I'll add my opinion to all the rest.

Seasickness is 50% physical and 50% in the mind. It is triggered by
confusion between the signals from the eyes and ears(balance).

The times I have been seasick, it was when I didn't get enough rest before
getting underway. The previous day were spent running hither and yon for the
last minute provisioning, rechecking the boat, and of course the bon voyage
party. I know this varies from the original post about the cruise ship, but
getting a lot of rest and a good night's sleep before going aboard will help
as they will be well rested. I had a friend who would leave the dock and go
to first anchorage close by, out of sight of the marina, drop the hook and
go to bed. He would get up at first light and then start his voyage.
