Probably not.  Maybe one out of 300 do for maybe an hour.  We are island hopping on big catamarans with two hulls.  They are very stable and don't roll.  We also cruise in flat protected waters. 85-90% of our first time boaters return to BBS. They would not do that if they got sea sick each time they returned. This is island hopping done right.
