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.

Offshore & coastal

Level across both. Plenty of designs fall away once the course gets long — a light hull that thrives round the cans can struggle through a night at sea. This one does not.

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 a reach in a working breeze, 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 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.

Rigging

A Dehler 39 (Judel/Vrolijk) carries 14.92 m of mainsail hoist on a 5.50 m boom, a forestay 15.73 m above the deck and a 5.05 m bowsprit. Typical figures across the 24 boats measured under the current VPP, with the range each one spans.
