GreenCat 605 with retractable electric propulsion

Thank you Gideon for all the additional information.
Is the cat at 17 Kkg in the video, because the waterline is about one ribbon equivalent from the black one or is it just light for the sea trials? If so it would be interesting to learn the performance numbers for its intended weight.
From the figures you gave I estimate the clearance with the bridgedeck to be about 1 m then?
There is a good case to be made for your swing keels. OTOH I do not feel comfortable (yet) about some consequences. I suppose there is too little perturbance in the flow between the hulls to increase the interhull interference.
But I do not want to high-jack a thread in the hybrid subforum.
Thanks again. Luc

Hallo Brian

the boat was actually heavy with 13 people on board and full water and diesel
the weight was more like 18000 during those trials
The bridgedeck clearance is measured at 1.25 with that load
so far the performance is slightly better than what the polars indicate

Regards

Gideon
