Global boat insurance in 2026: who insures, who declines, and what cannot be covered

Vessel Forensic · Research compiled July 2026

The marine leisure insurance market is coming off several years of contraction. After Hurricanes Irma, Maria, and Harvey in 2017, followed by Ian in 2022 and consecutive active Atlantic seasons, underwriters absorbed enormous losses. The result has been a sustained hard market: premiums rising, capacity shrinking, and entire classes of vessel or geography dropped by carriers who previously wrote the business without hesitation.

As of early 2026 the picture is mixed. Hull and machinery markets are cautiously softening for clean risks: no claims history, newer vessels, inland or low-exposure waters. But recreational marine insurers remain focused on unfavourable loss trends and catastrophe modelling that shows increased frequency and severity of storms. Several generalist insurers have exited marine lines altogether. The excess and surplus markets are filling the gaps, but with tighter terms.

Key dynamics shaping the 2026 market:

• Capacity withdrawal: roughly half of the marine insurers active a decade ago have exited boat insurance, consolidated, or stopped writing new policies in storm-exposed geographies.
• Underwriting beyond hull condition: insurers now scrutinise maintenance backlogs, electrical system age, seacock condition, hose integrity, and service records, not just structural soundness.
• Multihull exclusions: several large US direct writers are widely reported to have stopped quoting multihull sailboats. Progressive's own published limits fall to 35 feet and $175,000 of value in some hurricane-prone states. Multihull appetite in the Australian market has narrowed sharply.
• Superyacht squeeze at Lloyd's: several syndicates left yacht insurance after the 2017 to 2018 losses. The remainder apply severe scrutiny, and vessels valued under EUR 3 to 10 million often struggle to find interested underwriters.
• Climate repricing: vessels kept in Florida, Texas, the Gulf Coast, and parts of California face the steepest premium increases and the most restrictive terms.

Leading insurers by market

North America. Progressive is the largest US boat insurer by market share and the broad-value pick to 50 feet and $500,000. Chubb leads on high-value yachts. Markel specialises in fishing boats, personal water craft, and commercial charters. BoatUS/Geico carries strong membership benefits but is widely reported to have stopped quoting multihull sailboats and boats over 50 feet. Hagerty covers classic and collector vessels on agreed value. Novamar is one of the few brokers willing to quote steel hulls, older boats, and liveaboards that mainstream carriers reject.

United Kingdom. GJW Direct brings over 200 years of marine experience and covers UK and European waters. Admiral Marine, founded by a yachtsman, handles worldwide cruising with a 94 percent renewal rate. Topsail covers UK, European, and bluewater cruising and partners with the Cruising Association and Ocean Cruising Club. Pantaenius, the German-origin European specialist, offers bespoke worldwide contracts and one of the few strong charter products for multihulls. Craftinsure is the flexible online entry point for newer owners.

Europe and international. Pantaenius leads European yacht insurance. AXA XL, AIG, Zurich, and Allianz Commercial write international marine hull and liability, and several UK retail brands are underwritten by the latter two. Gard of Norway is the world's leading P&I club. Gallagher tailors vessel, yacht, and superyacht cover from London.

Australia. The market has become particularly restrictive. The commonly cited uninsurable boxes are wooden vessels, non-marina pole moorings, ex-commercial vessels, boats over 30 years old, and storage in cyclone areas. NRMA and RACQ are reported to be among the few still writing new multihull policies, often at 1.5 to 2.5 times the previous owner's premium.

What cannot be insured

No published industry blacklist exists; insurers use internal underwriting guidelines that vary by carrier. But the following categories consistently face refusal or extreme difficulty across multiple markets.

Ferro-cement hulls are the clearest case of near-universal uninsurability. Build quality was inconsistent (most were amateur-built during a 1960s and 1970s fad), internal rebar corrosion is invisible until catastrophic, impact resistance is poor, and near-zero resale value makes agreed value policies commercially unviable. Third-party liability can sometimes be obtained; comprehensive hull coverage is essentially unavailable.

Wooden vessels face significant but not total barriers. Specialists will cover well-maintained classics, but wooden boats over 30 years old without a recent, positive survey from a specialist wooden boat surveyor are declined by most mainstream carriers.

Steel hulls are insurable but face a reduced pool of underwriters, higher premiums, and a requirement for ultrasound thickness testing. Older steel hulls kept on pole moorings or without documented corrosion protection are regularly declined.

Fibreglass is by far the most insurable hull material, but documented osmosis brings coverage restrictions or remediation requirements before a policy is issued.

Age is the largest factor after hull type. Under 10 years: insurable almost everywhere, often without a survey. From 10 to 20 years: a Condition and Value survey is usually required. From 20 to 30 years: the pool of willing underwriters shrinks and maintenance records join the hull as decision points. Over 30 years: many mainstream carriers decline outright, and industry commentary after the 2022 hurricane losses put the number of carriers exiting boat and yacht coverage at roughly half, with the survivors strictest on older vessels.

Home-built and amateur-built vessels of any material face near-universal rejection. Ex-commercial vessels converted to leisure use are routinely declined. Liveaboards are among the hardest categories of all; large direct writers refuse the use outright and coverage sits with specialty carriers at substantially higher premiums. Hurricane-zone storage brings named-storm deductibles of 5 to 10 percent of hull value where coverage exists at all, and war risk zones require separate cover with pricing that changes daily.

The multihull problem

Multihulls occupy a uniquely difficult position in 2026. Several large US direct writers are widely reported to have stopped quoting multihull sailboats, from small trimarans to 50 foot cruising catamarans, and Australian carriers' multihull appetite has narrowed sharply, with individual declines widely reported even for vessels insured under previous owners. Admiral Marine in the UK requires a year of ownership experience before covering a catamaran.

The resistance comes from claims data rather than seaworthiness arguments: Caribbean charter fleet claims out of proportion to the multihull share of insured vessels, higher salvage and haul-out costs driven by beam, fewer repair facilities that can take the width, bridgedeck slamming as a multihull-specific failure mode, and hurricane losses concentrated in charter fleets that bled into underwriting models for all multihulls. Trimarans are commonly classified as racing boats regardless of intended use.

Production catamarans from established builders (Lagoon, Fountaine Pajot, Leopard, Bali, Catana, Privilege, Outremer, Seawind) with clean survey histories remain insurable through specialist brokers at higher premiums. Custom and one-off multihulls are the hardest category. Specialist sources still writing multihull business include International Marine Insurance Services, Suncoast Insurance, Novamar, Pantaenius, Topsail, and Craftinsure.

What surveyors decline, and what triggers rejection

Marine surveyors are the gatekeepers between a vessel and its insurer. Some will refuse to inspect at all: ferro-cement hulls, in-water-only surveys where the vessel cannot be hauled, and vessels whose preliminary inspection reveals obvious structural compromise.

The 2026 environment has expanded the list of rejection triggers well beyond structural failure:

• Electrical systems: outdated or non-standard wiring, missing circuit protection, undocumented DIY modifications, and lithium battery installations without a proper battery management system and isolation.
• Seacocks and through-hulls: corroded or seized seacocks are now a common basis for refusal. Insurers are no longer willing to pay catastrophic flooding claims caused by a component that costs less than 50 pounds to replace.
• Hoses and clamps below the waterline: degraded or incorrectly secured hoses bring conditional coverage or outright refusal.
• Standing rigging: wire rigging over 10 to 15 years old without documented replacement increasingly triggers conditions or refusal, particularly for offshore use.
• Engines and fuel systems: corroded exhaust risers, undocumented hours, corroded tanks, missing shut-off valves.
• Osmosis: moisture readings above threshold can suspend coverage until remediation, which can run from 10,000 to over 50,000 pounds.
• Maintenance documentation gaps: the defining 2026 shift. A vessel that presents well and passes a traditional structural survey may still be declined if the critical systems maintenance history is absent.

Underwriters have concluded from their claims books that most expensive losses originate not in storms or collisions but in the failure of small, replaceable, neglected components. The burden of proof has moved to the owner's records, and it transfers to the buyer the day the boat changes hands.

Luxury yachts and superyachts

The superyacht market contracted severely after 2017 and a cluster of high-profile losses. Lloyd's instructed its syndicates to clean up marine underwriting, several exited yacht insurance entirely, and premiums rose sharply. As of 2026 the market is stabilising: European insurers have moved into the vacated space, and clean risks are renewing flat or with small single-digit increases.

Hard-to-place segments remain: vessels above EUR 80 to 100 million (single-vessel losses exceed any one insurer's appetite), older superyachts with high operating costs against depreciating hull values, and vessels cruising high-risk areas. The awkward gap is EUR 3 to 10 million: too expensive for recreational carriers, too small for superyacht specialists.

Benchmarks: roughly 1 percent of hull value annually for a clean risk in low-exposure waters, rising to 1.5 to 2 percent or more for hurricane zones, charter use, or a claims history. Annual maintenance, separate from insurance, runs around 10 percent of vessel value.

The uninsurable spectrum, ranked

1. Ferro-cement vessels: near-universally declined for hull coverage
2. Home-built and amateur-built vessels: declined by virtually all mainstream carriers
3. Custom-design multihulls: declined in Australia, extremely difficult elsewhere
4. Wooden boats over 30 years without specialist survey: declined by most mainstream carriers
5. Any vessel over 30 years in a hurricane zone: most carriers will not quote
6. Liveaboards: very few carriers write the policy at all
7. Steel hulls over 30 years without ultrasound testing: declined by most
8. Ex-commercial vessels converted to leisure: routinely declined
9. Production multihull sailboats: reported blanket exclusions at some majors, specialist cover still available
10. Fibreglass vessels of 20 to 30 years with maintenance documentation gaps: increasingly declined
11. High-performance vessels: limited carrier pool, higher premiums
12. Lithium battery installations without documented management systems: conditional coverage or refusal

Lowering the premium: what the owner controls

The hard market has a flip side. When underwriters ration capacity, they price for uncertainty, and the owner who removes the uncertainty gets the better terms. Brokers consistently report the same levers. A clean five-year claims record is the strongest single pricing factor. A current out-of-water Condition and Value survey, with evidence that the surveyor recommendations were completed, moves both acceptance and price. A formal qualification such as an RYA or USCG certificate typically earns a discount. A marina berth prices below a swinging mooring. A declared cruising range matched to actual use prices below a wide one.

Above all of these sits documentation. Underwriters who once asked only whether the hull was sound now ask for engine service history, standing rigging replacement dates, seacock and hose service records, and battery installation details. Most owners cannot produce that file, so they are priced as unknowns. The owner who presents a complete, dated record of every major system, its age against design lifespan, and what has been replaced is quoting from the documented end of the market. That is the file a Vessel Forensic audit produces. Insurers do not discount for the audit itself; they price the certainty it evidences, and certainty is what the hard market pays for.
