After a rented Jet Ski crashes, the rider and rental company may give very different accounts of the dockside instruction. One says the controls were explained. The other says nobody demonstrated how this model turns or stops. The signed form matters, but so do the machine, the instruction actually given, and the rider’s actions just before the injury.
A useful investigation separates those questions. It looks at who operated the personal watercraft, what they were taught, whether the craft and safety equipment worked, and how the collision or ejection occurred.
Check the rider’s age and the safety equipment
R.S. 34:855.3 prohibits operation by anyone under 16. An owner or person controlling the craft may not authorize or knowingly permit underage operation. A parent watching from shore does not create an exception. When the manufacturer supplies a lanyard-type engine cutoff, the operator must attach it appropriately.
The life-jacket provision changed under Act 84 of 2026, effective August 1, 2026. Everyone aboard must wear a personal flotation device, and an inflatable device does not satisfy the rule. The operator may not allow an unprotected person aboard. Check the incident date when evaluating an older rental.
Record each rider’s age, who collected the activation device, and whether people switched drivers. Photograph the flotation device’s label, fit, fasteners, and condition. If the cutoff is relevant, preserve the lanyard and its attachment point. A rule violation may be significant, but the injury claim still needs an explanation of how it contributed.
What did the rental employee show you?
The minimum age to operate and the adult rental exception to boating education are different rules. R.S. 34:851.36(B)(3) applies to renters 18 or older who meet its instruction, materials, contract, and other conditions. A 16- or 17-year-old cannot rely on that adult exception; any other qualification must be checked separately. The livery’s contract-retention minimum is 60 days after rental termination.
Find out which qualification the business relied on for the actual operator. Then ask what instruction occurred. Who demonstrated steering, throttle response, the cutoff, reboarding, operating boundaries, and any braking or reverse features? Was the rider able to ask questions? Did the employee train each operator or only the person who booked?
Keep the explanation specific to the make and model. Personal watercraft do not all have identical steering assistance or stopping features. If the rider says the craft would not turn after throttle release, compare the manufacturer’s manual, actual rider inputs, training materials, and inspection findings. Do not assume that this statement alone proves either a defect or rider error.
Dock video, the employee’s identity, the instructional video version, and witnesses to the demonstration may help resolve the disagreement. A preprinted acknowledgment should be compared with those records.
Reconstruct the movement before impact
The final resting position rarely tells the whole story. Map the launch area, channel, docks, no-wake markers, riding boundaries, and nearby vessels. Record weather, visibility, surface conditions, and the direction each craft traveled.
Ask witnesses to describe the maneuver they saw. Was there a sudden turn, wake crossing, approach toward a fixed object, or attempt to avoid another rider? Someone on shore may have seen separation and course more clearly than a rider thrown into the water. Keep their contact information and let them describe events in their own words.
Request any available GPS records, geofence alerts, speed-control settings, fault codes, and rental-company photographs. These systems vary, so first establish what this craft actually recorded. Preserve original phone videos and messages, including footage from before the crash. A screenshot may omit timing information or surrounding movement.
The machine’s condition belongs in the same reconstruction. Seek maintenance records and earlier damage reports, and arrange preservation before repairs erase the disputed condition. Operator conduct, instruction, and a mechanical failure can contribute to the same event; the evidence should test each explanation.
Read the waiver without letting it end the inquiry
A rental agreement may identify authorized operators, promised instruction, equipment supplied, and the business entities involved. It may also contain a release or a clause choosing another jurisdiction’s law. Keep every page and the electronic acceptance record.
When Louisiana law governs, Civil Code article 2004 restricts advance exclusions or limitations of liability for physical injury. Federal maritime law may affect the analysis. In Great Lakes Insurance SE v. Raiders Retreat Realty Co., the Supreme Court recognized a presumption favoring choice-of-law clauses in maritime contracts, with narrow exceptions. The contract and incident require review before declaring a particular waiver enforceable or invalid.
Either way, the form does not establish that the machine was sound, instruction occurred, or the rider caused the crash. Keep investigating those factual questions while the agreement is reviewed.
Treatment, reporting, and preservation
Get appropriate medical attention and describe the actual mechanism: impact, ejection, submersion, or another force. Keep treatment records and document ongoing restrictions accurately. Follow the applicable agency reporting requirements promptly; an insurance claim is not a substitute for the state incident report.
