Under bunk cargo hatches ...

Today I put my faith in the hands of the gods of fiberglass and cut into the side of my egg to install two cargo hatches. (see picts)

Things went well, and now I have two giant holes under my bunk. The hatches test fit OK. I'll do the final install after my paint job.

I purchased my hatches from Boat Parts and Marine Supplies - Great Lakes Skipper . In retrospect, I'd think twice about using boat hatches, as they are not designed with fasteners that pull the hatch edge tightly against the fiberglass; the hatch has screws which are perpendicular to the edge (which would work well for a thick outer wall or deck). I'll have to install some wood behind the 'glass for the screws to work.

Looks great. I think it's a good idea to add the wood anyway. Remember my comment about ridigity

Ditto Donna's comment. A 3/4 plywood frame will restore most of the strength in the wall, and if you have to screw through the fiberglass, it gives you something to bite into. Although when I installed a similar hatch, I used SS machine screws, washers, and nylock nuts.

You're gonna love having access to the storage.
