Does anyone have any experience with this camera for boating purposes?
I'm especially curious about the quality of whitewater action pictures
in typical boating (i.e. less than optimal) lighting conditions.

Sorry no, several of my friends own the Pentax Optio WPi and are
generally happy with it, although they all say it's not one of the
best digicams, although it is waterproof.

Other friends have a regular digicam inside a waterproof case.
This might produce better results, especially when you remove camera
from case and use it in landlubber mode. But cases are costly.

I was hoping to find some relevant info at Bill Tuthill's old
comparison site (http://creekin.net/cameras.htm ), but I found that the
domain was taken over by some company.

Yes, I sold that domain name and moved content to cacreeks.com
so try http://cacreeks.com/cameras.htm instead.

The Pentax WPi and Olympus 730 SW look similar except the Olympus
has more megapixels.
