ColRegs - nav lights and shapes

Wed, 08 Feb 2012 15:17 GMT

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.

ColRegs: Nav Lights and Shapes App

This is not always easy, especially in crowded coastal waters.

The Nav Lights & Shapes app from iGlimpse 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 and day shapes displayed follow an international code specified by the International Regulations for Preventing Collisions at Sea (ColRegs).

Using the app:

There are four main sections of the app: Nav Lights, Day Shapes, ColRegs, and Test Yourself.

Nav Lights:

Nav lights are more complex and have greater variation than day shapes so there is a nav lights basics section to help with fundamentals. There are graphics with drop down captions to help explain the basic rules for power and sailing vessels.

The remaining sections cover categories of vessels defined in the ColRegs. Graphic examples of different light combinations in each category are included, with drop down captions reproducing the appropriate rule for each example.

Day Shapes:

Graphic examples of each type of day shape are shown, with drop down captions reproducing the appropriate rule.

ColRegs:

The International Regulations for Preventing Collisions at Sea Part C: Lights and Shapes (Rules 20 to 31) is reproduced in full.

Test Yourself:

A series of multiple choice questions with graphic representation of lights helps you check your knowledge.
