About the DUETTA 86 (DEHLER)
The Dehler Duetta 86 is a compact, performance-oriented masthead sloop designed by Van de Stadt and built by Dehler Yachts in Germany in 1979. With a displacement of 6720.0 lb and a beam of 9.68 ft, this vessel represents a specific era of German yacht building, though the exact total hulls built is unknown.
- Best for:
- This boat suits coastal cruisers and weekend racers who prioritize speed and agility over heavy offshore comfort, given its low D/L ratio of 159.94 and moderate comfort ratio of 18.66.
- Bluewater capability:
- With a capsize ratio of 2.06 and a fin keel with a max draft of 5.18 ft, the Duetta 86 is best suited for coastal and nearshore cruising rather than extended bluewater passages.
- Comparables:
- Comparable vessels include other late-1970s European performance cruisers like the Beneteau First 28 or Oyster 28, which share similar dimensions and a focus on sailing performance over heavy displacement.
