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.

Better the longer it gets. Boats that settle into a groove and hold it gain ground once the course stops turning.

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.

This one is at home going to windward. Windward-leeward courses give it more of what it is good at than a coastal race does.

Where it gains

Its best ground is on the beat when it blows, where it goes better than its measurements say it should, and by a margin worth having.

Where it pays

It falls short on a broad reach once it pipes up, 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

Swan 37 rig and sail dimensions

A Swan 37 carries 12.57 m of mainsail hoist on a 3.57 m boom, a forestay 14.10 m above the deck. Typical figures across the 6 boats measured under the current VPP, with the range each one spans.
