Jeanneau · Ron Holland · 1980
Updated
The Rush 31 is a 9.24 m heavy displacement racing yacht designed by Ron Holland and built by Jeanneau, first launched in 1980. It races in Class C. Across the measured fleet it goes better than its own numbers promise, ahead of 49% of the designs it races against. It is at its best in light air and struggles to hold that once it blows.
Goes better than its own measurements promise, and does it better than 49% of the boats it races against.
82nd of 159 in its class.
This design has been found in real race results — 36 starts across 24 events — not only in measurement files.

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 design is even-tempered. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is on the run in a working breeze, where it outruns what it looks like on paper. It holds that advantage on a broad reach as well, so the gain is not down to one leg of the course.
Where it pays
It falls short cracked off in a strong breeze, giving away time it never gets back. That is weight that has to be driven rather than released.
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 downwind.

Rigging
Rush 31 rig and sail dimensions
A Rush 31 carries 9.90 m of mainsail hoist on a 3.07 m boom, a forestay 11.60 m above the deck and a 3.67 m bowsprit. Typical figures across the 13 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 47 to 54 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.
