More things to consider. Fast startup.

Short picture to picture delay. Wide angle lens.
Fast lens. Try for at least 2.8 at the wide end of the zoom. My new Canon G15 has 1.8 to 2.8 over its 28-140 zoom range, better than some SLRs. When paddling, you *will* struggle with low light conditions, and many waterproofs seem designed only for sunny days.
The number of pixels is less important. In fact,fewer pixels can mean faster shot-to-shot. My 5 year old Canons have "only" 7 megapixels, but that's plenty for even 8 by 10 prints, and allows cropping for closeups. New waterproof cameras usually have at least 12 megapixels, and that's plenty! Take more only if they come with other desirable features.
