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 is a boat that wants breeze. Give it a fresh day and long legs and it delivers more than it promised; in a drifter it is working uphill.

Where it gains

Its best ground is downwind in a strong breeze, where it goes better than its measurements say it should, and by a margin worth having. It holds that advantage cracked off 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.

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

Santa Cruz 50 rig and sail dimensions

A Santa Cruz 50 carries 16.80 m of mainsail hoist on a 5.65 m boom, a forestay 18.70 m above the deck and a 7.39 m bowsprit. Typical figures across the 4 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 182 to 220 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.
