		Richard, 
 That's a fine bit of engineering,  well done. Top marks for a metalwork project ha ha.
 
 It obvious a chunky battery could be on the trailer(s), with a much lighter battery on the dolly for moving her alone.
 
 My thought pattern is an electric winch on a trailer for easy boat recovery, with optional power lead from the car.
 
 A small battery fits in a box on the trailer, just enough power to get the boat on the trailer. A cable from the car provides boost power and charging.
 The trailer could then winch itself towards the car or up a rocky/soft ramp you can't to drive on.
 
 Anyhoo, I look forward to pictures in use.
