Navigation Safety is based almost completely on the Regulations for the Prevention of Collisions at Sea (“ColRegs“). We strongly recommend you get a study guide to help interpret and understand the rules and legalese. In addition you will need to read Chapter VIII of the STCW Code.
The exam does test you on Canadian Modifications, so you will need to make sure that you are aware which rules have modifications and what they are.

Colregs Guide This is a good guide, with full colour illustrations. It is useful for the novice seeking understanding and explanations, or for the professional just looking to brush up before an exam.
A Seaman’s Guide to Rule of the Road This is more of a quick reference book, and is well suited to experienced mariners looking to brush up on their knowledge.
