Hi there,

My vote would be for either an original U-boat style or a bladder-pontoon, altered U-boat style float tube. I've got a Woodstream Stealthrider (too expensive) u-boat. The next tube I want would be the pontoon style Outcast (Super) Fat Cat. It's very reasonably priced although the valve hassle is bothersome. Lot's of pro's and con's and quite a number of tube sites' message boards you should surf. Use google.com and throw a few keywords in and see what happens.

Do those little blue fishies nip at your heels? ha ha

Good Luck!
