Each day of sailing around these islands is unique, from Yata's stormy ride to one day of near calm that required us to motor. Borko, the consummate sailor never took the lazy route of motoring when sailing was an option.
We would determine our course in the morning and depending on the direction and power of the wind we would sail a direct route downwind or tack back and forth with a side or headwind. The day I sailed we had a side wind and I kept trying to get speed but at the expense of the direction we were headed. At one point Borko explained Velocity Made Good. If you sacrifice too much direction for speed you could actually have a negative VMG because you're not actually getting to your desired destination.
Sailing strikes me as something that is ruled by the laws of physics but at the same time is an art. It requires a feel for the boat, wind & water. But it also rewards experience and that is something Borko had ' in spades'.
