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 design is even-tempered. It rewards preparation and crew work more than it rewards picking the right day.

Where it gains

Its best ground is across the wind in the light stuff, where it does more than its size and sail area promise, and by a margin worth having.

Where it pays

It falls short on the run when it blows, giving away time it never gets back. That is a displacement hull working to its designed speed.

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.

How they are set up

The range each sail spans across the fleet.

Mainsail61 m² – 66 m²

Gennaker154 m² – 213 m²

Nearly all carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 930 kg.

Rigging

X4.6 rig and sail dimensions

A X4.6 carries 17.90 m of mainsail hoist on a 6.15 m boom, a forestay 18.54 m above the deck and a 6.06 m bowsprit. Typical figures across the 7 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 154 to 213 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.
