I solo a Discovery 158 which i installed webbed seats. I experimented to find the most stability. If I sit on the front seat and paddle the canoe backwards (but forward), stability is very bad. If i lean to one side, i will tip over very easy. If i kneel on the floor next to the front seat ( and paddle the canoe backward, but forward of course) stability is very good, and i have a lot of control. If i sit in the rear seat with 60 pounds under the front seat, stability is excellent. If i kneel next to the rear seat, with 60 pounds under the front seat, i have the best stability. With this, i do lose some maneuverability.
