Well done set up. I am curious ..have you tried your oars yet with the position of your seat. I built my post about 17 inches high. The length of my shin, so I would not have to "crouch" all day long.( I am six four) The result is great if I never have to row...when rowing, the height of the seat(post + 2-3 inches of seat) cause the plane of the oars to not be able to be rowed comfortably with very little stroke being able to be be pulled entirely. I extended the oars, and had some success, but the seat position is still off. I have a shelf, like yours at mid ships..and it is easier to sit on that and row, than to sit in the swivel seat, because the shelf is about the same height as the top of the inflated side tube,about 11 inches. What is your experience? I don't row much...thanks to the great battery center and Minn Kota 40..but occasionally , when approaching the shallow water, or when I have the motor up for launching etc..the whole rowing thing is not a smooth , fun experience in any way.....I could re mount the seat and move it more towards the front, but that puts me farther away from the motor and turning handle...etc.
But I realize the oars were designed for no seat, no floor,sit on the inflatable seat. and row the "raft pool toy" around with no power, so that is a given.....LOL
