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.

It does most things without giving much away. It rewards preparation and crew work more than it rewards picking the right day.

Where it gains

Its best ground is running deep in a working breeze, where it goes better than its measurements say it should. It holds that advantage on the beat as well, so the gain is not down to one leg of the course.

Where it pays

It falls short cracked off 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

Show 34 rig and sail dimensions

A Show 34 carries 12.05 m of mainsail hoist on a 3.31 m boom, a forestay 13.34 m above the deck. Typical figures across the 4 boats measured under the current VPP, with the range each one spans.
