An essential part of being a responsible and prudent recreational boater is knowing and understanding the International Regulations for Preventing Collisions at Sea (72 Colregs) and the United States Inland Rules. These two sets of regulations and rules, commonly known as the “Nav Rules” or the “Rules,” apply to all waters navigable by sea-going vessels. The Rules are designed to address vessel traffic scenarios where two vessels are in one of the three approach situations and, to a lesser extent, “special circumstances.” The three approach situations are: Head-On, Crossing, and Overtaking. One of the definitions of “special circumstances” applies when more than two vessels are in a combination of the three approach situations.
The Rules consist of five Parts, five Annexes, and some other “goodies.” The five parts include: Part AGeneral; Part BSteering and Sailing Rules; Part CLights and Shapes; Part DSound and Light Signals; and Part EExemptions. Each part and rule has both an “International” and “Inland” version.
Part A consists of Rule numbers 1 through 3. Rule 1 contains the applicability provisions for the entire Rules. Rule 2 describes the general responsibility provisions and Rule 3 covers the definitions. In this article we will discuss Rule 2 as it relates to the recreational boater. We will then discuss two critical rules contained in Part B: Rule 5 (Look-Out); and Rule 7 (Risk of Collision) as they pertain to the recreational boater. It is important to remember that Part B (Rules 5-10) is applicable to all conditions of visibility.

Rule 2Responsibility, is often commonly referred to the “The Rule of Good Seamanship.” A portion of Rule 2 states the following: “Nothing in these Rules shall exonerate any vessel, or the owner, master or the crew thereof, from the consequences of any neglect to comply with these Rules, or the neglect of any precaution which may be required by the ordinary practice of seaman, or by the special circumstances of the case.”
This basically emphasizes that all vessels, including recreational vessels, are required to comply with the Rules; and blatant disregard for the rules is on its face, evidence of poor seamanship. When a collision between two vessels occurs, including recreational vessels, courts have consistently defined “ordinary practice of seaman” and “good seamanship” to be the same. There have been many landmark collision cases that have served to consistently define these terms.
The first major case, which, to this day, serves as the basis for collisions occurring in the
Keeping a Look Out
Rule 5Look Out. Rule 5 requires that a lookout is to be posted at all times. The purpose of the lookout is to detect, assess and manage riskespecially Risk of Collision. If you, as a recreational mariner, were to be involved in a collision, the test as to a lookout is not just based on a person being aboard assigned to be a lookout; The test is based on if a person onboard is actually performing as lookout. If the answer to that test is no, then there is a clear violation of Rule 5 and therefore Rule 2. Needless to say, single-handers, especially when operating while asleep, operate non-compliant with this rule.
Rule 7Risk of Collision. Rule 7 prescribes how to determine when a Risk of Collision exists. This Rule works integrally with Rules 5 and 6 (Safe Speed.) Rule 7(a) states “Every vessel shall use all available means appropriate to the prevailing circumstances and conditions to determine if Risk of Collision exists. If there is any doubt, risk shall be deemed to exist.”
Basic mariner training, (and therefore the courts), use standard methods to help decide when a Risk of Collision exists. Once Risk of Collision is established, Rule 8Action to Avoid Collision is triggered, vessel rights and responsibilities are established, and collision avoidance rules must be adhered to. It is logical to see that Risk of Collision and the nature of the Risk must be ascertained before appropriate action is executed.
A rather basic method to help establish Risk of Collision is application of the Collision Avoidance Funnel. We can think of situations in which vessels are meeting as occuring in a set of four stages. Stage 1 is when two vessels are far enough apart that no Risk of Collision exists. Stage 2 starts when the lookout and/or operator of the vessel first determines a Risk of Collision is possible. This is often, but not always, concluded by determining if the two vessels view each other at a Constant Bearing and
During Stage 2, each vessel operator must determine whether or not his or her vessel is Stand-On, Give-Way or has Right-of-Way. There is a very significant difference between a vessel having Stand-On versus Right-of-Way privileges! A vessel has Right-of-Way ONLY when traveling down-bound with a following current on the
Stage 3 of the funnel is where Risk of Collision exists and has existed for a relatively significant period of time. Stage 3 is the latest time by which action to avoid collision is to be undertaken. Stage 4, the final stage, is the stage which no mariner wants his or her vessel to encounter. Stage 4 is known as “in-extremis.” Essentially the vessel has little or no time to maneuver and in most cases collision is imminent.
A recent case in point
The inability to recognize Risk of Collision is defined by the Rules and therefore “good seamanship” can often have very serious consequences for recreational boaters. In October 2007, a recreational boat was unknowingly in a Risk of Collision while it approached a tug with a stern tow consisting of barges at night off the
