I duck hunted a fair amount from a canoe over the years. My opinion is that is should be used for transportation only. I've known of number of times that they've been tipped. Losing equipment, getting soaked in cold, cold water. Slow going back. Small waters they're O.K.
12' Jon boats are a better option, although I recall a number of incidents when they to have been overloaded with hunters, dogs decoys,etc. and then trying to cross rough, big water.
