The trouble with that system is it doesn't really work until the weight has been shifted to the back of the trailer. What you really need is a hydraulic ram which allows you to tilt the bed thus allowing the boat to slide off. Even better, powered by an electric pump with a remote control so you can do it single handed. Don't see why it wouldn't work on a twin axle. In fact, it would be the same sort of setup as on some tilting bed car trailers.
