Speed tips seem to focus on deep reaching - turning off the wind for maximum speed downhill. That's great, but I'm mostly interested in crosswind speed as I am fascinated by the Alpha division and want to improve my results at my local spot. Most alpha advice focuses on the turn itself, but seems to pay little attention to the the entry and exit speeds.

So I am asking about what the cornerstones of crosswind speed are. How can I go faster so I can I maximise my entry and exit speeds in gybes, particularly in rough water?
