Catamarans are growing in popularity across New Zealand, prized for their stability, space, and bluewater capability. Insuring a multihull requires specialist marine cover that accounts for higher insured values, bridgedeck slamming risks, and unique structural considerations. Whether you own a coastal cruising cat or a performance sailing catamaran, compare catamaran insurance options from NZ marine insurers below.
Tower is one of NZ's leading boat insurers, offering flexible cover for catamarans and multihull vessels. Known for straightforward policies and competitive pricing for both cruising and performance catamarans.
Catamarans have become increasingly popular in New Zealand waters, with more owners choosing multihulls for their stability, spacious living areas, and excellent bluewater cruising performance. Catamaran values in NZ range from $80,000 for older models to well over $1M for new production or custom-built vessels, making proper insurance essential.
Catamaran insurance is a specialist form of marine insurance that covers both hulls, the bridgedeck structure, rigging, sails, engines (most cruising cats are powered), and all equipment on board. Multihull-specific risks include bridgedeck slamming in heavy seas, the wider beam creating unique berthing and mooring challenges, and the potential for capsize in extreme conditions - though modern designs have largely mitigated this risk.
The NZ catamaran insurance market includes mainstream insurers like Tower for standard cruising cats, and specialist marine underwriters accessed through brokers for higher-value or charter vessels. Due to the higher average value of catamarans compared to monohulls, many owners benefit from broker-arranged specialist cover.
All catamaran insurance in NZ is optional - there is no legal requirement. However, most marinas require evidence of third-party liability insurance before granting a berth, and the wider beam of catamarans often means premium berth fees and specific berthing requirements.

Understanding what's included - and what's not - helps you build the right cover package 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/daggerboards, rudders, and permanently installed equipment. This is the core of any catamaran policy and covers 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. Essential given the wider beam of catamarans and the potential for greater damage in close-quarters marina situations. | $2M - $5M |
| Sails, Rigging & Spars | Essential | Covers damage to or loss of sails, standing rigging, running rigging, mast, and boom. Catamaran rigs are often more complex than monohull rigs, and replacement costs for high-performance sails can be significant. | Sum insured or sub-limit |
| Bridgedeck & Structural | Essential | The bridgedeck is a critical structural element unique to catamarans. Bridgedeck slamming in heavy seas can cause structural damage, delamination, or cracking. Cover for bridgedeck repair is essential for any multihull policy. | Included in hull cover |
| Salvage & Wreck Removal | Essential | Covers the cost of salvaging your catamaran after a grounding, sinking, or structural failure. Due to the size and beam of catamarans, salvage operations can be more complex and costly than for monohulls. | Included or sub-limit |
| Charter Use Extension | Recommended | If you charter your catamaran to third parties, standard recreational policies will not cover commercial use. 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 and electronics (chartplotters, radar, autopilots, watermakers). Cruising catamarans often carry significant electronics and equipment. Standard home contents insurance usually excludes items stored on vessels. | $10K - $30K |
| Extended Cruising / Bluewater | Optional | Standard policies cover NZ coastal waters. Catamarans are popular bluewater cruisers - if you plan to cruise to the Pacific Islands, Australia, or beyond, you need an extended cruising endorsement or a specialist bluewater policy. | Policy extension |

Several factors influence how much you'll pay to insure your catamaran in New Zealand.
Catamarans generally carry higher insured values than equivalent-length monohulls due to their twin hulls and larger living spaces. Construction material (fibreglass, composite, carbon fibre) and build quality (production vs custom) significantly affect premiums. Newer production cats from established builders may attract lower premiums than older or custom vessels.
Catamarans require wider berths, and marina berth availability can affect where you moor. Sheltered marina berths attract lower premiums than exposed moorings. The wider beam also means more potential for contact damage in tight marina situations.
If you charter your catamaran commercially, your premium will be significantly higher than for private recreational use. Charter policies cover damage caused by less experienced operators and increased wear and tear. Some insurers offer combined private/charter policies.
NZ coastal waters are the standard coverage area. Catamarans are popular for extended Pacific cruising - cover for Fiji, Tonga, and beyond requires additional premium. Tropical cyclone season restrictions may apply for vessels in the Pacific between November and April.
Well-maintained catamarans with current surveys, osmosis-free hulls, and documented service history may qualify for lower premiums. Bridgedeck inspections are particularly important for multihulls. Insurers may require a marine survey for vessels over a certain age.
A clean claims history and multihull sailing experience can reduce your premium. Recognised sailing qualifications (Yachtmaster, Day Skipper) and specific catamaran experience are valued by underwriters. Multiple claims or limited experience may result in higher excess amounts.
From coastal cruising to Pacific passages - why catamarans are increasingly popular in NZ waters.
Catamarans have surged in popularity across New Zealand over the past decade, driven by advances in production boat building and the appeal of stable, spacious cruising platforms.
The Hauraki Gulf and Bay of Islands are prime catamaran cruising grounds, offering sheltered waters and numerous anchorages suited to the shallow draft of multihulls.
Many NZ catamaran owners cruise to the Pacific Islands, with the "coconut milk run" from NZ to Fiji, Tonga, and beyond being one of the world's classic cruising routes.
Catamarans are popular charter vessels in NZ, with some owners offsetting ownership costs through bareboat or skippered charter operations.
Practical tips to help you get the right cover and potentially reduce your premium.
Agreed value policies pay a fixed amount if your catamaran is a total loss, regardless of market fluctuations. Given the higher values involved with catamarans, the certainty of an agreed value policy is particularly important. Market value policies may undervalue your vessel at the time of a claim.
Due to the higher insured values and specialist nature of catamaran cover, a marine insurance broker can often access better terms and wider cover than direct insurers. Brokers can also arrange charter endorsements, bluewater extensions, and multi-hull-specific cover.
The bridgedeck is a unique structural element of catamarans and a potential area of concern for insurers. Regular bridgedeck inspections and documentation of condition can strengthen your insurance position. Any signs of delamination, cracking, or water ingress should be addressed promptly.
If you charter your catamaran - even occasionally to friends or family for a fee - you must declare this to your insurer. Undisclosed charter use can void your policy entirely. A charter endorsement costs more but protects you from a declined claim.
Maintain a detailed photographic inventory of your catamaran's equipment, electronics, sails, and safety gear. Include serial numbers and purchase receipts where possible. Cruising catamarans often carry $50,000+ in equipment and electronics - documentation is essential for claims.
Catamarans are more vulnerable to contact damage in tight marina situations due to their wider beam. Ensure your third-party liability cover is adequate for potential marina damage. Consider increasing your liability limit to $5M if berthed in a premium marina.
If you plan to cruise beyond NZ coastal waters, arrange your extended cruising endorsement well before departure. Bluewater cover for catamarans typically specifies approved routes, date windows, and may require additional safety equipment or qualifications. Last-minute arrangements can be costly or unavailable.
