Is this something that eventually goes away after repeated boating?
What can be done about it?

Yes and no. A good deal depends on your tendency towards motion
sickness. If you are not normally prone to motion sickness, once you
begin to sense the motions experienced on a boat you may encounter the
problem fewer times or not at all.
If, however, you ARE prone to motion sickness, the best you can hope for
is that one of the various remedies will work for you and that you can
either deal with it and get over it or pick your times when you go boating.
I have been prone to all forms of motion sickness all my life and have
lived to deal with it (hell of a profession to chose for someone who
gets seasick) and notice that as I've gotten older and number, I am far
less prone than I was in my youth.
