Boating accident: what the law requires

Last reviewed: August 31, 2026VerifiedDRNA

In short

Article 8 of Act 430-2000 orders three things after a collision, accident or other emergency on the water. First, help: the operator must give the affected persons the prudent and necessary aid and assistance to save them or minimise the danger, whenever they can do so without seriously risking their own craft, crew or passengers. Second, identify yourself: give your name, address and licence number or the vessel’s identification to any injured person and to the owner of any affected property. Third, report. If there was death or injury, the operator or owner reports within the next twelve hours to the nearest State or Municipal Police station or to the nearest Cuerpo de Vigilantes station when no officer is present; if property damage exceeds one hundred dollars, within the next forty-eight hours. In both cases a written report must also be filed with the Department. Breaching Article 8 is a misdemeanour, and the Department may impose a fifty-dollar administrative fine for failing to report.

What is it?

They are the duties the Navigation and Water Safety Act imposes on anyone operating a vessel or navigation vehicle involved in a collision, accident or other emergency. They are in Article 8, and are complemented by the owner’s civil liability set out in Article 9(6). The Act covers both what has a motor — boats, launches, jet skis, motor sailboats — and what does not — kayaks, canoes, rowing boats, paddle boards, rafts — because Article 8 names both categories.

Who can do it?

Article 8 addresses the operator of the vessel or navigation vehicle involved, and in the reporting part it says “the operator or owner”, so the duty to report also reaches someone who was not aboard. The duty to help carries a limit written into the text itself: it applies whenever it can be done without seriously risking one’s own craft, crew or passengers.

Step by step

  1. Step 1: Helping comes before everything else

    Article 8(1) puts the duty to help first, with a condition worth reading in full: the operator of a vessel or navigation vehicle involved in a collision, accident or other emergency, whenever they can do so, without seriously risking their own craft, crew or passengers, must give the affected persons the prudent and necessary aid and assistance to save them or minimise any danger caused. The Act does not ask for heroics: it asks for what is prudent and necessary, and expressly recognises the limit of serious risk to oneself.

  2. Step 2: Then, identify yourself

    The second sentence of the same subsection is short and concrete: they shall also give their name, address, licence number or identification of the vessel or navigation vehicle, to any injured person and to the owner of any affected property. Those are two distinct recipients, and the Act does not condition this on the other party asking.

  3. Step 3: Twelve hours if there was death or injury

    Article 8(2) sets the first clock. In a collision, accident or other misfortune involving a vessel or other navigation vehicle in which a person is killed or injured, the operator or owner must report it to the State or Municipal Police station, or to the nearest Cuerpo de Vigilantes station where no law-enforcement officer is present. And it adds the deadline: in cases of death or injury, the operator or owner must report within the next twelve hours from the death or injury.

  4. Step 4: Forty-eight hours if damage tops a hundred dollars

    The second clock in the same subsection has a dollar threshold that reads low today, but it is the one the Act sets: where property damage in excess of one hundred dollars is caused, the operator or owner must report it within the next forty-eight hours of the damage occurring. The threshold is “in excess of one hundred”, not “one hundred or more”, and it runs from when the damage occurred, not from when its cost was estimated.

  5. Step 5: The written report is a separate duty

    After setting the two deadlines, Article 8(2) closes with a short sentence that is often overlooked: in addition, a written report on the accident or collision must be filed with the Department. Calling the station does not replace that report, and the report does not replace the call. The Act does not publish the form or the deadline for filing it; that sits with DRNA regulation, which we did not read.

  6. Step 6: What happens if you do not comply

    Article 8(3) carries two consequences that run together. Any person who breaches the provisions of Article 8 commits a misdemeanour. And separately, the Department has the power to impose a fifty-dollar administrative fine for failing to comply with the duty to report. The fifty-dollar fine is for not reporting; the misdemeanour covers any breach of the article, including failing to help.

  7. Step 7: The owner answers even if not aboard

    Article 9(6)(h) shifts civil liability onto the owner in broad terms: the owner of any vessel or navigation vehicle is liable for the damages caused in operating it, where fault or negligence intervenes, and where it is operated by or under the control of any person who, for the main purpose of operating it or having a third party operate it, obtained possession with the owner’s express or tacit authorisation. And it adds a presumption: in every case it is presumed, absent proof to the contrary, that whoever operates or controls the vessel obtained possession with the owner’s authorisation and for that main purpose. Lending the boat does not by itself break the chain.

  8. Step 8: But whoever was negligent must answer to the owner

    The same subsection (h) closes the circle in its second paragraph: the person whose negligence the owner of a vessel or navigation vehicle must answer for, under the previous paragraph, is obliged to indemnify the owner for the obligations and liability the owner had to assume. That is: the owner answers to the injured party, and may then claim against whoever was at the helm.

  9. Step 9: Who is presumed to be the owner

    Article 9(6)(j) sets the ownership presumption that makes the previous two operative: every vessel is presumed to belong to the person in whose name it appears registered, or to the person named in the information given on the identification-number application. That is why transfers and address changes matter: Article 9(6)(c), (d) and (e) require registering the change of owner, reporting the transfer within fifteen days and notifying an address change within sixty.

  10. Step 10: The kayak counts too

    Article 8 always says “vessel or navigation vehicle”, and Article 3 separates the two terms. Subsection K defines a vessel as any water transportation system or equipment with a motor installed, including jet skis, motor rafts, motor sailboats and boats or launches of any class, excluding seaplanes, and including home-built motor-driven structures. Subsection L defines a navigation vehicle as a system able to move on water with no motor installed: paddle boards, rowing boats, canoes, kayaks, sailing boats with or without oars, water skis, floating boards, rafts and inflatable systems. The Article 8 duties reach both.

Where to do it

The immediate report goes to the State or Municipal Police station, or to the nearest Cuerpo de Vigilantes station where no law-enforcement officer is present. The written report goes to the Department of Natural and Environmental Resources, which administers this Act through the Navigation Commissioner. The information on the identity of whoever was operating and the details of the accident also go to the Department.

What to do if something goes wrong

What we did not read and therefore do not publish: DRNA’s navigation regulation, where the written report’s form and deadline live; the federal Coast Guard rules on reporting marine casualties, which run in parallel and which we did not consult; the Traffic Act; and any insurance policy clause. Cost and processing time go unverified because this Act sets no fee and no deadline for filing the report.

Common mistakes

  • Leaving the scene without giving your details: the Act requires giving them to the injured person and to the owner of the affected property.
  • Conflating the two clocks: twelve hours for death or injury, forty-eight for damage exceeding a hundred dollars.
  • Counting the forty-eight hours from when you got the estimate: they run from when the damage occurred.
  • Believing calling the station is enough: a written report must also be filed with the Department.
  • Thinking the threshold is exactly a hundred dollars: the Act says “in excess of one hundred”.
  • Assuming it only applies to motorboats: Article 8 also names navigation vehicles, which include kayaks, canoes and paddle boards.
  • Believing that lending the vessel shifts all liability: the owner answers, and authorisation is presumed.
  • Forgetting the owner may afterwards claim against whoever operated it negligently.
  • Leaving an old address on the register: the change is notified within sixty days and ownership is presumed from the register.
  • Thinking the fifty-dollar fine is all of it: breaching Article 8 is also a misdemeanour.

Frequently asked questions

How long do I have to report an accident on the water?

Article 8(2) gives twelve hours from the death or injury in those cases, and forty-eight hours from when the damage occurred where property damage in excess of a hundred dollars was caused.

Who do I report to?

To the State or Municipal Police station, or to the nearest Cuerpo de Vigilantes station where no law-enforcement officer is present. In addition, a written report on the accident or collision must be filed with the Department.

Must I stop to help even if my boat is in danger?

Article 8(1) conditions the duty: it applies whenever it can be done without seriously risking one’s own craft, crew or passengers. That limit is written into the text.

Who pays if I lent the boat to a friend?

Article 9(6)(h) makes the owner liable for damages caused in operating the vessel where fault or negligence intervenes, including where it is operated by someone who obtained possession with express or tacit authorisation, and it presumes that authorisation absent proof to the contrary. The same subsection obliges whoever was negligent to indemnify the owner.

Does it apply if the accident involved a kayak?

Yes. Article 8 speaks of a vessel or navigation vehicle, and Article 3(L) includes among navigation vehicles kayaks, canoes, rowing boats, paddle boards, rafts and inflatable systems.

What is the fine for not reporting?

Article 8(3) says the Department has the power to impose a fifty-dollar administrative fine for failing to comply with the duty to report, and that any person who breaches Article 8 commits a misdemeanour.
