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 on the beam in light air, where it goes better than its measurements say it should, and by a margin worth having. It holds that advantage downwind as well, so the gain is not down to one leg of the course.

Where it pays

It falls short off the wind in a strong breeze, 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.

Nearly all carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 380 kg.

Rigging

Finngulf 33 rig and sail dimensions

A Finngulf 33 carries 12.93 m of mainsail hoist on a 4.48 m boom, a forestay 13.75 m above the deck and a 3.75 m bowsprit. Typical figures across the 3 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 65 to 79 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.
