The Marinetta was a concept trailer made by Toyota and shown during the 1971 Tokyo Motor Show behind the RV-1 concept car.
The bottom half was a conventional single axle small trailer made from fibreglass. For the exhibit, it was shown with one inflatable tent next to it and another tent packed inside. The top half of the trailer was a small boat mounted upside-down, with the bottom half of the trailer matching the boat shape along their joining edges. The boat used an outboard motor that was could be disconnected and stowed in the bottom half when the halves were reassembled for towing. The exterior was painted white with a black stripe and the interior was painted bright orange.
A jet ski and its trailer were also shown alongside the Marinetta at the show stand.
