Me Too!
Craig, I'm scraping the bottom paint off of my 1972 23', on a bunk trailer, right now too! I was planning on using two jacks, one on each end of the stub keel to gently raise it, as I provided additional supports under the bow and stern. I need to get the centerboard unstuck while I'm at it, so I need some extra separation between the keel and the rollers. Otherwise, Jim's idea about lowering the bunks is a great one! Man, I hate all the sanding! Let us know how your project goes, and I'll do the same.
