Competence in seamanship is important for every sailor, no matter their experience. In this series of online classes, we'll cover weather, navigation, safety, mechanical knowledge, and interpersonal skills necessary to be a safe, confident, happy, proficient coastal cruiser.

Bill Gladstone is a great instructor who explains everything clearly and gives practical examples. I learned a lot of new skills and strategies that I can apply to my sailing. Highly recommended!

I enjoyed this online course very much. Bill Gladstone is an experienced sailor and a wonderful teacher. He covers all the essential topics and also shares his own stories and tips from his cruising adventures. I feel more confident and prepared for my next cruising trip.




Cruising and Seamanship draws on a broad and ever changing mix of skills. Over time there have been changes and improvements in sails, boats, and gear; and of course a revolution in electronics and navigation. In this 4-part series, we'll teach you the latest seamanship skills you'll need to face the new and unique challenges each cruise presents.
