I have a 1988 16’ Fisherman, and the cockpit is not enclosed. As we know, many C-Dorys were built with a “floating” helm bulkhead enclosing the cuddy cabin, meaning the sides are not sealed to the hull. Instead, there is a small gap around the entire perimeter. We have wasps in my area and I know they will use this gap to nest in the cuddy cabin area of my boat. Has anyone ever sealed this perimeter gap with expanding foam or something else?
