I'm primarily an angler, and my little boat just a means of getting to where the fish are. Seasickness was the bane of my sport, but finally Dramamine fixes all that, taken well before setting out.

Also, it isn't motoring about that sickens me, because I'm looking about. It is doing things in the boat, like baiting up, watching the rod top, etc. Both points pointed out earlier. If I fish with a jig, which means I stand up and work it by feel, I get no problem, because I'm looking about.

Dramamine is far the cheapest drug available here, only cents a dose. Some other 'cures' I suspect, because I once took a proprietary brand before setting out, but the weather worsened, so I didn't go, and I got nauseous at home!

Hope you can translate this from motorboating to sailing.
