It’s not the standing which tips most canoes, it is the getting in the standing position. Yeah, you can get away with it when the water is wide, calm and shallow. But that doesn’t mean you should. Generally, if the tallest guy is in the front of the canoe (that was me back in the day), you could scout ahead just by kneeling up. Much safer for the rest of the people in your canoe, particularly with the true “v” hull in the painting.
Perhaps if you spent your summers in a canoe on streams, lakes and rivers, as I did, then you wouldn’t have your fears about tipping. Yes, v hulls are skitterish but they didn’t present any problems for us kids.
