Getting around Boston can be challenging if you don’t know where you’re going. The same is just as true on the water. Like the city itself, Boston Harbor is full of obstacles and obstructions. Whether it’s a truck stuck under a bridge on Storrow Drive or a boat stuck on Lower Middle; not knowing the proper route can cause a lot of problems. Using both traditional and new navigation methods, this course is designed to give you a thorough repertoire of the best places to explore, and the spots to avoid. Featuring both on land and on-the-water components, you’ll learn all the secrets to figuring out those age-old (sailing) questions: Where am I? Where am I going?

This course will help prepare students to pass their green flag written test and is taught on one of our cruising vessels.
