Hi ,
Personally, I can't say because I don't go boating. It aggravates my dizziness symptoms, which are part of my migraine attacks. It wouldn't surprise me if boating could be a migraine trigger for some people. Do you keep a migraine diary? That would be a good way to track exactly when you have migraine attacks and whether boating affects them.
Hopefully, some other people will join in with their experiences with boating. In the meantime, take care.
