It usually happens when the wind is up a bit. I cannot explain it though. The rudders just don't work right. I usually have to head up to get them to come out of the stall which slows the boat........not good. Of course, as we have learned, it is due to mast rack. I would tell you where my rack is but I am now running the single forestay setup so it would not help. If I was still running the two bridle wires ( I think they call them that ) I could tell you where the boat stalls out. At what setting.
I guess you could rack the hell out of your mast, like top hole and try it when the wind is 14-15 or so. But you have the shorter mast. Might not work!
