Day Shapes
Day shapes are masthead signals indicating the status of a vessel at sea to other vessels. For your safety and that of your crew, you need to be able to identify different types of vessels via their day shapes, and know exactly what the day shapes signify.
This section contains the most common day shapes you are likely to come across. We have made the images simple, using using a similar format to that which you’ll find on your Day Skipper, Day Skipper Coastal and Yachtmaster exams. Good luck with your studies, and happy sailing!
