Not verified. On planing hulls this score has no match in the race results we hold: designs scoring the same win anywhere from one race in ten to seven in ten. Read it as what the measurements say, not as a ranking.
This design has been found in real race results — 122 starts across 57 events — not only in measurement files.

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

Better the longer it gets. Boats that settle into a groove and hold it gain ground once the course stops turning.

Speed in knots at 20 knots of true wind. Green marks the angles that pay: the closest useful beat and the deepest run worth sailing.
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.
It needs pressure to show what it can do. 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 off the wind once it pipes up, where it outruns what it looks like on paper, 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
It falls short on the beat once it pipes up, giving away time it never gets back. That is a hull that wants to get up and go, and needs pressure to do it.
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 2.4 kn either way.
At 10 knots this design makes back more than its rating asks on the beam reach.

How they are set up
The range each sail spans across the fleet.
Most run a fixed propeller. A bowsprit is standard across the fleet. Crew weight is declared around 360 kg.
Rigging
Dehler 30 OD rig and sail dimensions
A Dehler 30 OD carries 12.00 m of mainsail hoist on a 3.90 m boom, a forestay 12.21 m above the deck and a 5.44 m bowsprit. Typical figures across the 19 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 98 to 110 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.
