In exploring a M/Y design, eliminating the main deck, saloon level walkway (side deck) has been suggested to bring the edge of the saloon the edge of the hull on one side. This would mean that fore/aft movement would only be possible on the other side at the main deck level, but the level above (saloon roof) would permit walking from fore to aft at the edge of the hull on that side for deploying buoys and so forth. The boat is a monohull 70ft+ and will dock stern to presumably. or dock on the side that has the walkway.
Which side would you choose and why?
