After five consecutive years of double-digit increases, the hull and machinery (H&M) market for yachts is quietly turning in 2026. First-half renewals are coming out broadly flat to minus 5 percent, fresh capacity from new Lloyd’s syndicates and US carriers such as Falvey, Arch and AXIS Specialty is returning to the market, and brokers are once again — cautiously — describing the environment as buyer-friendly. For mega-yacht managers, it is tempting to read this as an open window. The reality is more nuanced: above 40 metres, the market remains highly selective, and three underlying dynamics — catastrophic losses, lithium-ion fire risk and renewed pressure on P&I — could just as quickly close it again.
Five years of hikes, a first reversal
Since 2018, marine insurance had been on a continuous upward path, driven by deteriorating loss ratios, the exit of historic capacity and a hardening reinsurance backdrop. On the yacht H&M side, renewals had been running at roughly plus 10 percent a year, with tightened exclusions and higher deductibles. In 2026, several carriers consider the corrective phase complete: capacity is coming back and competition is reawakening. In practice, a clean mega-yacht — no claims over three years, stable crew, documented maintenance programme — can now expect a flat renewal, or even a small reduction, on terms that would have been unthinkable eighteen months ago.
That softening, however, is uneven. Yachts above 50 metres find fewer willing markets than 30–40 metre units: only a handful of Lloyd’s syndicates are still prepared to write insured values above €80 M, and all apply rigorous underwriting — condition surveys, captain qualifications, detailed cruising plans. The “soft market” trumpeted in the trade press applies first and foremost to commercial fleets and industrial risks; mega-yacht owners continue to operate in a narrower sub-market, where pricing remains tightly coupled to each vessel’s individual track record.
Lithium-ion, climate, mega-claims: what pushes underwriters back
Three signals contradict the easing narrative. The first is lithium-ion battery risk: foils, e-foils, electric jet-skis, sea-bobs and auxiliary battery systems have proliferated on board, often stored in technical garages without dedicated detection. Several marina fires in 2025 were directly traced to such batteries, and underwriting has tightened accordingly: mandatory battery inventory disclosure, fire-rated storage requirements and, in some cases, dedicated sub-limits.
The second signal is climatic. The 2025 Mediterranean season was marked by violent storm events on the French Riviera, in Sardinia and the Balearics — at dates well outside the traditional cyclone window. Underwriters now build “off-season” scenarios into pricing and contractual safe-haven clauses are becoming more common, including mandatory distances from alert zones and reinforced moorings.
The third signal comes from P&I. The two large pool claims — the container ship Dali and the X-Press Pearl — are expected to generate more than one billion dollars in mutualised losses, keeping general increases in the high single digits despite the strong financial position of several clubs. For commercial mega-yachts that rely on international club P&I cover, 2026/2027 renewal terms may prove less favourable than what H&M is offering.
Preparing the renewal: where the difference is made
In a two-speed market, the ship manager becomes a central player in underwriting. Submission quality weighs more than ever on the final premium. Three elements now draw most underwriter scrutiny: maintenance traceability (up-to-date PMS, class reports, engine and propulsion overhaul records), crew governance (captain turnover, STCW certifications, MLC compliance) and lithium-ion risk control — now treated as a standalone underwriting topic. A structured submission, fed in real time by data from the vessel, often turns a defensive renewal into a constructive negotiation.
The 2026 market is neither hard nor soft: it is selective. Owners who invest in documenting their risk capture the upside of the easing. Those who do not stay anchored in the plus 10 percent zone.
