My Meyers Sportspal S-15 has oar locks as an option and I bought them just to have them. You never know.
It is a wide canoe, 38", and so it would negate "part" of the issue PC brought up regarding the ergonomics of good rowing.
Better? I use a double bladed 280cm paddle (about 9' 3") and I really like it. One of the issues with a wide bodied canoe is it is the very least efficient paddler out there of all canoes; but, the good thing is it is super stable and I stand in it effortlessly, even in wind and rough water. But, you have to sacrifice one to get the other and I like to stand to fish so I burn some extra calories paddling, that is for sure.
Oh! If you "single" paddle a wide bodied canoe, you quickly lose forward momentum while moving the paddle back and forth side to side. Inertia is your enemy. But, with a double bladed long paddle, it seems to keep things moving along better. as each stroke is closer to the next in time. Hope this helps. Brad
