Terms by category
Policy Types
(5 terms)Seguro de embarcación
Boat/vessel insurance
General term for insurance covering recreational boats, yachts, and watercraft in Spain. Policies vary based on vessel size, type, and use. Mandatory third-party liability required for all powered vessels.
Why it matters for expats:
Whether you have a small dinghy or a luxury yacht, you need appropriate insurance. The type and level of coverage depends on your vessel's size, value, and how you use it.
Seguro responsabilidad civil náutica
Third-party marine liability
Mandatory insurance covering damage or injury you cause to others while operating your vessel. Required for all powered boats in Spanish waters. Minimum coverage limits are set by law based on vessel length.
Why it matters for expats:
This is the legal minimum—you cannot use Spanish marinas or waters without it. Coverage limits increase with vessel size. Basic policies cover third-party only; you'll need additional coverage for your own boat.
Seguro a todo riesgo náutico
Comprehensive marine insurance
Full coverage for your vessel including third-party liability, hull damage, machinery, equipment, and personal effects. Covers collision, grounding, fire, theft, storm damage, and more.
Why it matters for expats:
Recommended for valuable vessels. Boats face unique risks—storms, grounding, collision, sinking—that can result in total loss. Comprehensive coverage protects your significant investment.
Seguro de casco
Hull insurance
Coverage specifically for the physical structure of your boat (the hull). Protects against damage from collision, grounding, fire, storm, and other perils. Can be purchased separately or as part of comprehensive coverage.
Why it matters for expats:
The hull is often the most expensive component to repair or replace. Hull insurance ensures you're not left with a worthless wreck after a serious incident.
Seguro de motos de agua
Jet ski/PWC insurance
Specialized insurance for personal watercraft (PWC) like jet skis and wave runners. Includes mandatory liability coverage and optional hull/theft protection. PWC have specific requirements in Spain.
Why it matters for expats:
Jet skis are high-risk watercraft with specific regulations. Proper insurance is essential for marina access and legal compliance. Consider theft coverage as PWC are easy targets.
Financial Terms
(4 terms)Valor convenido náutico
Agreed marine value
When you and the insurer agree on your vessel's value at policy inception. In case of total loss, you receive this agreed amount rather than depreciated market value. Common for yachts and valuable boats.
Why it matters for expats:
Boat values can be subjective, especially for well-maintained or customized vessels. Agreed value ensures fair compensation and avoids disputes over what your boat was worth.
Prima náutica
Marine insurance premium
The annual cost of your boat insurance. Premiums depend on vessel type, size, value, age, navigation area, owner experience, and claims history. Payment can be annual or in installments.
Why it matters for expats:
Marine premiums vary significantly. A small sailing dinghy may cost €200/year while a large motor yacht could be €5,000+. Get quotes from specialist marine insurers for best rates.
Franquicia náutica
Marine excess/deductible
The amount you pay toward each claim before insurance covers the rest. Marine policies often have separate excesses for different claim types (hull damage, machinery, theft). Typically 1-3% of vessel value.
Why it matters for expats:
Marine excesses are often percentage-based rather than fixed amounts. A 2% excess on a €100,000 boat means €2,000 out of pocket. Understand your excess structure before claiming.
Período de invernaje
Lay-up period
The period when your boat is out of the water or not in active use, typically winter months. Many insurers offer premium discounts for declared lay-up periods when navigation risk is eliminated.
Why it matters for expats:
If you don't use your boat year-round, declaring a lay-up period can reduce your premium by 10-25%. Coverage is adjusted during this time—make sure you understand any restrictions.
Coverage Types
(7 terms)Salvamento marítimo
Marine salvage
Coverage for professional salvage operations if your vessel needs rescue—towing from grounding, recovery from sinking, or emergency assistance. Salvage costs can be enormous without insurance.
Why it matters for expats:
Commercial salvage operations can cost tens of thousands of euros. Without coverage, you're liable for these costs plus potential wreck removal. Essential for any serious boater.
Remoción de restos
Wreck removal
Coverage for the cost of removing your sunken or stranded vessel. Port authorities can require wreck removal for navigation safety, and owners are legally responsible for these costs.
Why it matters for expats:
If your boat sinks in a harbor or blocks navigation, you're legally required to remove it. Costs can exceed the boat's value. This coverage protects against potentially ruinous liability.
Cobertura de maquinaria
Machinery coverage
Insurance for engines, generators, and mechanical systems. May cover breakdown, damage, and sometimes wear-related failures. Often has separate excess and may require maintenance records.
Why it matters for expats:
Marine engines are expensive—€20,000+ for larger boats. Machinery coverage protects this investment. Note that normal wear isn't covered; maintain your systems properly and keep records.
Efectos personales a bordo
Personal effects onboard
Coverage for personal belongings kept on the boat—electronics, fishing gear, water sports equipment, clothing. Standard limits apply; valuable items may need separate declaration.
Why it matters for expats:
Boats often carry expensive equipment—navigation electronics, diving gear, fishing tackle. Check your coverage limits and declare valuable items. Consider what you regularly keep aboard.
Cobertura de anexos
Tender/dinghy coverage
Insurance for tenders, dinghies, and auxiliary craft used with your main vessel. May be included in main policy up to certain limits or require separate declaration. Includes theft when stored on deck.
Why it matters for expats:
Dinghies are frequently stolen from yachts. Ensure your tender is properly covered, especially if it's a valuable RIB with outboard motor. Check coverage limits and security requirements.
Asistencia marítima
Marine assistance
Emergency assistance services for breakdowns, fuel delivery, towing to port, and minor repairs at sea. Similar to roadside assistance but for boats. Coverage radius and services vary by policy.
Why it matters for expats:
Getting stranded at sea is more serious than on land. Marine assistance can provide towing, fuel delivery, or mechanical help. Check your policy's service range and response times.
Claims & Process
(3 terms)Siniestro náutico
Marine claim/incident
Any insured event involving your vessel—collision, grounding, storm damage, theft, or injury. Report promptly to your insurer and document everything. Maritime claims often have specific procedures.
Why it matters for expats:
Marine claims can be complex. Document damage thoroughly with photos and video. Note weather conditions, witnesses, and circumstances. Report to your insurer immediately and to port authorities if required.
Perito náutico
Marine surveyor/assessor
A qualified marine surveyor who assesses damage to vessels. They determine repair costs, seaworthiness, and whether a boat is a total loss. May be appointed by insurer or independently.
Why it matters for expats:
Marine surveying is specialized. For significant damage, consider appointing your own surveyor alongside the insurer's. Keep all damage visible until assessment; don't make temporary repairs without permission.
Siniestro total náutico
Marine total loss
When repair costs exceed the vessel's insured value or the boat is completely destroyed/sunk beyond recovery. You receive the insured value (agreed or market) minus any excess.
Why it matters for expats:
Total loss is relatively common in marine insurance—boats can sink, burn completely, or suffer irreparable damage. Agreed value policies ensure you receive fair compensation.
People & Roles
(3 terms)Patrón
Skipper/captain
The person in command of the vessel. Insurance policies typically require the patrón to hold appropriate qualifications for the boat type and navigation area. Their experience affects premiums.
Why it matters for expats:
Your insurance may be void if an unqualified person is at the helm during an incident. Ensure all regular skippers hold valid licenses for your boat's category and intended use.
Tripulación
Crew
People aboard who help operate the vessel. Policies may cover crew injuries under personal accident provisions. Paid crew may require separate employers' liability insurance.
Why it matters for expats:
If you sail with regular crew, check they're covered for injuries. Paid crew creates additional legal obligations—professional skippers and crew need proper contracts and insurance.
Pasajeros
Passengers
Non-crew persons aboard your vessel. Third-party liability covers injuries to passengers caused by negligence. Limits depend on your policy and passenger capacity.
Why it matters for expats:
If you take friends or family sailing, they're covered as passengers under your liability policy. If you ever carry paying passengers, you need commercial insurance—recreational policies won't cover it.
Documents
(4 terms)Titulación náutica
Boating license/qualification
Official Spanish boating licenses required to operate vessels. Categories include PNB (basic), PER (coastal), Patrón de Yate, and Capitán de Yate. Required license depends on vessel size and distance from coast.
Why it matters for expats:
Insurance requires valid qualifications for your vessel type. Operating without proper license voids coverage and carries penalties. Foreign qualifications may need validation in Spain.
Matrícula de embarcación
Boat registration
Official registration of your vessel with Spanish maritime authorities. Shows ownership, technical details, and base port. Required for insurance and legal operation in Spanish waters.
Why it matters for expats:
You cannot insure or legally operate an unregistered vessel. Registration also determines which flag you sail under and which regulations apply to your boat.
ITB (Inspección Técnica de Barcos)
Boat technical inspection
Mandatory periodic inspection of vessels to verify safety equipment, structural integrity, and regulatory compliance. Frequency depends on vessel type and age. Similar to vehicle ITV.
Why it matters for expats:
Valid ITB is typically required for insurance claims. Stay current with inspections and address any deficiencies promptly. Inspection requirements vary by vessel category.

Is boat insurance mandatory in Spain?
Yes, third-party liability insurance (seguro de responsabilidad civil) is mandatory for all powered vessels in Spanish waters. Coverage minimums increase with vessel length. Sailing boats may have different requirements.
What's the difference between hull and comprehensive coverage?
Hull insurance (seguro de casco) covers physical damage to your boat's structure. Comprehensive (todo riesgo) includes hull plus liability, machinery, equipment, and often additional coverages like personal effects and salvage.
Why is navigation zone important?
Your policy covers a specific geographic area. Sailing outside this zone—even briefly—can void your coverage. If you plan to cruise to Morocco, the Balearics, or beyond Spanish coastal waters, ensure your policy includes these areas.
What qualifications do I need to skipper my boat?
Spain requires specific licenses based on vessel size and distance from coast: PNB for basics, PER for most recreational boats, Patrón de Yate for larger vessels. Your insurer will require valid qualifications for your boat type.
How does agreed value work for boats?
With agreed value (valor convenido), you and the insurer set your boat's value when the policy starts. In case of total loss, you receive this amount rather than depreciated market value—important for well-maintained or unique vessels.
Does my policy cover my tender/dinghy?
Many policies include tenders up to a value limit. Check your coverage for 'anexos' (auxiliary craft). Valuable tenders with outboards may need separate declaration. Theft coverage usually requires proper securing.
