When we use a 3 person canoe we have the front person use a kayak paddle.  For us it works better than a regular paddle.  Fast and straight.

As far as fishing goes, I am trying to remember the configuration, but all 3 use Rod Sentry's   (You need to Login or Register.

I think the bow paddler and the stern paddler were on the same side, with the bow paddler straight out and the stearn paddler straight back.  The middle paddler is on the opposite side.

It's not to bad, no crossed lines to speak of.
