About the JPK 40
Additional water ballast. 2x 750 l tanks.
Designed by Jacques Valer and built by JPK Composites (FRA) from 2007–2021, the JPK 40 is a performance-oriented cruising sloop with a fractional (9/10) rig. With a displacement of 10141.0 lb and a D/L ratio of 70.95, it balances speed with comfort, though the exact number of hulls built is not specified in the available data.
- Best for:
- This boat suits active coastal cruisers and short-handed sailors who prioritize sailing performance and modern ergonomics over heavy bluewater provisioning.
- Bluewater capability:
- With a capsize ratio of 2.61 and a comfort ratio of 11.55, the JPK 40 is capable of offshore passages but is best suited for protected waters and short bluewater trips rather than extreme heavy-weather voyaging.
- Comparables:
- Comparable to the Beneteau First 40.7 and Nauticat 40, as these contemporaries share similar fractional rigs, lightweight displacement, and a focus on performance cruising.
