Mary,
I have stayed with you and Rick before. You do have a good size hill to get up to the grassy area. Not sure about waterproof. I have to work out the motor and gearing then build a waterproff box with seals.

My thought it to attach a small 12 volt wench with a slig to Dune Dog to pull the boats up on the frame. I am still working on the prototype frame and motor. I will keep you posted.

Thanks,

Mike Shappell
