A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Level across both. Plenty of designs fall away once the course gets long — a light hull that thrives round the cans can struggle through a night at sea. This one does not.

Where it wins and where it pays
Every boat is judged against its own measurements — length, weight, sail area. The quicker those say it should be, the more it has to deliver just to break even. Going fast is not enough: it has to go faster than its own numbers promised.
This design is even-tempered. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is to windward once it pipes up, where it outruns what it looks like on paper.
Where it pays
It falls short off the wind in a strong breeze, giving away time it never gets back. That is weight that has to be driven rather than released.
Above the line it delivers more than promised and gains on the fleet. Below, it falls short. Move the wind: plenty of boats sit on one side in the light and the other when it blows.
Full width is 0.4 kn either way.
At 10 knots this design makes back more than its rating asks on the beam reach.

Rigging
Dehler 34 (Stadt) rig and sail dimensions

Rig
Sails
The spinnaker spreads widest of all — 54 to 62 m² depending on bowsprit and set-up. Before ordering a sail, read the figure on your own measurement record rather than the typical one for the design.
