Video 2: Stop Looking at Wind Maps: How to Actually Read a Forecast (PredictWind 2/5)

The map is not the territory—and a "pretty wind map" is not a passage plan. In this second installment of our 5-part intensive series, we’re diving into the engine room of weather forecasting. After 85,000 miles at sea, I’ve seen how easy it is to trust a colorful screen and sail straight into a disaster. This video is about moving from "looking" at the weather to interpreting it like a professional. We break down where the data actually comes from, why different weather models often disagree, and how to use "Validation" to decide which forecast is worth betting your life on. 📘 GET THE BOOK & SAVE $100 My book "Be The Captain" is the foundation of this entire series.
