I am wondering if I could get some suggestions on a kayak. I want to use it primarily on the Fox river in calm areas and travel into the marsh areas to do some photography. I am fairly petite, so heaviness is an issue. I would like some room to move around and carry some equipment with me. Obviously, I don't want to use the kayak for its normal use of rolling and tricks. The more stable the better. Any help would be greatly appreciated!
