Well, I own one of the newest boats here. And we are planning to
buy a very recent boat, such as a Beneteau 50 something less than 5
years old

Crap, he hasen't even got the present one and he's already posting
about the next one. Personally I think when you move into the 50 foot
range you should be looking at something better than a Beneteau. I
guess they have 7 foot bunks and a great swim platform.
