That sounds like a tippy proposition to me as well but it all depends on where -and how- you're using the canoe.
In windy, tidal waters deeper that 4-6 feet?... no way.
In back waters or flooded timber? sure!
With a young, active dog and decoys? Not me!
To use as transportation and not as a blind? why not!
Early season/mild weather?... Sounds like fun!
Late season/freezing weather... Tip it over and you could be done...
Bottom line: Like any type of boating/hunting situation you have to play the conditions. If you have to seriously pause and ask the question:
"Is this a good and safe idea"... The answer is always "NO!"
Again, if you have to ask the question... there is no question.
