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.

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

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.

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 cracked off once it pipes up, 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

There is no condition where it falls away badly, which is worth something over a season of mixed weather.

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.

At 10 knots this design makes back more than its rating asks on the broad reach.

Rigging

Optima 101 rig and sail dimensions

A Optima 101 carries 11.75 m of mainsail hoist on a 4.07 m boom, a forestay 11.90 m above the deck and a 3.90 m bowsprit. Typical figures across the 6 boats measured under the current VPP, with the range each one spans.
