Who is responsible for avoiding a collision between two boats?

6 Nov 2023

In a word, it is the responsibility of the individuals operating both boats to avoid collisions. This implies that anyone piloting a boat has an obligation to exercise reasonable caution in order to avoid crashes.

If you own a boat, it is your obligation to avoid an accident by always being aware of your surroundings, keeping your speed at a safe level, and taking the required precautions.

This is true whether you are sailing on large seas, crowded harbors, or narrow passageways.

You have arrived to the right place if you are prepared to take a boat exam or simply want to know who is responsible for preventing a collision between two boats. Boating can be a thrilling and fun pastime if done correctly; nevertheless, it also contains the potential of harm.

One of the most serious risks that boaters confront is getting involved in a collision. A collision occurs when one of your boats, another boat, or a fixed or floating item, such as a buoy, pier, or rock, collides with your vessel.

Accidents can have serious repercussions, including death. As a result, it is critical to have the knowledge necessary to avoid catastrophes while out on the water.

Whose Fault is a Collision Between Boats?

Consider it from this angle, but it may be difficult for some boaters to see at first how it might be their responsibility if it was obviously someone else's mistake.

You are sailing on a slender fishing boat in the direction of a large freighter that is estimated to weigh more than 100 tons. You are being pursued at full speed, yet legally speaking, you have the right to flee the scene.

Are you going to stay put just because the other boat made a mistake? Or are you going to try to maneuver your boat out of the way of another vessel that will figuratively smash it into a million pieces? You will be moving to a new location.

To be responsible for anything, you do not necessarily need to be at fault. It is best to worry about whose fault it was later on when everyone is safe and to focus instead on doing the right thing, which is to avoid a collision at all costs, when the possibility of causing damage to property, personal injury, or even death is there.

Boat Collision Avoidance: Who’s Responsible?

The International Regulations for Preventing Collisions at Sea (COLREGS) established by the International Maritime Organization are quite clear regarding who is responsible for ensuring that vessels do not collide with one another.

Rule 3 of the international guideline states that the owner of a vessel, its master (or captain), or its crew is responsible for ensuring that the watercraft does not become involved in a collision and that they adhere to the standards of seamanship.

Some people might argue that crewmates do not have the same level of knowledge and expertise as a skipper. After all, the captain of the boat is the one who is authorized to operate the watercraft, and they wouldn't have that power if they didn't meet the requirements for boating safety and any other legal regulations.

The captain of the boat bears the primary responsibility for avoiding collisions at all costs. In the event that the captain is unable to carry out his duties, the second-in-command can step in and assume control of the situation.

Understanding Boat Collision Responsibility:

The skipper's primary duty is to watch out for other boats and vessels while they are out on the water. However, other institutions also have important duties to play in maintaining the safety of navigable waters.

1. Role of boat operators:

Boat operators, sometimes known as skippers or captains, are the individuals responsible for steering a ship. They are the directors, managers, and chief executive officers of the watercraft, and it is their responsibility to ensure that everyone working for them follows directions in order to ensure a safe journey.

When it comes to avoiding collisions between ships, vessel size is irrelevant. Unsurprisingly, the response to the question "What should a cargo ship captain do?" is the same as the response to the question "What should a PWC operator do?"

2. Role of boat manufacturers:

In spite of the fact that the IMO's COLREGS 72 does not emphasize the responsibilities of boat manufacturers in preventing vessel collisions, we are nevertheless able to identify the roles that boat businesses play based on the various rules.

For instance, keeping a watchful eye on the waterways requires a platform that is high enough to allow a member of the crew to "perch" on and act as a lookout in a secure manner. Communication systems must also be available so that the lookout can alert the captain who is stationed on the bridge in the event that the ship needs to avoid collisions.

In addition, boat manufacturers are required to install dependable navigational aids in their products, such as a global positioning system, a magnetic compass, radar, and sonar.

There is only so much that a boat captain can do to avoid collisions. Therefore, it is the responsibility of the boat maker to ensure that the vessel is seaworthy and is equipped with safety measures and equipment that will provide a more secure journey.

3. Role of regulatory authorities:

Maritime authorities, such as the United States Coast Guard and local transportation agencies, are tasked with the responsibility of enforcing navigation rules, such as COLREGS 72 and state laws pertaining to boating.

The enforcement process includes doing routine checks on the seaworthiness of vessels and ensuring that captains and their crews adhere to all applicable national and international regulations.

4. Role of boating associations and organizations:

Even though it is not their role to enforce safety regulations, boating groups can still provide their members (skippers, captains, and owners of boats) with the knowledge and skills necessary to reduce the likelihood of suffering an accident or injury when operating a watercraft.

Every organization conveys to its members both its vision and its mission. Training, ongoing education, and providing assistance to members are often the primary focuses of most associations' service offerings. The American Boating Association and the American Boat and Yacht Council are two examples of organizations that cater to the boating community.

Factors Influencing Boat Collision Responsibility:

Finding out who or what is to blame for a collision between two boats can be a difficult and time-consuming task. There are a large number of factors to take into account, not to mention the individual legislation and rules that are in place in each state.

Having stated that, the following are some factors that are common contributors to the assignment of responsibility in any accident that occurred at sea:

1. Guidelines for Sea Travel:

Boaters need to be aware that every body of water has its own set of rules and regulations that control how boats can be operated. The correct methods of navigation are outlined below in these regulations. In the event of a collision, the violation of certain rules (i.e., right-of-way, speed restrictions, and overtaking practices) might have an effect on who is held responsible for the accident.

2. Witnesses and evidence will be presented:

Both the testimonies of witnesses who were there and the evidence that was captured can provide useful insight into the events that led up to the incident. Statements made by witnesses, photographs, and videos, together with other types of evidence, can all be helpful in establishing the order of events and deciding who is to blame.

3. Pace and the Distance:

Both the rate at which the boats travel and the distance that separates them can play a role in determining who is responsible for what.

When two boats are operating in the same general region, for instance, one of the boats may be held accountable for a collision if the other boat travels at an unsafely high speed or fails to keep a safe gap between itself and the other boat.

4. Absence of care:

It is deemed that a boat has acted negligently if it fails to use the reasonable level of care that would be expected of it, which then results in injury or damage to another party. A few prominent instances include operating the boat in an unsafe manner, failing to keep an adequate lookout, or breaking one of the boating rules. In the event that the risky actions cause a collision, negligence will play a role in determining who is responsible for the incident.

Frequently Asked Questions:

1. What should I do if I witness a boat collision?

Witnessing a boat collision requires the boat operator to ensure their safety before proceeding to the accident site. Assessing the situation is crucial before calling the Coast Guard or emergency services.

2. What role do navigational aids play in collision prevention?

The ability of vessels to raise their situational awareness over the wide expanse of the ocean and other bodies of water, including waterways with heavy traffic, is made possible by navigational instruments, which contribute to the improvement of boat collision avoidance.


Who is responsible for avoiding a collision between two boats? Although the captain, operator, or skipper of the vessel is primarily responsible for preventing boat collisions, everyone on board is required to be vigilant of their surroundings and report any "undermining" circumstances as soon as possible.
