The same power to weight ratio numbers apply to wave power.
Sailing our yacht at night with only the stars and compass to entertain one, used to wonder about using wave power to generate electricity, and as an even more direct use, to operate the pumps for desalination of sea water. In those day I could do the calcs in my head, not so much any more.
A seven ton yacht, up and down a wave X ft high every Y seconds.
If is pretty tough to beat batteries for economy as battery prices fall each year.
