This may be the problem; you need to let the sterns drift down wind; not swim/kick the bows to the wind.

If you are forward you are sinking the bows; trying to swim them round is going to be difficult/impossible; let the wind blow the higher-flowting sterns to drift away.

Problem is if there is a strong current from the same direction. The bows being pushed down dig into the current. Usually, it results in a 45% angle to the wind.

I recall watching you that night and from the stand it looked like you were doing all the right things.

I agree, the problem can be the issue of getting the bows in the right direction and then getting on the hull in time to right it. In 15kn of wind, should be no problem getting it back up even if you weigh 70lbs. I haven't had an issue recently... but I don't sail the boat very frequently.

in 15kt's you could damn near right the Titanic singlehanded.

(edit)- Its the days when you're screwing around on the low side in light air its tough to right a singlehanded F16. When its blowing its pretty easy. Add some waves its even easier.
