About the DUETTA 94 (DEHLER)
VDS #392. See DEHLER 31. Shallow draft: 3.6'/1.1m
Designed by E. G. van de Stadt and built by Dehler (GER) from 1984–1994, the Duetta 94 is a compact fractional sloop with a displacement of 7055.0 lb. While the exact hulls built count is unknown, the fleet is characterized by a consistent build period and a mix of Yanmar and Volvo Penta engines.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a manageable 30.84 ft LOA and a 4.75 ft max draft for access to shallow harbors. Its 18.92 comfort ratio suggests it is well-suited for those seeking a stable ride without excessive motion.
- Bluewater capability:
- With a capsize ratio of 2.12 and a D/L ratio of 220.31, the boat is designed for coastal and nearshore cruising rather than heavy offshore passage-making. Its fin keel and moderate ballast ratio of 2865.7 lb indicate stability suitable for protected waters but limited for extreme offshore conditions.
- Comparables:
- Comparable boats include other 30-foot fractional sloops from the 1980s, such as the Beneteau First 30 or O'Day 302, which share similar fractional rig configurations and coastal cruising roles. The Duetta 94 distinguishes itself with German build quality and a slightly heavier displacement relative to its length.
