I think today the hot setup is the Pentax Optio 33WR. You get a pretty
upscale digital camera good for temporary immersion to a meter of water.
Sounds about right for boating.

You are probably correct. This camera was introduced last October, so
there aren't many reviews of it yet. Steves-digicams.com likes it.
Neither Dpreview.com nor Imaging-resources.com has reviewed it yet.
The primary competitors are the Stylus/Mju 300 and 400 from Olympus,
and according to Dpreview.com both those produced mediocre results.
Biggest problems with the 33WR are barrel distortion at "wide" angle
(37mm SLR equivalent) and pincushion distortion at telephoto (104mm).
