If there is bilge access close enough to the step, you may be able to view it. My Morgan only had a small access to the bilge, closer to the engine compartment. It could be used to inspect where the CB penant attached to the CB. I ended up replacing the cabin sole, and put in better access to the bilge. That reminds me. You or your surveyor should pay attention to the cabin sole. Mine was 3/4" ply laminated on both sides with glass w/ a teak and holly floor above that. Water wicked into the plywood and the from the edges and the glass held the water in, allowing the floor to become pretty spongy.
