Moving Jack Stands

After pain, the stands need to be moved so I can paint the spots where they hold the boat. It's a bit of a scary job. Little Bear weighs in the region of 20K lbs. That's 10 ton. If I don't do the stands right & she comes down... She'd be difficult to put back up. That is if she didn't squish me first. Trying to put the boat back up post-squish would be problematic. For me at least.
