Anyone who has cruised in way out places that have high tidal rises will know that the biggest pain in the butt is to drag your dinghy (weighted with the outboard) up the beach and above the highwater mark.
Some 10 years ago I bought a pair of dinghy wheels from WestMarine. The two s/s tubular brackets bolted upright onto the transom and the wheels could be lowered/raised as a "slide" inside the "tubes" and set with a s/s pin. The important thing is that the wheels were about 18" diam., and the inflatable
tyres about 8/9" wide. Ideal to pull a dinghy over sand.
Does anyone know whether these are still being made and where they can be obtained.
