For many years I am thinking and dreaming of a plunging wing watercraft propelled by our ideal rowingbike movement.

You can see the prinicipal technics of a plunging wing watercraft on this video from aquaskipper  

The same principal makes the Canadian Snowbird ornithopter project  fly. Rowingbike participated as partner and sponsor in this project.  In this beautiful video you see several rowingbike parts ( bowsprit, Footslider, yellow  wingwires)

Last winter things were low in Rowingbike production so i had time to start to build an actual model of the technical principle that is not that simple yet as it should become to be…..

here you see some pictures for an impression.
