Lots of techie details about the RS Aero foils in this video.
Rudder is glass and epoxy and carbon? Is that good? Will it chip? If so, will it be easy to mend?
So fast downwind they had to design a totally new rudder stock? Really? Faster than all those RS boats with asymmetric spinnakers? Surely not? But I'm glad they did what they needed to do to stop the speed wobble. I hate speed wobble.
But it is really fast downwind. I think the clip at around 0:47 in the video is the broadest reach I've seen in any of the videos of the RS Aero so far and it's smoking.
