Managed to get the deck built and glued onto the first float with all the HD foam inserts in the right place.
HD foam ready to put into the deck and float ready to have the deck glued on
Then the deck glued on
Work also continues on the second float with the bulkhead flanges, compression strut and chain plate in place. So now I will continue to fit the deck to the second float and shape them both before laminating the outside skins.
