Thanks so much for all of your help! I went out and dumped it to try some of these. What worked for me was to cleat the jib sheet - throw the rope over the other side...then I pulled on the rope and walked up the bottom (side now) of the boat til it started tipping back up!
To get back in, I used the advice to have a rope with loops tied in it...and just put it over the tiller.
Thanks so much!

Maybe this is a stupid newbie question, but why not lower the main before righting the boat?
