I think the canoe is great for accessing shallow wetlands. The draft is only about 6-12 inches. Great to paddle in, get out, and tuck it in the reads. They're pretty darn unstable in the heat of the moment. I used to have one, and could get my 85 pound retriever in and out without a problem. He'd put his front paws on the gunwhale, and I haul him in by the scruff. However, when we jumped a bird, all bets were off. I'd hate to go in frigid water with chest waders, not to mention all my gear dropping out of site.
In the end, I think there's a lot of romance to it, but practically speaking, it's more transport than hunting patform.
