Severe motion sickness and going on a cruise.?

My husband and I are going on our first cruise soon. My husband gets severe motion sickness in the car unless he is driving and he got really sick on a whale watching trip, was "feeding the fish" the entire time....and he took Dramamine before we got on the boat. I have read about the patch, but have heard that people get really sick after they take it off? Anyone have any successful suggestions without the awful side effects?
