Comet 45
Comar · Andrea Vallicelli · 2003
Updated
The Comet 45 is a 13.72 m displacement racing yacht designed by Andrea Vallicelli and built by Comar, first launched in 2003. It races in Class A. Across the measured fleet it goes better than its own numbers promise, ahead of 31% of the designs it races against. It is at its best in light air and struggles to hold that once it blows.
Goes better than its own measurements promise, and does it better than 31% of the boats it races against.
32nd of 46 in its class.
This design has been found in real race results — 118 starts across 51 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.

Sharper round the buoys. Short courses reward acceleration and manoeuvring, and that is where this design makes its money.

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.
There is no obvious weak spot here. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is across the wind once the breeze fills, where it goes better than its measurements say it should, and by a margin worth having.
Where it pays
It falls short running deep in a strong breeze, giving away time it never gets back. That is a displacement hull working to its designed speed.
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. A bowsprit is standard across the fleet. Crew weight is declared around 690 kg.
Rigging
Comet 45 rig and sail dimensions
A Comet 45 carries 17.20 m of mainsail hoist on a 5.94 m boom, a forestay 17.95 m above the deck and a 6.52 m bowsprit. Typical figures across the 16 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 127 to 182 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.
