We were sitting by the slipway watching as a fleet of Optimists and their support boats were recovered from the river when a large rib drive straight towards the slip way, no sight of a trailer or trolley in sight. It didn't stop, instead rose out of the water on three large squashy tyres and proceeded to drive off through the dinghy park, the helmsman in full control.
Closer inspection shows that the rib is fitted with Sea Legs hydraulically operated struts and powered wheels which fold down to provide amphibious capability.
