, this vessel represents a heavy-displacement, full-keel design intended for serious offshore passage-making.
- Best for:
- This boat is best suited for experienced bluewater cruisers who prioritize seakeeping and comfort over high-speed performance, particularly those seeking a stable platform for long-distance offshore travel.
- Bluewater capability:
- With a capsize ratio of 1.57 and a D/L ratio of 312.52, the CT-56 exhibits strong inherent stability and motion comfort, making it highly capable for offshore cruising.
- Comparables:
- Comparable vessels include other Robert Perry designs from the late 1980s, such as the Cal 40 or similar full-keel ketches, due to the shared emphasis on traditional hull forms and heavy displacement.
