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.
It is an upwind boat first. Windward-leeward courses give it more of what it is good at than a coastal race does.
Where it gains
Its best ground is across the wind when the breeze is soft, where it outruns what it looks like on paper, and by a margin worth having. It holds that advantage upwind 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.
Full width is 0.4 kn either way.
At 10 knots this design makes back more than its rating asks on the upwind.

Andrews 56 rig and sail dimensions

Sails
The spinnaker spreads widest of all — 162 to 211 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.
