About the LAPWORTH 39
The Lapworth 39 is a rare, historic vessel designed by C. William Lapworth and built in 1959, with the exact number of hulls produced remaining unknown. As a 39.0 ft LOA masthead sloop with a displacement of 18000.0 lb, it represents a significant piece of mid-century yacht design history.
- Best for:
- This boat is best suited for collectors of historic yachts or owners seeking a unique, heavy-displacement cruiser with a 11.2 ft beam, rather than those looking for a high-performance racer or a mass-produced model with readily available parts.
- Bluewater capability:
- With a high displacement of 18000.0 lb, a low capsize ratio of 1.71, and a comfort ratio of 33.42, the Lapworth 39 exhibits strong inherent stability and motion comfort suitable for offshore passages, provided the hull integrity is verified.
- Comparables:
- Comparable boats include other 1950s-1960s heavy-displacement fin-keel sloops such as the O'Day 38 or early Catalina 30s, sharing similar era-specific construction methods and moderate sail area-to-displacement ratios (13.47).
