I came across a single axle trailer that belonged to a static caravan, I thought perhaps to convert it into a trailer for my Hurley Felicity. It needed some work of course, but the trailer was in good condition. It had the base of the caravan still fixed a floor of thick ply wood this would need to be removed as the sea would use it as a rudder and perhaps tilt the trailer with the fast tides races we have. There was lights connected but no jocky wheel and I was not sure about any brakes! The trailer was about 20ft the same size as the boat. In the end I decided I did not need it yet, perhaps after the sailing season is over and perhaps a single axle is not the most stable, but I think it would be good enough for pulling the boat to/from the mooring twice a year.
