My son and I are building an LT17-- our first boat. We're about ready to attach the cockpit coaming spacers to the deck, however when dry-fitting the first one I noticed that the forward edge of the spacer is about 3/4 inch aft of the deck beam. The manual says to drive a couple of ring nails into the deck beam to anchor the spacer. That would be a clean miss; I can glue a nailing block to the deck beam, or even add an additional beam, but this seems like overkill (not to mention cobby). Do the coaming spacers have to be nailed into the deck beam for support-- or is attaching them to the deck with thickened epoxy strong enough?
