Gifts for a ocean lover

If I can't go to the coast and frolic on the beach in this frigged, cold winter weather then I can shop. Let's see, what would an ocean loving person want? Something interesting perhaps persnonalized gifts or a travel DVD, underwater travel of course. I would stay away from anything that was made from sea life. Don't buy preserved seahorses or something made from a sea turtle shell. Think before you buy that gift.
