not to knock a kayak or canoe but I think I have the perfect medium. This is what I have and I love it. I can fish all day long in this and I never worry about tipping over or running out of battery. I've had this for 6yrs and when this one wears out, I'll get another. Here is the link to the one I have. It's the Caiman 10.
