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

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 when the breeze is soft, where it goes better than its measurements say it should. It holds that advantage running deep as well, so the gain is not down to one leg of the course.
Where it pays
It falls short cracked off when it blows, 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 upwind.

Rigging
Comet 105 rig and sail dimensions
A Comet 105 carries 11.35 m of mainsail hoist on a 3.55 m boom, a forestay 13.05 m above the deck. Typical figures across the 7 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 67 to 77 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.
