Normal
As Paul Harvey might say, from the for what it's worth department, some folks suffer from motion sickness in an automobile, while others are practically oblivious to the motion of a small vessel in 10 foot seas. At other times, at least in my experience, something else is at work when an attack of motion sickness comes on. I have been deep sea fishing many times in pretty rough seas and had never experienced motion sickness until one Saturday a few years back. We left the dock at 7 AM in a 36 foot vessel in relatively calm gulf waters. By the time we got out to the first reaf, I was fighting to keep from heaving my guts out. I remained nauseous until we returned to the dock. It has never happened since; go figure. I do think that Grand class ships seem to have a lot of motion, especially pitch. This is somewhat strange given the size of the ship. I recall being in the lap pool one morning and the waves in the pool were enormous due to the ship pitching back and forth. I thought it to be much fun!
