Sailing at night under a sky filled to the rim with stars.
Sailing at night with lightning crashing around 360 degrees.
Watching the first glow of the coming sunrise lighten the horizon.
All these big obvious sailing moments can inspire, if not spiritual or religious feelings, at least a reminder of our relative size and importance in the universe.
But then, so can the smaller moments: ghosting along on a sunny afternoon, in light winds on a bay full of sunlight sparkles. Those subtle moments, when the wind that moves your boat isn't massive and obviously powerful, but almost unnoticeable and yet your sails still move you, are simultaneously easier and harder to comprehend. That is where the real magic happens.
