Updated
The Dehler 33 is a 9.99 m semi-displacement racing yacht designed by Judel/Vrolijk and built by Dehler, first launched in 1995. It races in Class C. Across the measured fleet it goes better than its own numbers promise, ahead of 59% of the designs it races against. It comes alive as the breeze builds, and gives time away in the light.
Goes better than its own measurements promise, and does it better than 59% of the boats it races against.
65th of 159 in its class.
This design has been found in real race results — 21 starts across 7 events — not only in measurement files.

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 is a boat that wants breeze. Give it a fresh day and long legs and it delivers more than it promised; in a drifter it is working uphill.
Where it gains
Its best ground is on a broad reach once it pipes up, where it does more than its size and sail area promise, and by a margin worth having. It holds that advantage downwind as well, so the gain is not down to one leg of the course.
Where it pays
There is no condition where it falls away badly, which is worth something over a season of mixed weather.
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 upwind.

The range each sail spans across the fleet.
Nearly all carry a folding propeller. Crew weight is declared around 520 kg.
Rigging
Dehler 33 rig and sail dimensions
A Dehler 33 carries 12.00 m of mainsail hoist on a 4.39 m boom, a forestay 11.90 m above the deck and a 4.18 m bowsprit. Typical figures across the 13 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 57 to 90 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.
