Recently I had the same problem as Kris H posted earlier
I weigh around 75kg wind was 15-18knt capsised on a jibe when hiking footstrap broke Boat was beam on to wind with current and waves in same direction as wind
I could swim the bows to 45 degrees but not straight into the wind as soon as I got to righting position the boat would swing back to beam on.
The mast head would not come clear.. But the boat came up easy once a young guy of a speedboat helped me pull on the righting line
Any ideas for next time.. I typically sail in currents around 3 knots
Open main and traveller sheet, open rotation and downhaul, swim to the bow, sit on it and hang your legs in the water. I mean the bow, not somewhear near the front beam, really the tip of the bow. If it will not turn, go in the water and grab the spi bridle (and maybe the righting line for safety), be patient. Your are the sea anchor to turn the boat. Once the wind is going under the sail, you have done the job. In really strong wind, if you right the boat, stand in front of the front beam. If not, the boat may start the bear away during righting, but with you on the wrong side... (don't ask why I know).
Cheers,
Klaus
