You might also consider a couple of 8GB USB flash drives as backup.
Flash memory may better accomodate the shock and vibration of
a boat under way. When not in use, you can remove them and store
them in a plastic bag with some dessicant.

I lforgot about a memory stick in a shirt pocket I left out for
washing.
My wife recovered the memory stick in three pieces: two covers
and a little card and chip. I stuck them back together. It worked.

You could be right about USB flash robustness!
