You can analyze, even over-analyze sailing, by breaking it down into the scientific principles involved. You can study the Beaufort scale of wind speed, the principle of lift which pulls the boat through the water rather than pushing it, the many kinds and purposes of knots, the charts with all their legends and hieroglyphics, and the intricacies of sail trim. All of those can make you a better sailor, but it's for nothing if you can't merely experience the joy and mystery of the wind on your face and your sail. Sailing can't be explained by the scientific principles behind it. It's a mystery.  It was just this kind of mystery that Jesus pointed out to Nicodemus in John 3.
