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

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 on the beat once it pipes up, where it goes better than its measurements say it should.
Where it pays
It falls short cracked off 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.

How they are set up
The range each sail spans across the fleet.
Nearly all carry a folding propeller. Crew weight is declared around 480 kg.
Rigging
Delphia 33 rig and sail dimensions
A Delphia 33 carries 12.85 m of mainsail hoist on a 4.10 m boom, a forestay 12.58 m above the deck. Typical figures across the 3 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 61 to 76 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.
