We have spent some time thinking about what to do if capsized or dismasted. We sail several distance races on the norwegian western coast each year, and if dismasted in a westerly wind we could only hope for hitting Iceland.. I think (hope) most catsailors have spent some time thinking about what to do, and rehearsed righting procedures.

We carry the standard righting line, which we have found to be sufficient for righting our boat (a Tornado). In addition, when we go out of our fjord and into the ocean we also carry orange smoke-markers, flares and some parachute-rockets. We also carry a set of paddles, but have found them to be ineffective if the conditions warrant a dismasting (at least for paddling into the wind, trust me!).

In addition to this gear, we would like a signal-mirror and a VHF. I think an Epirb is overkill, but I can see some situations where it would be a real lifesaver. We dont carry an VHF becouse the unit is quite expensive and so is the mandatory course (we have a good tradition for keeping safety equipment like airbags very expensive here).
In addition, we dress in drysuits. If it's cold, we use wool beneath..

Now, righting practice is something _everybody_ should do! If you dont have a powerboat to assist you, you can do it in very shallow water where a partner can hold the mast for you (do it on a quiet day, so the boat dont drift into rocks or something). Find a method that works for you, before going out again!
To capsize, just go out trapezeing and kick off with our legs (ready rudders, boards, sheet etc. before you jump off).

Knowing how to right your boat is very important for your and your crews safety..
