Accident or Collision at Sea During a Boat Rental: What to Do

Hitting a rock, colliding with another boat, a minor injury on board: what to do within the hour, who to call, and how it plays out with insurance.

It's the incident no one wants, and it thankfully stays rare: a knock against an uncharted rock, a collision with another boat approaching a crowded anchorage, or a passenger who takes a minor fall and gets hurt. Unlike an ordinary mechanical breakdown, an accident almost always involves a third party, visible damage, or an insurance question — here is the order of operations, so a stressful moment doesn't get worse through haste.

Make people safe first, then the boat

Before anything else, check that no one on board is injured and that the boat isn't taking on water. Put life jackets on if that hasn't already happened, cut the engine to avoid making any damage worse, and steer clear of a busy channel or anchorage if the boat is drifting. A knock that looks minor from the deck can still have damaged the hull below the waterline: check the bilge and the sump as a matter of course, even with no visible leak from above.

Call for help if the situation genuinely calls for it

A serious injury, a boat taking on water, a vessel that no longer answers: 196 from a phone, or channel 16 on the VHF, reaches the coastguard (in France, the CROSS), which coordinates rescue at sea, volunteer sea rescue included. A "Mayday" call (life-threatening distress) or "Pan Pan" (urgent but not immediately life-threatening) is enough to trigger the right response; our VHF and safety at sea guide covers the exact wording. Outside a genuine emergency, this isn't the right contact — the operator takes over for anything concerning the boat itself.

Collision with another boat: never leave the scene

Just as on the road, motoring off after contact with another vessel exposes you to far more serious consequences than the accident itself. Stay put, exchange details with the other crew (name, the boat's registration number, their insurer or operator's contact if theirs is a rental too), and note the time and position — the boat's GPS or a phone's is enough. If tempers rise, stick to the facts and let both parties' insurers sort out fault afterward.

Document everything before heading back to port

Photos and video of the damage, from several angles and dated where possible, are worth far more than an account pieced together afterward — the same reflex we recommend in our guide to a boat that doesn't match its listing. Also note the details of any witnesses on nearby boats or ashore: their account can carry real weight if fault is disputed later.

The maritime accident report: less routine than its road equivalent

A European-style accident report form does exist for recreational boating, issued by French insurers, but it's carried on board far less systematically than its car equivalent — ask the operator whether they have one at the briefing, before any incident happens. Failing that, a written account signed by both crews, covering the facts, the time, the position and a rough sketch of the manoeuvre, serves much the same purpose with insurers.

Contact the operator and your insurer without delay

The operator remains the first point of contact, accidents included: they're the one who triggers their own fleet insurance and arranges a replacement boat if needed. Reporting to the insurer generally follows a short deadline after the event, typically a few business days unless the contract states otherwise — worth checking in the rental contract's clauses before you leave rather than at the moment of the incident. Reporting late, even with no bad intent, can complicate the claim.

Deposit and excess: who pays for what

Damage recognised as accidental and not the renter's fault is in principle covered by the operator's insurance, up to the excess set in the contract; the deposit held at departure exists precisely to cover that excess if a genuine claim arises. Our guide to the deposit and insurance covers what usually stays the renter's responsibility — particularly when the accident stems from a careless manoeuvre rather than a genuinely independent mishap.

Budget and comparison

Coverage in the event of an accident varies noticeably from one operator to another, and not only by booking platform: excess amount, cover ceiling and how responsive the assistance is are all worth comparing before you pay, just like the headline price.
