Good for you taking a bath when it wasn't necessary. I have pulled people without a clue from the water and on the worst of days- of course, because those are the conditions that result in capsize.
I don't know how you'd get a Getaway up solo but here is the good news for anybody practicing righting on any boat: the wind gods that blow you down try to make amends by helping to upright you too
In reality you probably aren't going over when there isn't any wind. You will one day or the other go over when there IS wind and waves. If you don't go over at some point, you ain't sailing hard enough.
So, with the downed-boat mast about 45 degrees INTO the wind (or perpendicular to it) the wings and trampoline and the boat itself are acting as sails being blown towards the righting direction. This is a good thing. To complicate matters on a calm day, the sail on the water tends to "seal" itself to the water. If the water is dead flat with no waves it suctions down self pretty darn good. Waves help break the suction and the wind also works it's way under the sail to help lift it.
So if you can, although it is not as much fun as swimming on a hot day, practice this move under "realistic" conditions with help nearby.
Oh yeah- your life jacket doesn't work if you don't wear it- please don't end up as a guest of Davey Jones.
