I was just out practicing today, solo with the spinny and had my GPS on board, got it up to 17.3kts on one spin run.

Great fun, good gusts, only stuffed it to the mast once and didn't flip at all, you should have come over here Pete, supposed to be more of the same tomorrow. Of course the lake was pretty flat, not like the big waves in the ocean when the wind is up, that helped.
