Oceanis 311
Beneteau · Jean-Marie Finot · 1988
Updated
The Oceanis 311 is a 9.54 m displacement racing yacht designed by Jean-Marie Finot and built by Beneteau, first launched in 1988. It races in Class C. Across the measured fleet it goes better than its own numbers promise, ahead of 13% of the designs it races against. It comes alive as the breeze builds, and gives time away in the light.
Goes better than its own measurements promise, and does it better than 13% of the boats it races against.
139th of 159 in its class.
This design has been found in real race results — 10 starts across 5 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.
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 on a broad reach in a strong breeze, where it does more than its size and sail area promise, and by a margin worth having. It holds that advantage across the wind as well, so the gain is not down to one leg of the course.
Where it pays
It falls short to windward in light air, 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 0.6 kn either way.
At 10 knots this design makes back more than its rating asks on the beam reach.

Rigging
Oceanis 311 rig and sail dimensions
A Oceanis 311 carries 11.07 m of mainsail hoist on a 3.94 m boom, a forestay 12.43 m above the deck and a 3.83 m bowsprit. Typical figures across the 12 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 54 to 65 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.
