A number of heavy wood blocks from the boat yard hold the deck in place while the bonding compound cures. A little bonding compound was left over so I filled a portion of the hull extension to hull joint in preparation for fairing the joint and ultimately new gelcoat.
Deck in place and chain plate is slipped into it's slot to ensure a perfect fit. The chain plate will be removed while the deck joint is perfected, non-skid is gelcoated on and every thing is polished up. At the end the chain plate will be bolted up tight and then some sealant will fill the tiny gap around it's penetration through the new deck.
This picture was take on the starboard side to show the thickness of the build up for the chain plate base. The build up is of Epoxy and 17 or 18 oz biaxial cloth backed with 3/4 oz mat.
