  • Is this course right for me?
    This course is designed for sailors and other wind-driven athletes (kiteboarders, windsurfers, etc) that want to gain a competitive edge via simepl to use weather concepts. If you enjoy wind sports on the water and want to step-up your weather strategies to a high-performance level, this course is for you. If you enjoy wind sports for leisure, you will also learn a lot in this course! We will give you the need-to-know weather concepts without any extra complex science. Do I need a background in weather science? No! This course is for all levels and ages, and will cover the knowledge you need to know in an easy-to-digest format using real-life examples. Who is this course NOT right for? If you are looking for highly technical collegiate-level meteorology, this may not be for you, as we don't go deep into the academics, mathematics, or physics.
  • How is this different from other weather seminars or courses?
    What sets this apart from other weather courses is that we focus on teaching you how to apply the weather principles to your race prep strategy. The goal of this course is not to go so deep into the science theories that you end up with a degree in Meteorology. This will be an easy-to-digest course that uses practical examples that any sailor can understand. There are also a variety of ways to learn the material for different types of learners. You can watch the presentations via audio/video or read the text lessons. You’ll apply what you learn in the Live sessions that will have interactive polls and quizzes.
  • How long will I spend on the material each week?
    Estimated weekly time commitment: ~ approx. 1 hour. Chapter videos/readings: plan to spend average 45min-1 hour per week Additionally, live sessions will be approx 1 hr long Zoom sessions, and watching/attending is highly encouraged. (they will also be recorded for you to watch afterwards) Remember you’ll have lifetime access to the content inside the course (including recordings of the live sessions) to re-watch or go back and retake the course as updates are made periodically over the years.
  • How does the online course platform/website work?
    The course is hosted on the platform Thinkific. From Thinkific’s website: "Thinkific is a software platform that enables entrepreneurs to create, market, sell, and deliver their own online courses." Learn more about them here: You will access the player through the sign-in screen at which will require you to create a username and password to access the course. Inside the first lesson of the course, there is a tutorial walkthrough on how to use the online course player, but it is very easy and intuitive. Any Live Sessions will be hosted inside the course platform using Zoom. The Zoom meeting is embedded directly into the course player, so there is no additional meeting link. It is recommended that you create a free account through Zoom to make the process smoother.
