No, I used 4000uv 3m marine sealant between the diamond nonskid deck and the bottom of the base plate. It’s thru bolted underneath. Half my plate is bolted through the section of the deck that has the metal piece glassed in, the other half of the plate is bolted aft of the plate. Then there is another pretty plate as seen in photo that goes over top and covers screws then the stanchion attaches to the pretty plate. Release does have a plate you can recess into the deck. You would have to route out the deck in a 4” circle I believe then mount the plate.
