Nautilus Marine Insurance returns to the Whitsundays this weekend as Hamilton Island Race Week gets under way from August 15-22, with more than 190 vessels set to compete in the 41st edition of Australia's premier offshore regatta. It's the fifth consecutive year the insurance provider has partnered with the Whitsundays regatta, and for the brokers who place cover on the fleet gathering there, the event is also a reminder of how fast the underlying risk on the water has shifted.
Chief among those shifts is lithium-ion battery risk. Portable power – from tools and torches to e-foils and aquatic toys – is now standard kit on recreational vessels, and it's changing what brokers need to understand before they place a risk. Lyndon Turner (pictured), CEO of Nautilus Marine Insurance in Australia, told Insurance Business the approach the insurance brand has taken isn't to shut the risk out, but to work with it. "So the mentality has been broad market and client education rather than trying to underwrite out or penalise clients who are managing that risk well," he said.
Turner said the danger typically isn't the boat's fixed electrical system – it's what owners bring aboard. Portable tools, aquatic toys, anything battery-powered that's portable in nature carry the highest exposure, compounded by a marine environment that batteries were never designed for. Saltwater and a corrosive onboard environment add a layer of risk to battery management that simply doesn't exist on land, and it's a distinction brokers are increasingly expected to walk clients through rather than assume they already understand.

That distinction matters for how claims play out too. Nautilus Marine Insurance's own reporting has found the frequency of lithium-ion related losses has slowed in recent years, even as the severity of any single loss has not - a pattern Turner attributed partly to regulation and government intervention catching up with the technology and partly to the education push the insurance brand has leaned on rather than blanket exclusions.
James Meggison, Nautilus Marine Insurance's national marine underwriting manager, said that standard starts well before a policy is bound.
"As part of our risk assessment, we make sure that every time a broker brings a new risk to us, they leave knowing what to look for, or what to discuss with the owner," he said. It's a discipline that turns underwriting into a two-way handover rather than a one-off form.
Where Nautilus Marine Insurance draws a firm line is on retrofits - and here brokers have something concrete to take back to clients. "Where there's a retrofit of lithium on a boat, as long as it's done by a professional, licensed, experienced electrical engineer, we're comfortable," Turner said. It's a standard brokers can put in front of a client before a policy is bound, rather than discovering after a claim that an amateur installation has complicated the outcome.
The message lands squarely for brokers across both Australian and New Zealand markets, where Nautilus Marine Insurance underwrites recreational vessels and marine business assets, from sailing dinghies through to luxury motor yachts and marina operators. It's also consistent with what marine insurers globally are grappling with: the International Union of Marine Insurance's analysis of yacht fires and lithium-ion battery hazards noted that lithium-ion fires are evidentially complex and increasingly shape underwriting and claims assessment. Pleasure craft are no exception: a recent Waitematā Harbour boat fire in Auckland underscored the limits of standard marine cover when battery-related ignition sources are involved and the Australian Maritime Safety Authority's guidance on reducing electrical fire risk points to the same portable-device charging habits Turner and Meggison flagged.
None of this is likely to slow the fleet gathering at Hamilton Island this week. But as skippers check their rigging and provisions before the starting gun, the brokers behind their cover have their own checklist - and increasingly, what's plugged in below deck is on it.
