Is this going to be a problem? Last Spring I removed the rust and refinished my cast iron keel. I got to everything except the bottom of the bulb where it rests on the trailer. I was planning when I haul her out to soon to block up the front and rear of the keel so next spring I could get to the places I missed. Then lift the boat again and move the blocks to the center to get at the final areas of the bottom. The keel has a flat contact spot along most of the bulb. I would also have the pads raised the height of the blocks so everything should be the same except a little taller. I only have to move the boat from the crane to my yard space almost within sight of each other. Would this be okay on a 11K displacement boat? The weight will be reduced to the contact area of the blocks. I can't see any other way to do it. I can't tie up the crane for the entire process.
