This is a good set of posts. I'm prone to seasickness myself, and have used Bonine, Ginger Altoids, and Ginger Licorice (available at Cost Plus World Market if anyone is interested - warning, it's STRONG!). All with mixed results...the Bonine makes me a little drowsy (but not much) and tastes funny to me. Dramamine puts me to sleep. Ginger messes up the stomach a little...
Someone mentioned the patch earlier, and I've seen people with it but haven't tried it myself..I think I will next time. If the only drawback is dry mouth and you compensate by drinking, you're just helping out the "hydration requirement" of SCUBA in general, so it kinda sounds like a "win-win" to me.
One other thought for folks is there is a liveaboard dive boat called the Nekton (there are actually two) designed using the NAVY's SWATH concept (submerged pontoons). The theory is that by keeping the "base" of the boat beneath the majority of the surf, the ride is significantly more stable than any typical hull. The claim is that while the boat is only about 80 feet long, it rides like a boat 10 times its size. I personally have taken a Nekton week-long trip and it does indeed have a good ride, and excellent crew. I still needed *something* to get me past the seasickness, but I can only imagine if I was on a less stable boat what it would have been like. I am booking on the Solmar V which is a more traditional liveaboard, hence my interest in the patch. Just for fun, here's a render of the Nekton I did:
On a final note, one of the interesting things about being on a liveaboard for a week is that when you step off the boat onto the floating dock, you can really feel the dock moving, so you walk on to the land...and it doesn't stop moving, so you look back at the dock only to realize it's anchored firmly to the pilings holding it up...you *still* feel the land moving....it's a "reverse acclimation" that you're experiencing (or if you prefer, you have gotten your "sea legs"). I've actually heard rumors of people getting "land sick" in this situation...does anyone know if there is any truth to these rumors?
