Depends on the boat... I mean ship *nods to Tin* I've done a VERY brief ride on an LPD and a carrier... the racks were stacked 3 high on the carrier, 4 high on the LPD (gotta cram us jarheads into the accommodations as much as possible! *laugh*). It actually wasn't horrible... kinda like being in a close-in dorm setting, but I can see how it would get a bit wearing after a while. Carriers are small cities unto themselves, though. I can imagine that being on a DD or FG might be a bit less impersonal.
