Marina, shipyard and repairer liabilities: risk and insurance map

Last reviewed: 9 August 2026

When a yacht enters a marina, is lifted by a travel lift or is handed to a repairer, contractual liability, third-party damage, property in custody, defective work and pollution can overlap. There is no single answer—or standard policy covering everything. The agreed service, control of the vessel, cause of loss, contract and policy wording all matter.

Start with the service undertaken, not with an assumption of fault

A marina may merely provide a berth, or may also hold keys, move vessels, provide security, haul boats, launch them or supply fuel. A shipyard may build, refit or maintain a vessel. A repairer may work on engines, electrics, hull, coatings or electronics.

Each service changes the duty and exposure. A sound analysis asks:

1. What did the quotation, work order or contract promise?

1. Who had physical possession or effective control of the vessel?

1. What did employees, contractors and subcontractors do?

1. What was damaged, and what caused that damage?

1. Which law and jurisdiction apply?

1. What does each policy cover, subject to its limits and exclusions?

In Spain, Articles 108–116 of the Spanish Maritime Navigation Act 14/2014 govern shipbuilding contracts. Those rules may apply on a supplementary basis to repair or refit contracts when the scale of the work warrants it. Contract law, the Spanish Civil Code and any specific regulation remain relevant.

Practical exposure map

Situation	Potential loss	Decisive question	Insurance section to check
Berthed or stored vessel	Theft, fire, impact, sinking	Was there custody or only use of a space?	Property in care, custody or control
Haul-out, launch or movement	Drop, collision, hull or machinery damage	Who operated the equipment and under what limit?	Travel lifts, cranes and mobile equipment
Repair or maintenance	Damage to vessel, other property or loss of use	Is it rectification cost or consequential damage?	Ship repairers' liability and completed operations
Construction or refit	Defect, delay, trial damage	What obligation and warranty did the contract establish?	Shipyard liability, construction and sea trials
Fire or explosion	Spread to vessels and premises	Where did it start and what controls applied?	Third-party damage, fire and accumulation
Spill or waste	Clean-up, environmental damage or claims	Which substance, activity and legal regime apply?	Accidental pollution and environmental liability
Injury to customer or visitor	Bodily injury and consequential loss	Was a facility defective or an act negligent?	Public and employers' liability, as relevant
Subcontractor	Damage caused by an appointed third party	Who selected, controlled and insured it?	Contractors, contingent liability and recovery rights

This table is indicative. Liability and cover can only be determined from the actual facts, contracts and policies.

Marinas: berthing, facilities and possible custody

The label “berthing contract” does not by itself decide whether the arrangement includes custody. A facility that only assigns a berth may not assume the same duties as one that takes keys, moves the yacht, promises vessel-specific surveillance or carries out other services.

Common scenarios involve pontoons, fenders, mooring lines or shore power; manoeuvres by marina staff; spreading fire; unauthorised access; and storm damage. Allocation may turn on the agreed duty, reasonable maintenance, weather warnings, instructions to owners and causation.

Terms of business should describe the service clearly. A disclaimer or limitation should never be treated as automatically valid or enforceable: wording, negotiation, consumer status and applicable law may change the result.

Repairers: three different types of loss

For repair work, distinguish between:

• Defective work itself: for example, repainting a poorly applied coating.

• Damage to the item being worked on: for example, an electrical error damaging onboard equipment.

• Consequential damage to other property or people: for example, a fire spreading to adjacent yachts.

A policy may treat these categories differently. Some exclude the cost of rectifying the work while providing some cover for resulting damage; others restrict property in care, custody or control. Hot work, testing, navigation, surface treatment, pollution and completed operations also require attention.

The work order should record scope, pre-existing condition, parts supplied by each party, tests, authority for additional work and handover. Photographs, checklists and technical traceability reduce disputes and support the defence of a claim.

Shipyards: construction, refit and latent defects

The Spanish Maritime Navigation Act requires a shipbuilding contract to be in writing and addresses delivery, delay, builder liability and latent defects. Article 113 contains a specific regime that must be read with the contract and applicable time limits.

For major refits, design responsibility, materials, milestones, tests, acceptance, warranties and allocation of risk should be defined. Shipyard liability does not replace builders' risks or cover on the vessel itself; the different policies need to work together.

Travel lifts, cranes and movements within the yard

A haul-out concentrates a high value in a short operation. Sling failure, incorrect placement, mechanical failure or poor manoeuvring can affect the yacht, lifting equipment, workers and third parties.

The risk review should cover equipment capacity and maintenance, operator training, procedures, communications, hull support plans, access control and movement records. The policy should be checked for limits per vessel, aggregate exposure, owned or hired equipment, and damage during movement, lifting, launch and trials.

Fire, pollution and environmental liability

Hot work, lithium batteries, fuels, solvents and electrical connections can create an event extending beyond one workshop. Permit systems, segregation, fire watch, product storage and emergency plans are essential controls.

Conventional civil liability and environmental liability are not the same. Within its scope, Spain's Environmental Liability Act 26/2007 imposes prevention, avoidance and remediation duties on relevant operators. Sudden and accidental pollution cover may not address gradual pollution, administrative costs, environmental restoration or every statutory exposure.

Subcontractors: outsourcing the task does not remove the exposure

Marinas and shipyards use painters, mechanics, welders, electricians and lifting companies. Before access, they should check the declared activity, valid insurance, limits, exclusions, authorised personnel and safety procedures.

Contractual indemnities can allocate obligations, but do not automatically make a liability insurable or prevent third-party claims. They must be coordinated with both parties' policies and site-access rules.

The owner's hull policy does not automatically protect the operator

When a hull insurer pays the owner, it may investigate recovery from the party alleged to have caused the damage. “The yacht is insured” is therefore not an adequate answer. The marina, shipyard or repairer needs its own liability programme and records capable of responding to a subrogated claim.

Nor should an operator assume that a general liability policy covers a vessel accepted for work. Vessel exclusions and care, custody or control provisions are among the most important wording issues.

What an insurance programme should test

Area	Minimum questions
Declared activities	Berthing, custody, repair, construction, lifting, fuel, trials and navigation
Customers' property	Per-vessel sublimit, total accumulation, custody, movement, afloat and ashore
Work	Defective work, resulting damage, completed operations, products and warranties
Equipment	Travel lift, cranes, forklifts, hired equipment and machinery breakdown
Pollution	Sudden, accidental, gradual, clean-up, restoration and territory
People	Public, employers' and relevant professional liability
Contracts	Limits, indemnities, waivers, jurisdiction and insurance obligations
Territory	Spain, work abroad, sea trials and foreign vessels

Limits should reflect both the largest individual vessel and a plausible accumulation. A marina may have dozens of yachts exposed to the same fire or storm; a limit adequate for one isolated casualty may fail under a common event.

What to do after damage occurs

1. Protect people and prevent further damage.

1. Activate the emergency plan and make mandatory notifications.

1. Notify the broker or insurer without prejudging liability.

1. Preserve contracts, work orders, photographs, CCTV, logs, parts and messages.

1. Identify witnesses, employees and subcontractors involved.

1. Do not repair or destroy evidence unless safety requires it and the condition is documented.

1. Coordinate surveyors and communications with the owner and third parties.

Swift action protects the business, but admitting liability or promising payment before reviewing the facts and policy may prejudice the defence.

Frequently asked questions

Is a marina always liable for damage to a yacht at its berth?

No. It depends on the contract, whether custody or other services were assumed, the cause, the marina's conduct and applicable law.

Does liability insurance pay to redo defective work?

Not necessarily. Many policies distinguish rectification of the work from consequential damage. The exact wording must be checked.

Does an insured subcontractor release the shipyard from liability?

Not automatically. Concurrent, contractual or third-party liabilities may remain. The subcontractor's policy and both contracts should be checked.

Is accidental pollution always covered?

No. Time, territory and reporting conditions may apply, with exclusions for gradual pollution or environmental remediation.

Turn the activity map into effective protection

Effective protection begins with a truthful inventory of services, maximum values, equipment, subcontractors and accumulation scenarios. Contracts, prevention and policies can then be aligned. The commercial name of the policy matters less than its definition of activity, exclusions, limits and extensions.

Nautilux Marine Insurance can review the maritime liabilities of a marina, shipyard or repair business against its insurance programme. Request a review of your operation's maritime liabilities before a contractual difference becomes a coverage gap.
