If there is a launch area where you can drop off your yak, the new 12' PA should work for you. Buy the h bar attachment for easy in and out and support you while you look for fish and cast to them.
If you don't have long distances to go from the launch site, the Mirage system should work for you without any need for an electric motor.
New to forum, hoping for help. I have a lake here in So Cal that doesn't allow float tubes but allows "sit on top" Kayaks. I want to fly fish from a kayak but I need to be able to move backwards (to be able to strip line in) and control the Kayak. I also need a place for the line to sit (like a stripping apron) but see that with the drive system, it doesn't seem there is any room on deck for that, and you are in a recumbent position. I was thinking of the evolve propulsion as it looks to go backwards. Couple of questions I have are: 1. How long does a charge last if only going slowly? 2. Are there any fly fishers currently using a Kayak for this? Any help or input is greatly appreciated.
