This one’s simple. It’s the one you don’t fall out of, injuring yourself, or worse. Big boat. Small boat. Canoe. Kayak. It really doesn’t matter; all must be operated with a good dose of common sense. For fishing purposes, a shorter (14-foot) and wider (35-40-inch) canoe with taller sides is going to provide the most stable platform. But again, safety depends on you, the skipper, and the use of common sense. And always…always…always wear your PFD.
