7. General Rules • At first glance the myriad of navigation lights and shapes don't seem to make much sense. Here are a few basic rules to follow to make learning the navigation lights easier. • a vessel will only have red, green sidelights and a stern light when it is underway (i.e. not anchored, moored or secured to a dock); • if a vessel is under power it will have one or two masthead lights depending on it's length (over 50 meters two; under 50 meters one). Since it is underway, it will also have the red, green sidelights and a stern light; • a boat that is anchored, it is not making way and therefore it will only have one or more 360° white anchor lights depending on it's length ( under 50 meters - one anchor light; over 50 meters but under 100 meters - two anchor lights one at the bow and one at the stern; over 100 meters - two anchor lights, one at the bow and one at the stern plus deck lights). Any vessel anchored will display a black disc which is the day shape indicating the vessel is anchored; • a sailboat (i.e. a boat under sail alone) will have red and green sidelights and a stern light but since it is not under power, it will not have a masthead light Endurance Merchant Navy Volunteer Cadets
