Chock up another reason mine ain't no blue water boat...There are 15 ports and 5 hatches...I would need a trailer to haul all that plywood..
From what I understand, a bluewater cruiser should carry precut plywood blanks for every hatch and port on the boat and have a means of attaching them, especially with newer boats. The ports on my boat are old school bronze ovals with 1/4" thick glass. Anything strong enough to break them is likely going to tear the entire house off. The old wood hatches are a different story.
