I have been studying your excellent tips on righting an inverted boat.
I have had quite a bit of trouble with this recently (or fairly recently, ever weekend when I have been free to sail recently has been cancelled due to strong wind!), every time I go over, which is often, the boat seems to invert.
I actually use my righting line which comes from the mast rather than the halyard, ignoring the front beam one unless only capsized at 90 degrees, but have found that even balanced right out by the rudders and bouncing until exhausted nothing happens. The only way I have found around this is to take the righting line and climb out to the bow of the opposite hull and pass the line in front of the bridle wire so it is pulling right from the front of the opposite hull. I then go right back near the rudder opposite and lean out, eventually up she comes.
This is probably made harder in my case as a combination of being fairly light and short means much less leverage than our more comfortably built giants. In fact this is going to get harder as having had a series of injuries and problems over the last couple of years means my weight had ballooned to 10 stone and I am now well on the way to getting back to my running racing weight of 8 stone which means even less to throw about!
