This is why I am not a big fan of rowing anything-not to sound condescending. I would rather be dual fishing and utilizing a nice electric motor to move me about with speed and ease....not that there is anything wrong with rowing. It is a great workout and it does take experience and skill to do it and fish.
BTW; I finished up my first electric motor prototype today and I hope to test it this weekend for load and heat ranging...
Think of the lower water versatility of a jetski motor but with 360 degree operation. Plus, remote operation ability or to have the boat relocate with you while wading via remote. Also; the autonomous ability to follow waypoints, hold position, and parallel bank and other structures.
