Lots of factors are at play here, and people do certainly get sea sick. First thing’s first, if you have a history of this make sure and let us know so we can try and accommodate you as best as possible.
It’s most likely you should avoid offshore trips or trolling, but don’t rule it out on a good day.
Taking medicine the night before being on the water seems to help. We can’t tell you what to use but lots of folks seem to like Bonine or Dramamine, both of which are available at Walgreens or other stores in town.
If you get sick or we have to come back to shore, we unfortunately can’t give a refund, as we have already reserved the whole day, so make sure before you book a trip.
