SANTARELLI · Santarelli · 1982

Updated

The Asso 99 is a 9.96 m planing racing yacht designed by Santarelli and built by SANTARELLI, first launched in 1982. It races in Class B. Across the measured fleet it goes better than its own numbers promise, ahead of 16% of the designs it races against. It comes alive as the breeze builds, and gives time away in the light.

Updated — Race Edge up from 1 to 14. More boats of this design have been measured, and the figure now rests on a larger fleet. The gain shows most in light and medium air.

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.

Round the buoys, or offshore

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

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.

The stronger it blows, the better this design looks. On a windy coastal course it is in its element; on a light-air windward-leeward it has to be sailed well to hold on.

Where it gains

Its best ground is off the wind once it pipes up, where it goes better than its measurements say it should, and by a margin worth having. 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 in the light stuff, giving away time it never gets back. A planing hull rarely rewards a drifter: there is not enough pressure to get anything out of 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.

Rigging

Asso 99 rig and sail dimensions

A Asso 99 carries 11.25 m of mainsail hoist on a 4.15 m boom, a forestay 9.90 m above the deck and a 5.60 m bowsprit. Typical figures across the 17 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 52 to 83 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.
