Boat Safety 101: Navigation Rules

Channel Markers

Like the Driver’s Ed book that you study before getting a license, every boat owner should have a copy of the U.S. Government published Navigation Rules. It is only mandatory that a copy be kept aboard all vessels over 12 meters (39.4 feet) in length.

Knowing a few simple rules can keep you safe on the water. Since there are so many different types of boats, boating activities and styles of boating, it is important to know what to expect when you come upon another vessel and what your obligations are. The Navigation Rules for vessels establish actions for boaters to take to avoid a collision.

The Navigation Rules cover steering rules akin to rules of the road, sound signaling equipment and requirements, and a section on navigation lights.

Proper and safe on-water navigation has many facets, but the most common situation faced when meeting another boat is likely going to be one of the following: a crossing situation, a head-on situation, or an overtaking situation.

 

Boaters should be sure to know all the requirements and etiquette expected of them, including what to do when you encounter commercial vessels, vessels engaged in fishing and diving and law enforcement personnel. At the very least, you should always have a lookout, operate at a safe speed and yield or give-way to another vessel when in doubt to always avoid a collision.

Regulatory Marks and Other Aids

Regulatory marks are designed to assist boaters by informing them of special restrictions or dangers that they are approaching. Regulatory marks are white “can” buoys that have an orange shape on them. The mark will give either a warning or instructions on how to proceed. The shape determines what type of mark it is.

  • A square or rectangular shape is used for conveying instructions.
  • An open diamond shape signifies danger.
  • A diamond with a cross in it signifies an exclusion area that you may not enter.
  • A circle indicates an upcoming operating restriction, such as a speed limit.

Aids to Navigation

Aid To Navigation markers are anything on the water that provides information. They are varied and there is not enough room to get into all their meanings here. For a full description, see the U.S. Coast Guard’s Aids, link below.
