I am a new prospective cruiser. As I learn more about how cruising works, one thing I am concerned about is the comfort of any passengers I might have on board. For the type of trips I would like to do there would be significant time spent in open ocean 20 miles offshore or so. Even on a calm day, I imagine that 5-foot swells would be typical. Therefore, the boat will be moving up and down constantly. Is it viable for passengers to be reading or working on the computer while the boat is riding up and down on swells like that? I would think they might just go nuts after a 4 hour roller coaster ride. How do passengers cope with this problem?
