How much does boat insurance cost? Orders of magnitude and what sets the price

Insurance is a quiet line in a boat’s budget, but it is the one that decides everything on the day of a grounding, a fire in the marina or a theft. Its price ranges from under a hundred euros a year for a small boat insured third-party only to several thousand euros for a large sailboat or catamaran insured comprehensively. This guide gives the orders of magnitude observed in 2026 in price guides published by insurers and comparison sites, in euros including tax per year, then what makes the premium vary and what to read before you sign. These are wide ranges, not quotes: only the insurer’s offer, for your boat and your sailing plans, is binding.

1. Is it compulsory?

In France, the law does not require a pleasure boat used privately to be insured. But whoever causes damage must make it good, and a collision or a fire on the pontoon can be very expensive. Above all, marinas ask for a certificate of insurance in practice before giving you a berth, at least for third-party liability, including refloating and wreck removal if the boat sinks in the harbour. Boatyards and wash-down areas ask for it too. Abroad, some countries or marinas require a specific certificate: check before you leave, along with the entry formalities.

2. The three levels of cover

• Third-party liability: it pays for the damage you cause to others — another boat, a pontoon, an injured person — and, depending on the policy, refloating and wreck removal. It pays nothing for your own boat.
• Intermediate policies: third-party liability plus certain named events, such as theft, fire or storms.
• Comprehensive (all risks): it also covers damage to your own boat, whatever the cause, except for the exclusions written into the policy — grounding, collision, sinking, dismasting, vandalism, theft.

On top of that come options: assistance and towing, legal protection, road trailer, personal effects, tender and outboard, search costs. Assistance at sea without cover can cost several thousand euros.

3. Orders of magnitude

The price guides consulted put third-party liability alone at around €100 to €300 a year for most boats under 10 metres, and comprehensive cover from €300 to €400 a year for a small boat. Beyond that, the premium mainly follows the insured value: two sources put comprehensive cover at around 1% of the boat’s value per year, one of them saying 1 to 2% depending on the boat and the sailing area. Here is what the published ranges give, in euros including tax per year:

For a valuable boat, do the reverse calculation: a sailboat insured comprehensively for €80,000 is more likely to be around €800 to €1,600 a year than at the bottom of the table. Gaps between insurers are wide for the same boat: comparing several offers is not a luxury.

4. What makes the premium vary

• The insured value of the boat and its equipment (electronics, tender, new sails).
• The type of boat: a powerful motorboat or a fast outboard boat costs more to insure than a sailboat of the same value.
• The sailing area: inland waters, coastal, Mediterranean, Atlantic, offshore or tropical. Long-distance sailing or a hurricane zone carries a clear surcharge, when it is accepted at all.
• The use: private pleasure sailing, racing, chartering, living aboard. A chartered boat must be declared as such, otherwise it is often not covered.
• Where the boat is kept: supervised marina, mooring buoy, laid up ashore or in a shed.
• The skipper’s experience and record: licence, years of sailing, past claims.
• The excess you choose: a higher excess lowers the premium, but you pay for the small claims.

5. What to read before you sign

Two policies at the same price can pay out very differently. The points that matter:

• Agreed value or market value. The agreed value is set when you sign and paid as is in a total loss; the market value is estimated by a surveyor at the time of the claim, and falls as the boat ages. Check whether an “agreed” value stays agreed for the whole life of the policy.
• Depreciation. Some policies deduct a percentage according to the age of the damaged parts (sails, rigging, engine, electronics). On an older boat, that scale decides the size of the cheque.
• An insured value set too low. Under-insuring to pay less exposes you to a proportionally reduced settlement, even for a partial loss.
• The excesses: their amount, and whether they apply per claim, per cover or to theft only.
• The exclusions: lack of maintenance, wear and tear, sailing outside the area, boat left unattended, named storm, skipper without the required licence.
• The policyholder’s obligations: some insurers require a survey when the policy is taken out, then at regular intervals for older boats, at your expense.

6. Bringing the bill down without losing cover

• Declare the area you really sail in, not the widest one “just in case”, and adjust it before a long voyage.
• Choose an excess you can pay without difficulty.
• Mention laying up ashore or in a closed building, and a claims-free record.
• Keep proof of maintenance: after a claim, the surveyor will look for whether poor maintenance caused it. Invoices, dates, engine hours and photos answer that question — see which proofs count.

To place insurance in the year’s budget, see how much boat maintenance costs; before buying, add it to the sums with the buyer’s checklist.

7. Getting advice

A marine insurance broker compares several insurers and reads the general terms with you; a marine surveyor establishes the boat’s value and condition when the insurer asks for it. Always ask for the general and specific terms, not just the price.

The Hullteam logbook keeps a dated, sealed record of every job: that is what you will be asked for on the day of a claim as on the day of the sale — see which proofs count.
