Essential Navigations and Seamanship Theory Course – Online course

RYA Essential Navigation and Seamanship


Sunsail offers the RYA Essential Navigation and Seamanship (ENAS) as an online course, making it easy for you to fit your learning around other commitments.

This ENAS online course will give you the essential knowledge needed when you’re afloat, from navigation to safety and seamanship to passage planning.

The course should take around six to ten hours to complete and is ideal for new or inexperienced skippers and crew—whether you’re a sailor, a motor boater, a diver, or a fisherman.

We recommend all ENAS students purchase an additional reading, such as the RYA ICC Handbook along with other Day Skipper theory books.
