During a typical weekly around the buoys race, does VMG info from a GPS offer significant advantage compared to deciding the preferred tack "by feel"?
Last week, we didn't have VMG info. The weather was clear--we saw the weather mark. We could see how the start/finish line was oriented relative to the wind and the weather mark. And, "by feel" we decided which tack would be preferred as we started and sailed to the weather mark.
So, what are the pros and cons of trusting the VMG versus doing it "by feel"?
