Step-by-step checklist
Identify
Hands off until the expert arrives. Nothing at the scene gets touched, moved, repaired, or thrown out until the origin and cause investigator has secured it. Evidence that's moved early can sink the whole recovery.

1. Identify
Common scenarios
| Scenario | Who may be responsible |
|---|---|
| Vessel hits vessel (a collision) | The operator of each boat, by percentage of fault |
| Vessel hits a dock, pier, boathouse, seawall, or moored boat (an allision) | The operator of the moving boat |
| A boat breaks loose and drifts into property | The owner of the drifting boat, or whoever tied it up |
| A large wake damages docks or moored boats | The operator who threw the wake |
| A rented jet ski or pontoon is damaged | The renter (see the next section) |
| A boat falls off a lift or storage rack, or burns at a marina | The marina or storage operator |
| A steering, engine, or electrical failure causes the loss | The manufacturer, or whoever last serviced the boat |
When maritime law applies
Federal maritime law usually governs when the loss happens on navigable waters and involves traditional maritime activity. Recreational boating counts. Navigable waters include oceans, rivers, the Intracoastal Waterway, and lakes that can be used for interstate commerce. A small lake entirely within one state may fall under state law instead, so confirm which law applies first.
The presumptions that help you
| Rule | When it applies | What it does |
|---|---|---|
| Oregon Rule | A moving vessel hits a stationary object, like a dock or a moored boat | The moving vessel is presumed at fault and must prove it wasn't. This is the maritime version of a car hitting a house. |
| Louisiana Rule | A drifting vessel hits something | The drifting vessel is presumed negligent. |
| Pennsylvania Rule | A vessel broke a safety rule meant to prevent collisions, such as speed, lookout, or lights | The violating vessel must prove its violation could not have caused the accident. |
Fault is split by percentage. Maritime law uses pure comparative fault. Each vessel pays its share, even if your client's side was partly at fault.
Responsible parties to consider
- The operator
- The owner, if different, for example for letting an inexperienced person operate the boat
- A rental company, marina, or storage operator
- The employer, for a commercial vessel
- The manufacturer or service company, for a mechanical failure
2. Rented watercraft: jet skis and pontoons
When a renter damages a jet ski or pontoon, the rental company's insurer pays for the repair and pursues the renter.
The rental agreement is your main document. Look for:
- The renter's promise to pay for damage during the rental period
- A damage waiver. Many rental companies sell one that caps the renter's cost at a set amount. Check its exclusions, which commonly include alcohol, reckless operation, leaving the allowed area, towing, or letting an unlisted person drive. If an exclusion applies, the cap usually doesn't.
- The pre-rental checklist and photos, which prove the craft's condition before the rental
- The safety briefing acknowledgment, signed by the renter
- The listed operators, their ages, and any required boater education cards
Where the money comes from
- The renter directly. Renters are often uninsured for this, so direct demands and payment plans are common.
- The renter's own boat or jet ski policy, which may cover rented watercraft
- The renter's homeowner's policy. Many limit or exclude watercraft liability, especially for rented or larger watercraft, so check the policy language before assuming there's coverage.
- A security deposit or card hold, when the rental agreement allows it
When the rental company shares the blame
Expect the renter to argue the rental company caused the loss, with a poorly maintained craft, a mechanical failure, or no real safety briefing. Some states require rental companies to give specific instructions before renting. Get the rental company's maintenance logs and briefing records before sending the demand.
3. Notify and investigate
Get the boating accident report. Under federal rules, the operator must file a report with the state boating authority when damage to vessels and other property totals $2,000 or more, a vessel is lost, or someone is hurt. Property-damage reports are due within 10 days. Request it from the state wildlife or natural resources agency, and get any marine patrol, sheriff, or Coast Guard report too.
Who to put on notice
- The operator and the owner
- Their boat insurer. Recreational boat policies usually carry their own liability coverage, separate from homeowner's.
- The marina, storage operator, or rental company, if involved
- The manufacturer or service company, for a mechanical failure
Evidence checklist
Use a marine surveyor. A surveyor documents the damage, the repair cost, and the vessel's value. The value of the other boat after the accident matters because of the Limitation Act trap in the next section. Hold a joint inspection of the vessels before repairs.
4. Demand, negotiate, and settle
Liability theories
- General maritime negligence, supported by the Oregon, Louisiana, or Pennsylvania Rule where they fit
- Negligent entrustment against an owner who let an unfit person operate the boat
- Breach of the rental agreement, for rentals
- Product liability, for mechanical failures
The Limitation Act trap
Under the federal Limitation of Liability Act, a vessel owner can ask a federal court to cap their liability at the vessel's value after the accident. For a wrecked jet ski or a sunk boat, that value can be close to nothing.
- The owner has six months from the first written notice of a claim to file for limitation. Your demand letter can start that clock.
- The owner can't limit if they knew about or took part in the negligence. An owner who was driving the boat usually has that knowledge, which is your best answer.
- A 2022 amendment removed certain small passenger vessels from the Act. Recreational owners have still used it.
- If an owner files, all claims get consolidated in federal court on a strict deadline. Get counsel involved right away.
Time limits
Maritime personal injury claims have a three-year statute of limitations. Property damage claims are governed by laches, meaning an unreasonable delay that harms the other side. Courts often look to the state's statute of limitations as a guide, so don't count on more time than the state allows. When state law applies instead, the state's deadline controls.
Defenses to expect
| Defense | How to answer it |
|---|---|
| Limitation of liability | The owner's knowledge or involvement, especially if they were operating. |
| Comparative fault | Maritime law splits fault by percentage. A partly-at-fault client still recovers its share. |
| Act of nature, like a storm or current | The Louisiana Rule for drifting vessels, and whether the boat was properly secured or operated for the conditions. |
| State law applies, not maritime law | Whether the water is navigable. This can change the deadlines and the presumptions. |
| For rentals, the damage waiver caps the renter's cost | The waiver's exclusions, and whether the renter broke the agreement. |
Negotiating and settling
Marine insurers are specialists and know these rules well. Lead with the presumption that applies. Review the release with the release checklist, then close with the standard closing letter.
