About the NAUTICAL 56/60
The Nautical 56/60 is a substantial 56.0 ft ketch designed by S. Seaton & R. Warren and built by Nautical Development Corp. in 1980. With a displacement of 51000.0 lb and a comfort ratio of 42.16, this vessel represents a heavy, stable platform from a single production year.
- Best for:
- This boat is best suited for experienced coastal cruisers and those seeking a stable, heavy-displacement platform for protected waters, given its significant weight and beam.
- Bluewater capability:
- With a capsize ratio of 1.69 and a displacement of 51000.0 lb, the boat exhibits strong inherent stability and motion comfort, suggesting good offshore potential despite the lack of specific bluewater cruising records in the data.
- Comparables:
- Comparable vessels include other heavy-displacement ketches from the late 1970s and early 1980s, such as the Tartan 4400 or O'Day 38, which share similar conservative hull forms and cruising-oriented designs.
