IRPCS IRPCS


First Principles The International Regulations for Preventing Collisions at Sea (IRPCS) are legally binding on all vessels and apply to all water users.


Additionally, local harbour by-laws cover speed limits, small craft channels, and rules to regulate local marine environments.


The IRPCS rules require all vessels to maintain a lookout at all times by all available means.


Remember to look astern. A sailboat has many blind spots, so more vigilance is required.


All vessels have an absolute obligation to avoid a collision. This applies even if you are the stand-on vessel. You must avoid a collision if the other vessel is not giving way.
