About the DEHLER 39 SQ
SQ = Speed and Quality. Same hull as the DEHLER 39 (1996), but with taller rig. Entirely different from the earlier DEHLER 39 CWS (van de Stadt).
The Dehler 39 SQ is a performance-oriented fractional sloop designed by Judel/Vrolijk and built by Dehler in Germany, with production records indicating a build year of 2004. With a displacement of 16755.0 lb and a comfort ratio of 24.32, this vessel balances speed with moderate seakeeping, though the exact total hulls built remains unverified in the source data.
- Best for:
- This boat suits active coastal cruisers and short-handed racers who prioritize sailing performance and modern fractional rig handling over heavy bluewater comfort.
- Bluewater capability:
- With a capsize ratio of 1.98 and a displacement of 16755.0 lb, the Dehler 39 SQ is suitable for protected coastal passages and short offshore trips, but its relatively light displacement and fin keel suggest it is not optimized for heavy-weather bluewater voyaging.
- Comparables:
- Comparable vessels include the Beneteau First 36.7 and the J/36, as they share similar fractional sloop rigs, lightweight displacement characteristics, and a focus on high-performance coastal cruising from the mid-2000s.
