Back in the 1980's when I first met my future husband, he taught me to sail. I'd never set foot on a sailboat before then, but I loved it from the very start. The rocking of the waves against the hull, the pressure of the wind filling the sail, the flapping of telltales. Being on a sailboat is a delight for the senses. But it is also a universe with its own rules, language, and skills.
Navigation is a great example of this. There is something odd and counter-intuitive about navigating on a sailing vessel. For one thing, you can almost never go precisely in the direction you want. And you can never ever sail directly into the wind. Then, you have to understand that turning the wheel might mean little if the wind and current aren't with you. Even if you do everything right, sometimes the wind dies and you end up drifting. . . .
