Catamarans continue to grow in popularity across Australian waters, valued for their stability, generous living space, and open-water cruising ability. Insuring a multihull involves specialist marine cover that addresses higher insured values, bridgedeck slamming exposure, and unique structural demands. Whether you own a coastal cruiser or a performance sailing catamaran, compare catamaran insurance options from Australian marine insurers below.
Club Marine is Australia's largest specialist marine insurer, backed by Allianz. Their underwriting team has deep experience with multihull vessels, offering tailored policies for cruising catamarans through to high-performance racing cats.
Catamarans have become an increasingly prominent part of the Australian recreational fleet, with owners drawn to the twin-hull design for its stability, spacious deck layout, and comfortable passages in offshore conditions. Catamaran values in Australia range from around $100,000 for older production models to well above $1.5M for new custom-built or large production vessels, making thorough insurance cover a practical necessity.
Catamaran insurance is a specialist branch of marine insurance covering both hulls, the bridgedeck structure, rigging, sails, engines (most cruising cats are power-assisted), and all installed equipment. Risks specific to multihulls include bridgedeck slamming in rough seas, the wider beam creating berthing and mooring challenges, and higher replacement costs owing to the twin-hull construction.
The Australian catamaran insurance market includes specialist marine providers like Club Marine for standard cruising catamarans, alongside general insurers such as Allianz and QBE. Given the higher average value of catamarans compared to monohulls, many owners find broker-placed specialist cover provides better terms.
Catamaran insurance is voluntary in Australia. However, most marinas require proof of third-party liability before allocating a berth, and the wider beam of a catamaran often means premium berth fees and specific mooring requirements.

Understanding what is included - and what is not - helps you assemble the right protection for your catamaran.
| Cover Type | Relevance | Why It Matters | Typical Limit |
|---|---|---|---|
| Hull & Machinery (Both Hulls) | Essential | Covers physical damage to both hulls, the bridgedeck, engines, keels or daggerboards, rudders, and permanently installed equipment. This is the foundation of any catamaran policy, responding to collision, grounding, storm damage, fire, and theft. | Agreed or market value |
| Third-Party Liability | Essential | Covers damage your catamaran causes to other vessels, moorings, marina infrastructure, or injury to third parties. Given the wider beam of a catamaran and the potential for greater contact damage in tight marina situations, adequate liability cover is critical. | $5M - $10M |
| Sails, Rigging & Spars | Essential | Covers damage to or loss of sails, standing and running rigging, mast, and boom. Catamaran rigs can be more complex than monohull setups, and high-performance sail replacement costs are significant. Ensure the sub-limit reflects current replacement prices. | Sum insured or sub-limit |
| Bridgedeck & Structural | Essential | The bridgedeck is a structural element unique to catamarans and is vulnerable to slamming forces in heavy seas. Damage can include delamination, cracking, and water ingress. Comprehensive bridgedeck repair cover is a non-negotiable element of any multihull policy. | Included in hull cover |
| Salvage & Wreck Removal | Essential | Covers the cost of recovering your catamaran after a grounding, sinking, or structural failure. Due to the size and beam of catamarans, salvage operations are more complex and costly than for monohulls, and harbour authorities may mandate removal. | Included or sub-limit |
| Charter Use Extension | Recommended | If you charter your catamaran to third parties - common in the Whitsundays and along the Queensland coast - standard recreational policies will not respond. A charter endorsement covers damage caused by charter guests and third-party liability during charter periods. | Policy extension |
| Personal Effects & Electronics | Recommended | Covers personal belongings on board along with electronics such as chartplotters, radar, autopilots, and watermakers. Cruising catamarans often carry a substantial electronics and equipment inventory. Home contents policies usually exclude items stored on vessels. | $10K - $30K |
| Extended Cruising / Bluewater | Optional | Standard policies cover Australian coastal waters. Catamarans are popular bluewater cruisers, and if you plan to sail to the Pacific Islands, South East Asia, or beyond, you will need an extended cruising endorsement or a specialist bluewater policy arranged before departure. | Policy extension |

Several variables influence how much you will pay to insure your catamaran in Australia.
Catamarans typically carry higher insured values than monohulls of similar length because of their twin-hull construction and larger living areas. The build material - fibreglass, composite, or carbon fibre - and whether the vessel is production or custom-built significantly affect premium calculations.
Catamarans require wider berths, and the limited availability of multihull berths in some Australian marinas may affect where you can moor. Sheltered marina berths attract lower premiums than exposed pile moorings. The wider beam also increases the potential for contact damage in close-quarters situations.
If you charter your catamaran commercially - especially in popular regions like the Whitsundays - your premium will be substantially higher than for private recreational use. Charter policies account for less experienced operators and increased wear. Some insurers offer combined private and charter policies.
Australian coastal waters form the standard coverage area. Catamarans are a popular choice for extended Pacific or South East Asian cruising, and cover for these voyages requires additional premium. Tropical cyclone season restrictions may apply for vessels north of the Tropic of Capricorn between November and April.
Well-maintained catamarans with current surveys, osmosis-free hulls, and documented service records may qualify for reduced premiums. Bridgedeck inspections are particularly important for multihulls. Insurers may require a marine survey for vessels beyond a certain age threshold.
A claims-free record and demonstrated multihull sailing experience can lower your premium. Recognised sailing qualifications such as Yachtmaster or Day Skipper certificates, along with specific catamaran handling experience, are valued by underwriters assessing your risk profile.
From the Whitsundays to Sydney Harbour - why catamarans are increasingly popular in Australian waters.
Catamarans have seen a steady rise in ownership across Australia over the past decade, driven by improvements in production boat building and the appeal of stable, spacious platforms for cruising and entertaining.
The Whitsunday Islands and the waters along the Great Barrier Reef are among Australia's premier catamaran cruising grounds, offering sheltered anchorages and stunning reef systems suited to the shallow draft of multihulls.
Many Australian catamaran owners embark on Pacific cruises, with popular routes running from the east coast to New Caledonia, Vanuatu, Fiji, and beyond during the favourable season.
Catamarans are a popular charter vessel in Australia, with many owners offsetting costs through bareboat or skippered charter operations, particularly in the Whitsundays and Pittwater.
Practical guidance to help you secure the right cover and potentially reduce your premium.
Agreed value policies pay a pre-determined amount if your catamaran becomes a total loss, removing the uncertainty of market valuation at claim time. Given the higher values involved with catamarans, the certainty of an agreed value policy is especially important. Market value policies risk undervaluing your vessel when you need it most.
Because of the higher insured values and specialist nature of catamaran cover, a marine insurance broker can often negotiate better terms and broader cover than direct insurers provide. Brokers can also arrange charter endorsements, bluewater extensions, and multihull-specific protections.
The bridgedeck is a structural element unique to catamarans and an area of particular interest to insurers. Regular bridgedeck inspections with photographic records can strengthen your insurance position. Any signs of delamination, cracking, or water ingress should be addressed without delay.
If you charter your catamaran - even informally to acquaintances for a fee - you must disclose this to your insurer. Undisclosed charter use can void your policy entirely. A charter endorsement adds to the premium but ensures you are protected if a claim arises during charter operations.
Maintain a detailed photographic record of your catamaran's equipment, electronics, sails, and safety gear. Include serial numbers and purchase receipts where possible. Cruising catamarans frequently carry $50,000 or more in equipment and electronics, and thorough documentation is essential when lodging a claim.
Catamarans are more susceptible to contact damage in tight marina situations because of their wider beam. Make sure your third-party liability cover is sufficient for potential marina damage. Increasing your liability limit to $10M may be prudent if berthed in a premium marina.
If you plan to cruise beyond Australian coastal waters, arrange your extended cruising endorsement well before departure. Bluewater cover for catamarans typically specifies approved routes, departure windows, and may require additional safety equipment or qualifications. Last-minute arrangements can be expensive or unavailable.
