Deck Organizers I have an '85 Hunter 31 and I need to replace the original deck organizers.I bought Garhauer replacements, but the mounting holes don't line up, so I have to drill new holes. I assume there is a backing plate of some sort under the deck that these bolts are threaded into. My question is how big is the plate, i.e. how far can I offset the new holes and be sure that I'm in the backing plate?
