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 needs pressure to show what it can do. 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 once it pipes up, where it goes better than its measurements say it should, and by a margin worth having. It holds that advantage off the wind as well, so the gain is not down to one leg of the course.
Where it pays
It falls short upwind when it blows, giving away time it never gets back. That is a hull that wants to get up and go, and needs pressure to do it.
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 2.6 kn either way.
At 10 knots this design makes back more than its rating asks on the downwind.

How they are set up
The range each sail spans across the fleet.
Most run a fixed propeller. A bowsprit is standard across the fleet. Crew weight is declared around 570 kg.
Rigging
Henderson 30 rig and sail dimensions
A Henderson 30 carries 11.73 m of mainsail hoist on a 4.39 m boom, a forestay 11.31 m above the deck and a 5.41 m bowsprit. Typical figures across the 5 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 94 to 102 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.
