20 knot breeze solo is crazy... And LOTS of fun...
My experience in conditions with that much of a breeze VERY often leave me doing a "Y" turn by backwinding the main and pushing the rudders over.. It is hard to imagine there would be enough current where that wouldn't work... tacking is VERY difficult solo... The extra hands and mass of the crew really help in those conditions...
What I have been doing as I get better... With that much air the jib is going to be traveled out at least a little bit.... Unless you weigh 400lbs you are going to be ridiculously overpowered in those conditions.. So travel it and and main out just a bit to make sure you carry enough speed... As you begin to tack travel and sheet in on the main tightly using it to help you round up without to much rudder.. Keep adding rudder, and as you come in from the wire, and are just off head to wind, let the main off... As you go under the boom push up with your shoulder running out a good bit of main sheet, then cleat it off. You want to do this to make certain the main doesn't round you up or cause any more drag than needed while turning through the wind... At that point keep a close eye on the jib and move forward on the boat... Solo sitting on the rear corner casting can certainly cause you to wheelie... You have to be VERY careful to be very quick but smooth through all of this... in that much air you are already going to have the chop and waves slowing you down... So be smooth but fast. Then pay careful attention to the jib... You need to be ready to sheet it in quickly on the next tack but slow to break it... The trick when solo is not TOO slow though... Backwinding the jib will help the boat come around... and as long as there is air in the jib you can generally get it to turn... But the goal here is still to be moving forward... Once you break it be VERY quick to sheet it in... Just not all the way... Leave it fairly full until the boat begins to accelerate... and then trim it in...
This is what works most of the time for me... I certainly have not perfected it..
Having the jib battons pop over in heavy air has never been a concern or problem for me... If you meant to say "2 knots of breeze" Smooth is the key...
This video should have a couple demonstrations of the "y" turn in it... But it also contains many lessons on what NOT to do...
So you will just have to make that call for yourself..

This after a day of having plenty of trying to tack properly, and resorting directly to the "y" turn.... The battens hanging up ain't a problem.... Or even a concern.
