Bonaire Lac Bay. Sailworks Retro 7.5, iSonic 107, Black Project FreeDeltaRE 21. Wind: 15 kts
Good workout. The Easter crowd left so the beach was calm and quiet and I shared 'my' part of the bay with two other sailors.
To satisfy the geek in me, I decided I needed a metric to track improvement (if any). I arrived at a form of efficiency metric where the nominal wind speed is subtracted from the GPSTC numbers so that increased wind isn't the only contributing factor to improved numbers. Below is a graph of this metric for the 5x10 values. Per this chart, I have improved. I included two trend lines (linear and 6th order) to make improvement (or not) easier to see.
