RE: RC Surfer
RC Surfer:
reading your post - I believe your fin was cavitating
- winglets and "fences" on fins help prevent the cavitation (notice the "fences" on shafts of outboard engines)
- very interesting to study cavitation in hydrodynamics.
I got into leaning about it in the early days of windsurfing speed sailing, where we were always pushing fins past their limit
John - hope you get wave in CA
Hugh - working every day on the Red ........ event coming to Maui this winter - top secret!
Silver Surfer is ready for the BIG DROP..........................
