Interesting. At a recent regatta we found that the boat was massively over powered downwind and that in big breeze all it want to do was got to china. In desperation I decided to use our standard big breeze upwind settings, downwind. Thats max downhaul, zero rotation . This had a huge effect, it was faster (reduced drag?) and could sail deeper and made the boat semi-controlable. I didnt get alot of time to look at the mast, but it didnt break and if it was ever going to it would have been then! Only problem was the gooseneck got pretty much destroyed.
