Oceanis 381
Beneteau · Berret/Racoupeau · 1998
Updated
The Oceanis 381 is a 11.37 m heavy displacement racing yacht designed by Berret/Racoupeau and built by Beneteau, first launched in 1998. It races in Class C. Across the measured fleet it goes better than its own numbers promise, ahead of 40% 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 40% of the boats it races against.
96th of 159 in its class.
Updated — First Race Edge for this design. Enough boats of this design have now been measured to rank it.
This design has been found in real race results — 70 starts across 30 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.
It does most things without giving much away. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is on a reach in moderate air, where it outruns what it looks like on paper, and by a margin worth having.
Where it pays
It falls short off the wind 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 beam reach.

Rigging
Oceanis 381 rig and sail dimensions
A Oceanis 381 carries 11.74 m of mainsail hoist on a 4.60 m boom, a forestay 13.70 m above the deck and a 4.65 m bowsprit. Typical figures across the 8 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 65 to 91 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.
