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.

Soft conditions suit it. In the light it does more than its numbers promise, and gives some of that back when the wind arrives.

Where it gains

Its best ground is cracked off in light air, where it outruns what it looks like on paper, 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 across the wind 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.

Rigging

Elvstr rig and sail dimensions

A Elvstr carries 12.28 m of mainsail hoist on a 3.80 m boom, a forestay 11.00 m above the deck. Typical figures across the 2 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 68 to 78 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.
