Never had one on a canoe. My son and I fished several times this summer in a fully loaded 12' tinny with only a 30 pound thrust Minn Kota. It got us everywhere we wanted to go including into some decent breezes and we were near capacity for the boat (both of us are vertically challenged). So my uninformed canoe opinion is that a c-30 and at least a class 27 battery will make you happy.
