Unless you have a 30lb dog snoring on your lap:-xNice boat. I know what you mean about falling in love with being intghe outdoors with a kayak. Very pieceful and claming, but can also be very exhilarating depending on your skill and confidence level and the water/weather quality.
I use a SeaLife Reefmaster, which I also take diving (depth rating of 130 feet), but they sell the same camera, as the ECOshot (depth rating of 75 feet)=> http://www.sealife-cameras.com/cameras/ecoshot.html. Should be able to find it for about $200. YouTube => http://www.youtube.com/watch?v=1YuBWjOsjIgWhat are you using to take pictures with?
