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.
There is no obvious weak spot here. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is across the wind when it blows, where it does more than its size and sail area promise, and by a margin worth having.
Where it pays
It falls short on the beat in the light stuff, giving away time it never gets back.
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 beam reach.

How they are set up
The range each sail spans across the fleet.
Nearly all carry a folding propeller. Crew weight is declared around 650 kg.
Rigging
Ro 400 rig and sail dimensions
A Ro 400 carries 14.29 m of mainsail hoist on a 4.72 m boom, a forestay 15.06 m above the deck and a 4.63 m bowsprit. Typical figures across the 2 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 92 to 114 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.
