The RYA defines the Day Skipper / Watch leader syllabus. It includes a comprehensive introduction to chart work, navigation, meteorology and seamanship for those ready to take the next step in their skippering journey and start making decisions onboard.
The list below indicates the depth of knowledge required and the minimum time which is to be spent on each subject area.
A: Full knowledge
A depth of knowledge which is fundamental to safe navigation and good seamanship. The student will be able to apply the knowledge in a practical situation and also appreciates why the knowledge is so important.
B: Working knowledge
Understands what knowledge to apply, when and how to apply it for a particular undertaking. Recognises what their level of knowledge is relative to the given situation. The student is aware that their knowledge is broad but not necessarily deep.
C: Outline knowledge
An awareness of the subject area but only a superficial understanding of its application in practice. The student recognises that further knowledge of the topic will be required in some practical situations and knows enough to find appropriate sources of information for learning.

Easy to follow and access the courses, great to be able to go at your own pace and revisit topics whenever. Thanks so much !
Well designed and easy to follow online course. I managed to complete it on my train commute. The training made the exam very manageable.
Really helpful videos and exercises that take you step by step through what is needed. It was great being able to go through the online course at my own pace and the feedback, both in the exercises and from the instructure, was clear and helpful.
Fantastic day skipper theory course – concepts explained clearly with brilliant graphics, interactive, useful downloads, all whilst being able to complete the course at your own pace. Marcus was very helpful and responsive throughout. I’d highly recommend!
Thanks so much for the fantastic review! We’re chuffed the graphics, interactives and cockpit-ready downloads helped the concepts click, and that the self-paced format worked for you.
