Sailing best vmg upwind is a problem to me. I realise that the problem could be the course I sail after the gust. I tend to steer down a bit to get lift and maintain speed. But as the true wind is down there is probably nothing to gain. Suppose after the gust the tru wind dies completly. Because of boat speed there is still apparent wind, however how much you steer down the apparent wind will always come from the front. So in true circumstances it is best to limit steering to the most. Anybody wants to comment?
