I had the same problem on my viking tempo fisherman. I mounted 2 rod holders each side of of the yak halfway down my shin. I have to reach for them but atleast they dont get in the way of the stroke. (in saying that I troll at a slow speed and don't need big strokes, When Im moving locations I still mount them behind my seat.)
Just buy 2 rod holders and some double sided tape. Take the yak down to the water and work out where they dont get in the way
