Went deep sea fisihing in FLA about three years ago and had a rough time. Captain said there were three to four foot swells. He told us that he wouldn't recommend going if we had never been before, but if we wanted to go he would take us. We all thought three to four feet wouldn't be bad and decided to go. Boy was that a mistake. All but two of us got sea sick. It was a rough day to say the least. Didn't catch a ton of fish and being sick made the experience pretty bad. Not saying I won't go again but the would have to be a lot calmer seas for me to go again.
