Rules of the Road

The rules governing our time on the water are published in the International Regulations for the Prevention of Collisions at Sea (IRPCS). Sometimes referred to as Collegs (collision regulations), the IRPCS has been adopted by most major countries and legislated in their statute books. Some of the rules have remained the same since 1863.

Anyone going to sea should know at least the basics of the IRPCS, so this module is free for anyone registered on our site.

Skills covered

This module walks through the IRPCS from the ground up. Once completed, you’ll have a sound understanding of the rules, knowing, amongst other things, what to do when you come across another boat on the water, lights, shapes and sounds displayed and what to do in restricted visibility (fog). This module covers the IRPCS in enough depth for YachtMaster®-level theory.

On completing this module, you’ll earn the Collision Regulations insignia!
