All of Farrier's designs are set up to take about 30 knots of wind to cause a capsize if you full sails up sheeted in and take the wind on the side.

The 31 is not an unstable boat by any means, IMO, so it depends on who is doing the talking and what the circumstances are. There are designs that are les powered up and therefore more "stable", and some that more posered up and less so. Some of the capsizes lumped into the 31 categorie are also very modified boats (Cheekee Monkee), or are racing versions of the F-9r, which are not Corsair F-31s.

There's also a certain multi design group that would like you to believe the 31 is bad that way so that action being taken against their boat would seem unjustified.

Also, the new 31-1D is an updated and hopped up version of the original boat that Corsair put together, it may be a little more high-strung, but nothing I would call unstable.

I had come across a Dragonfly forum not too long ago that were posting how all the Farrier and Corsair boats were high-strung and capsize prone and unsafe. All a matter of perspective...
