I have seen alot of people back PWC's in there and never had anything said to them. I am not sure if it was just bad luck that day or if the ranger had something against sailboats.
It looks like you are bearing the brunt of the PWCs actions. If you are launching direct into the water, then a ramp should be used. If you are not than anywhere should be fine. Why don't you take the cat off at quiet some distance away and wheel it all the way to the water.
