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 one is at home going to windward. Windward-leeward courses give it more of what it is good at than a coastal race does.
Where it gains
Its best ground is on the beat in a working breeze, where it does more than its size and sail area promise, and by a margin worth having.
Where it pays
It falls short downwind 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.
Full width is 0.4 kn either way.
At 10 knots this design makes back more than its rating asks on the upwind.

How they are set up
The range each sail spans across the fleet.
Nearly all carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 850 kg.
Rigging
Sun Fast 43 rig and sail dimensions
A Sun Fast 43 carries 16.01 m of mainsail hoist on a 5.54 m boom, a forestay 17.75 m above the deck and a 5.11 m bowsprit. Typical figures across the 3 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 108 to 140 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.
