Purpose and Benefit:
Forecasting and withstanding weather conditions are major aspects of cruising under sail and power, whether riding it out offshore, seeking safety in a protected anchorage, or avoiding being too close to a lee shore. 

 

This two day workshop begins with the fundamentals of weather (see Basic Weather Forecasting) and shows how weather satellites and technology have transformed forecasting to show cruisers the best way to combine their own observations with technology. Participants will learn relevant information that will ensure their enjoyment and safety at sea in both foul and fair weather. 

 

BONUS:  This course also includes practical exercises, including a virtual Victoria to Maui transit where students will plot their positions, review weather products and determine the best tactics / weather routing.
