cutting the escape hatch in the hull

I had taken the afternoon free from work to cut the escape hatch in the hull. I first trimmed the edge a little shorter. I then did some trial fitting, when the panel did fit I draw the lines on the hull to cut the hole in the hull. After some sanding the edges with the powerfile the panel did fit nicely. I then glued the panel with some putty in place. I then routed the foam from the holding tank top panel away so that the hatch is almost flat with the top and put some putty on the place where later the bolt will come.
