Stand Up Paddleboard-on foils!

This is the first large cat I know about to adopt "Z" foils as now used on A Cats. Mainly for "skimming" as I understand the article. If it were to foil it would probably require active manual rake control-at least on the windward foil to zero out lift and/or create downforce. It will be interesting to see how this develops.

First posted by Manfred on boatdesign.net(as far as I know) . Can't translate but the sketch makes sense. See below for the video showing a glimpse of this at 33 in:



Summary from Manfred at boatdesign.net : "The tubercle has to avoid the sudden and total loss of lift at the foil."
