Is it possible to troll in a canoe with one person padleling and one person fishing. Would you have enough speed to keep and action as in a motor boat trolling?

As wierd as it sounds you might try trolling some sort of plastics. I don't think you'd have the speed to keep a crank going right. You never know though. I've had a fish hit a topwater that was sitting out behind our boat while we were cruising with the TM.

Drag fishing might be easier than trolling.  That way the paddler wouldn't get worked plumb to death.
