A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Better the longer it gets. Boats that settle into a groove and hold it gain ground once the course stops turning.

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. On a windy coastal course it is in its element; on a light-air windward-leeward it has to be sailed well to hold on.
Where it gains
Its best ground is on a broad reach when it blows, where it outruns what it looks like on paper, 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
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 1.4 kn either way.
At 10 knots this design makes back more than its rating asks on the downwind.

Roughly half carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 600 kg.
Rigging
Mount Gay 30 rig and sail dimensions
A Mount Gay 30 carries 12.57 m of mainsail hoist on a 4.60 m boom, a forestay 11.70 m above the deck and a 4.51 m bowsprit. Typical figures across the 7 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 46 to 110 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.
