How long are the beds on the average survey vessel? How difficult would being 6'5" make it on a survey vessel

I'm looking into a job on a survey vessel and the only thing I'm worried about is being so uncomfortable that I can't enjoy my job. There is no specific vessel that I would be working on, so I'm just looking for general information. Also if anyone has anything they would like to share concerning living on an oceanic survey or research vessel I'd love to hear it.
