Jackdaw sent me the polars for my boat and we are trying to use the chart as we learn to race faster, but I need to understand how to calculate our best upwind and downwind VMG values from this chart. I watched a video on youtube talking about this topic and they showed the fastest points of sail by drawing vectors on the polar chart but didn't explain how they arrived at them.
Can anyone help?
We are in the whitesail class so they don't have us going downwind much but both intrigue me especially since I recently had a big downwind run and the best VMG I could get on the chartplotter was dead downwind which was unexpected.
