A while back I posted about moving my mainsheet blocks (see pic below). I mainly moved them because in light wind, the blocks were banging into the gel coat, and would eventually damage it. The new placement has worked out perfectly. There does not appear to be any undue stress on posts for the gallows. Nice and solid!
