Bow pulpit work on the boat

This is a picture of the anchor locker from the outside.  I believe I need to add two access holes, one one each side of the interior near the bow pulpit stanchions in order to get access to the nuts to be able to remove the pulpit.

This is a picture of the same area, only from the inside of the cabin.  I thought maybe this would be a good way to go instead of from the outside, but I'm not sure.

Either way, I am planning on installing access ports similar to the one shown in the top picture once I have made the repairs by replacing the rusty nuts and bolts and fixing leaking fiberglass.
