I think that your warship accomodation was probably a cut above the minimum fare cabins on the old, now EXTREMELY old, budget liners.
Was asked, recently, if I would travel in one of the 9'X10' First Class insides aboard Normandie just for the experience of being aboard her. The answer was a hearty "No." I would not, in fact, even cross in Deauville or Trouville if time travel became an option. Experiencing the real life Normandie could not possibly measure up to her posthumous reputation (same is true of the Titanic) and actually being there amid the drunken, loud, whiny passengers, and dying winter garden birds, documented in her preserved Night Watch books would have to be a major let down.
I think the only way we will see a return to the long bows of old is if a way of making the space within them cost effective can be devised. Michael, I know you are aware of what a bow cabin can be like in a rough sea but, Jamie, one of the reasons the long tapered bow is no longer used is that the area within it will be MORE space filled with cabins no one wants to rent (if they can avoid it) because of the exaggerated sense of motion which, even in a calm sea, is always present in the forward extremities. Was recently in the furthest cabin forward on a voyage, and for only the second time aboard ship, in a lifetime, started to feel quite queasy at one point. Can't imagine what that room would have done to someone aboard a ship for the first time! When people NEEDED to cross by ship, and had no choice in the matter, such cabins ended up the realm of the Second and Third classes- now, in an era where people are only aboard ship by choice, there is little sense in creating cabins space which will only foster ill will among the clients.
In a similar vein, the rounded cruiser or counter sterns although attractive, create dozens of oddly shaped cabins which are (nearly) impossible to prefabricate (inexpensively) and which few people, if given the choice, would want to occupy. Which is why the odd shaped stern cabins on the few remaining older liners tend to fall into the budget end of the price spectrum.
