The good thing about the Clearwater is there are a lot of ramps so you don't need a really shallow running boat to fish it. I wouldn't fish it in any boat bigger then 16' and a prop unless you really know the river.

Your better off looking for a 16' Alumaweld or similar. A 66" bottom provides more room and is better setup as an open boat and fishing. Having removable seat boxes is a big bonus and allows you to remove a seatbox and add a cooler to balance the boat out.
