---------ABOUT THE VIDEO---------

This video was originally uploaded to our other channel, Casual Navigation, back in 2018.

This video is an "in depth" look at Rule 30 of the International Regulations for Preventing Collisions at Sea. This video continues the section looking at Light and Shapes of different vessels. Rule 30 defines the lights and shapes that vessels at anchor and vessels aground need to exhibit.
