Hi guys, I am having trouble going downwind fast. I ride all patrik gear, V2 100 board, foil + 9.0 sail and the patrik race foil 900 wing(not the new aeon). The problem I have is that I can find the sweet spot where you keep accelerating while having a good downwind angle but for a few moments only. Then out of nowhere I loose all power in the sail and have to go a bit upwind and start the process again. Also i cannot seem to go over 24 knots while going downwind. If you guys have any tips that can help me I'd be very greatful. I should also say I do a lot of course racing, not slalom, so deep upwind and downwind angles.

Thanks in advance
