Nav Lights & Shapes Quiz 2

Anyone who is responsible for a vessel at sea, from the smallest dinghy to an ocean going supertanker, day or night, must be able to recognise other vessels and quickly interpret what they see around them. This is not always easy, especially in crowded coastal waters.

The Nav Lights & Shapes – Shapes quiz is designed to help all recreational and professional seafarers learn how to identify the vessels in their vicinity and the activities they are engaged in. The lights displayed follow an international code specified by the International Regulations for Preventing Collisions at Sea (ColRegs).
