A pirogue (remember the "g" is silent) is as stable as a paddle board and larger ones compare to a wide kayak or canoe (actually more stable than a canoe).
Locals very often use them like a paddle board but will use a push pole rather than a paddle. That takes more balance than I possess. I've seen them fish, hunt and cast a cast net from them, and "Swamp People" have hunted gators from them (wouldn't recommend doing that). The wood construction of original models makes them perfect for duck hunts as the wood ages and becomes part of the camouflage.
