Easy hatch

hatch1
8″ boat access hatch from ebay and MEC 35 litre dry bag
hatch3
cut hole in deck and dry bag and make a plywood ring which is put inside the dry bag before closing it. I used stainless steel bolts and exterior paintable caulking.
hatch5
It didn’t slacken the skin very much but next time I might put in the hatch before painting so I can shrink the skin around it.
