I've got an Old Towne 147 guide and used it primarily for duck hunting. As stated, great initial stability, easy paddling. I would not stand up in it but that's me. I've been using it for paddling with my young scouts (sons) and it's been great. I like the riggers shown above and would add them for bigger water with the boys. I've only had it tipped once, when a duck hunting partner with no canoe experience dumped us while I was stepping into the boat. Should be great for what you want.
