Designing a yacht is to take many aspects into consideration. What you point at are two of them and you see a design conflict already there. I think all of the yachts in this thread has aft engine rooms, except the two LRC cruisers where the aft stateroom gives the owner a better privacy. On smaller round bilge yachts, it is a better option to have the engine room in the gravity center and the props on shafts not too far aft where they usually get airborne in heavy seas. You also have the stabilizers fitted in the engine room. With all aspects, including available hight in such hulls, the central engine room makes most sense.
With the crew, I agree somehow on sailing yachts or bigger motor yachts. Sailing a modern boat is definitely a slamming experience in the bow, even if you often make the long passages without guests and can move aft. And you canīt mean that the owner should be happier to sleep forward then?
In port you have the problem of where to be when on the yacht. Crew traditionally have the foredeck area with their accomodation below. The owner and guests prefer the aft deck and live below. By shifting these living areas you have created a new problem.
As you see, each yacht has itīs ideal solution and I have examples on all of these configurations in the designers forum. But my best advise to keep the owners happy is to give them these yellow things to put in the ears before going to sleep. It never fails...
