All I'm saying is that instead of having three bunks under the hatch, just have one ladder bolted to the wall, with emergency lighting. No change to the hatch.
Do you believe that bunks are a real problem? Almost every small boat in the harbor has the forward deck hatch next to or above bunks. Is it any harder to climb on a bunk than a vertical ladder? Of course the answer is "sometimes yes and sometimes no". This is an important discussion, if for no other reason than to make people think about it before selecting a boat.
It would be interesting to see how people's selection decisions would change if everyone had to perform an emergency evacuation drill through all points of egress before casting off. I have seen some large divers that couldn't get through typical emergency hatches. Same with some elderly and injured divers. Better lighting might be a good thing but not if it is just window dressing. A full system approach is required. Again, just discussing and NOT arguing.
