What the fleet has seen

The Dehler Yachts 31, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Dehler Yachts 31 is a fractional sloop with a fin keel and spade rudder, designed by E. G. Van de Stadt and built by Dehler from 1984 to 1994. It measures 9.4 meters LOA, with a 3.1-meter beam, 1.4-meter draft, and 3200 kg displacement. The Dehler 31 has a sail area to displacement ratio of 19.3 and a comfort ratio of 18.9. Its design, VDS #392, also produced variants such as the Dehler 32 and Duetta 94. A Dehler 39 JV owner, based in Storsham, Hurum, prioritizes robust construction, inspecting keel attachments, chainplates, and mast support systems when evaluating used sailboats.1:35 This owner replaced the standard mainsheet system with a T-track arrangement to simplify shorthanded sailing and eliminated the need for a large genoa.2:57
