I have had my 216 on mooring for a month now, and changed the tie-up scheme a few times. Still not secure with it though, as when the dealer installed the facotry spinnaker kit, they removed the starboard deck cleat leaving me with only the single one to tie up with. The dealer scoffs at my concern over mooring to the bow eye stating "you could dangle the boat from a fork lift using only that eye."This is not to mention the fact that the thing yaws around at the mooring more than any other boat when there is any wind despite my effort to reduce windage. Instinctually somehting tells me I could reduce it if I had the other deck cleat. (too late for that).Bottom line as to the cleat question, are these bolted through onto a metal plate or just scewed into the plastic/foam sandwich?
