I am at the point where I will be making hatch cut-outs on my Auk 17. I used the hatch offsets from Nicks book. When I laid the pattern for the forward hatch on the deck, it looks proportional to the deck. When I put the pattern for the aft hatch in place, it looks quite large, and looks like it would weaken the deck a lot. I know I can make it smaller, but if all I am seeing is a bit of an illusion because of being in then shop, and it really isn't too big, I may just go with it. I'm not sure that I will need two, so I'm looking for an opinion from experience. Day trips and weekend camping is likely all it will see.
