I would agree with Everything PPenman said. As you can see from the Photos it is very easy to build once you follow the instructions. I park a 7.8m Ribcraft on it and it is a breeze to drive on.
However do not expect to hop in and reverse it off. No chance! So I constructed my own reverse winch system. I bought two sailing blocks, a length of 10mm strong nylon sailing Rope (the sort that hardly stretches) and a http://www.amazon.co.uk/Silverline-5...495802-0690008
hand winch. I am now able to winch it onto the dock so that is out of the water and back again (without help) without the winch I cannot move it.
I am delighted with the product as the boat remains dry.
