I had decided not to attempt Spinny for that reason.
I decided on this rig after watching the Tornado guys on you tube going for top speeds. They only managed 22 knots and spent most of the time trying to manage luffing out power. They had too much power not too little.
I am hoping the mast rake helps with keeping the nose up, the lower mast with center of effort and not dragging so much stuff through the air at that speed and the V creating a steady plane.

But tell me, how did you have the boat set to achieve that speed?
