deck on the port hull removed.....

now we can see what's been going on and why we have such a mess on our hands
The foams have collapsed at some stage and rather than removing the deck properly they've opted to run a jigsaw down the inside edge of the gunwhales, resin up the broken foam, add 2 strips of ply to the gunwhales to bulk them out and then resin back in the original deck ply.
