I get very seasick. I've been on boats and ships and IMO it depends on the size of the boat, the body of water and the size of the swells. On a ship in the Carribean I was not sick. However when the ship entered the ocean to sail to Jamaica, boy was I seasick. Apparently the deaper the body of water, the bigger the swells. I think it just depends on how seasick you get.
We went on a whale watching tour in Hawaii several years ago and they said it was a large boat. That was the longest and worst 3 hours of my life. I spent most of it hanging over the boat. Ugh I hate that feeling. :zombie:
However, I love the idea of going on a cruise with fellow knitters.
