What are COLREGS and the US Inland Rules of the Road? A Guide for Aspiring Boat Captains

Navigating the inland or near coastal waters safely and efficiently requires more than just a boat and a sense of adventure. It demands a thorough understanding of the rules that govern maritime conduct. At Confident Captain, we believe in equipping our learners with the knowledge and skills necessary to excel as Captains. Today, we delve into the COLREGS and US Inland Rules of the Road and explain why the US Coast Guard (USCG) mandates a 90% passing score on their examination and why they require us to do the same as part of our proprietary learning programs.

What Are the COLREGS?
The International Regulations for Preventing Collisions at Sea, commonly known as COLREGS, form the backbone of maritime navigation rules. Established by the International Maritime Organization (IMO), these rules provide a comprehensive framework to prevent collisions between vessels on the high seas and in connected waters. The COLREGS are divided into 41 rules grouped into five parts:

  • Part A – General: This section covers the basic definitions and applicability of the rules.
  • Part B – Steering and Sailing Rules: It outlines the conduct of vessels in various scenarios, including overtaking, crossing, and head-on situations.
  • Part C – Lights and Shapes: This part specifies the requirements for navigation lights and day shapes to indicate a vessel’s status and activities.
  • Part D – Sound and Light Signals: It details the sound and light signals to be used in different situations to communicate a vessel’s intentions.
  • Part E – Exemptions: This section addresses exemptions to the rules under certain conditions.
  • The COLREGS are crucial for ensuring the safety of vessels and their crews by providing clear guidelines for vessel behavior in various maritime situations.

What are the US Inland Rules of the Road?
While the COLREGS apply internationally, the United States has its own set of rules for inland waters, known as the US Inland Rules of the Road. These rules are similar to the COLREGS but contain specific provisions tailored to the unique conditions of US inland waterways, such as rivers, lakes, and bays. The Inland Rules are crucial for navigating these waters safely and avoiding collisions.

Why does the USCG require a 90% Passing Score on a Captains License Exam?
The US Coast Guard requires a 90% passing score on the Captain’s license exam to ensure that mariners have a comprehensive understanding of the COLREGS and US Inland Rules of the Road. Here’s why this high standard is essential:

  • Safety: The primary goal of these regulations is to prevent collisions and ensure the safety of all vessels and their crews. A thorough understanding of the rules minimizes the risk of accidents.
  • Professional Competence: Captains are responsible for the lives and well-being of their passengers and crew. Achieving a 90% passing score demonstrates a high level of competence and preparedness to handle various navigational challenges.
  • Legal Compliance: Compliance with these rules is not just a matter of best practice but a legal requirement. Captains must be able to apply the rules correctly to avoid legal repercussions.
  • Public Trust: The public places their trust in licensed captains to navigate safely. A rigorous examination process ensures that only those with a deep understanding of maritime rules earn the privilege to command vessels.
