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.

Speed in knots at 20 knots of true wind. Green marks the angles that pay: the closest useful beat and the deepest run worth sailing.

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 running deep when it blows, where it does more than its size and sail area promise, and by a margin worth having. It holds that advantage on a reach as well, so the gain is not down to one leg of the course.

Where it pays

There is no condition where it falls away badly, which is worth something over a season of mixed weather.

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.

A Sydney 47 carries 18.23 m of mainsail hoist on a 6.41 m boom, a forestay 19.03 m above the deck and a 6.35 m bowsprit. Typical figures across the 2 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 158 to 170 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.
