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.

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 in light air, where it outruns what it looks like on paper, and by a margin worth having.

Where it pays

It falls short off 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.

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

Mainsail31 m² – 51 m²
Headsail40 m² – 55 m²

Nearly all carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 640 kg.

Rigging

X-402 rig and sail dimensions

A X-402 carries 14.00 m of mainsail hoist on a 4.02 m boom, a forestay 15.91 m above the deck and a 4.81 m bowsprit. Typical figures across the 5 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 97 to 125 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.
