Catamaran Insurance: What Florida Owners Need

Hull and Machinery: How Underwriters Rate a Cat

Hull and machinery (H&M) cover on a catamaran pays for physical damage to the vessel — both hulls, the bridgedeck structure, engines, generators, sails, rigging, and permanently installed equipment. The agreed value basis is standard in the US pleasure-craft market and means the insured amount is what you receive after a total loss, without depreciation arguments. Make sure your agreed value is current: catamaran values have moved sharply in recent years, and an outdated figure leaves you underinsured at the worst possible moment.

Underwriters look hard at construction material (fiberglass, carbon fiber, aluminum, or composite sandwich), year of build, the last survey date, and whether the vessel is US Coast Guard documented or state-registered. A survey no older than three to five years is typically required to bind; for older vessels or those that have changed hands recently, a clean out-of-water survey is often a condition of cover. If your cat is over a certain age or has had prior structural repairs, expect underwriters to ask for a haul-out inspection before quoting.

The Inchmaree clause — a standard extension in most H&M policies — covers damage caused by the negligence of a crew member, a defect in the machinery, or a latent defect in the hull that was not detectable at the time of the last survey. For a catamaran owner running twin diesel installations, this matters: a mechanical failure that causes secondary damage to the hull or running gear can be a significant claim, and without Inchmaree language you may find yourself arguing about whether the loss was 'accidental' or 'mechanical.' Confirm it is in your policy wording before you sign.

Named Storm Deductibles and Your Hurricane Plan

The Atlantic hurricane season runs June 1 through November 30. During that window, most policies covering Florida-based vessels apply a named storm deductible that is expressed as a percentage of the insured hull value — and it applies per named storm event, not per policy year. That deductible is materially larger than your standard deductible and can represent a significant out-of-pocket exposure on a high-value catamaran. Understand the number before you bind, not after a storm makes landfall.

Most underwriters require a written hurricane plan as a condition of cover. For a catamaran, that plan needs to be specific: where the vessel will be stored or moored during a named storm, who is responsible for executing the plan, and what the timeline is relative to a National Hurricane Center advisory. Catamarans present a particular challenge because their wide beam often means fewer haul-out options — not every yard can accommodate a 24-foot beam on a travel lift. Identify your yard in advance, confirm their capacity, and put that location in your hurricane plan. If your plan names a marina slip rather than hard standing, underwriters may apply a higher named storm deductible or restrict cover to vessels that can demonstrate a credible haul-out option.

Some policies include a lay-up credit if you remove the vessel from the water or move it to an approved inland location for part of the hurricane season. If you plan to leave the boat in the water year-round in South Florida or the Keys, discuss that explicitly with your broker — the navigation and mooring conditions during storm season are a material underwriting factor, and your policy should reflect your actual operating pattern, not an assumed one.

Navigation Limits: Florida, the Bahamas, and the Caribbean

Your policy's navigation warranty defines where your hull and liability cover is active. A standard US coastal policy may cover Florida waters and the Bahamas but exclude the Eastern Caribbean without an endorsement. If you cruise to the Turks and Caicos, the Dominican Republic, Puerto Rico, the US Virgin Islands, or further south into the Lesser Antilles, confirm that those waters are explicitly included — not just implied by a vague 'Caribbean' reference.

Gulf of Mexico cruising — from Tampa Bay west toward the Yucatan Channel or south toward Belize — is a separate navigation territory in most policy structures. If your catamaran moves between the Atlantic side and the Gulf side of Florida, your policy needs to cover both. The passage through the Florida Straits and around the Keys is routine for catamarans, but it is a geographic boundary that some policy wordings treat as a limit trigger. Ask your broker to confirm the exact boundary language in the navigation warranty.

Extended offshore passages — crossing the Gulf Stream to the Bahamas, or a blue-water passage to the Eastern Caribbean — may require prior notice to underwriters or a qualified offshore crew endorsement. For a catamaran making an offshore passage with a small crew, the qualification and experience of the skipper is a material underwriting factor. Be prepared to provide crew CVs or a captain's resume when requesting a quote or adding a new passage to your navigation area.

Protection and Indemnity: Liability Cover for Catamaran Owners

Protection and indemnity (P&I) cover pays third-party bodily injury and property damage claims arising from the operation of your vessel. For a catamaran — which has a wide beam and can cause significant damage to marina infrastructure, other vessels, or dock users — adequate P&I limits are not optional. Your marina berth agreement almost certainly requires a minimum P&I limit, and if you charter the vessel, your charter contract will specify a limit as well.

P&I also covers your legal liability for wreck removal, pollution from fuel or lubricants, and — critically — crew injury under the Jones Act if you operate with paid crew in US waters. The Jones Act creates a negligence-based liability to seamen that sits outside standard workers' compensation frameworks; a crew injury claim on a US-flagged catamaran can be substantial, and your P&I limit needs to reflect that exposure. If you operate with a paid captain or crew, discuss Jones Act exposure specifically with your broker.

The Convention on Limitation of Liability for Maritime Claims (LLMC) allows shipowners to limit their liability to a figure calculated by reference to the vessel's tonnage, expressed in Special Drawing Rights. For a pleasure catamaran, that statutory limit may be lower than the actual damages a claimant pursues — particularly in a collision or allision with a high-value vessel. Your P&I cover should sit above the LLMC limit to protect you in the event a claimant successfully argues that limitation does not apply.

Charter Use, Crew Cover, and MLC Considerations

If you charter your catamaran — whether bareboat, skippered, or crewed — your policy must include a charter use endorsement. A standard pleasure-use policy excludes commercial activity, and a single undisclosed charter trip can void your cover for an unrelated claim. Charter underwriting looks at the number of charter days per year, whether you use a professional management company, the experience level of bareboat charterers, and whether the vessel holds the appropriate USCG documentation for carrying passengers for hire.

Crewed charter operations bring crew welfare obligations into scope. The Maritime Labour Convention 2006 (MLC 2006) sets minimum standards for crew accommodation, medical care, repatriation, and compensation for injury or death. While MLC 2006 applies formally to commercial vessels over 500 GT, the welfare obligations it codifies are increasingly reflected in the crew cover that specialist underwriters expect to see on professionally crewed yachts, regardless of size. If your catamaran operates with paid crew on charter, your policy should include crew personal accident cover and repatriation costs as a minimum.

For captains holding a USCG license and operating a catamaran under a Passenger Vessel Operator (six-pack) or a larger charter license, the liability exposure is personal as well as vessel-based. Confirm that your P&I cover extends to the licensed captain's professional liability, and that the policy responds whether the vessel is under charter or on a private passage.

What to Bring When You Request a Quote

Getting a competitive quote for catamaran insurance requires more documentation than a standard monohull submission, because underwriters are pricing a vessel type with specific structural and operational characteristics. The more complete your submission, the faster and more accurately your broker can approach the specialist market on your behalf.

Prepare the following before your broker goes to market:

• Current marine survey (out-of-water preferred, no older than three to five years)
• US Coast Guard documentation number or state registration details
• Vessel specifications: LOA, beam, draft, displacement, engine make, model and hours
• Agreed value you are seeking to insure
• Navigation area you intend to cruise (Florida, Bahamas, Gulf, Eastern Caribbean — be specific)
• Hurricane plan: haul-out yard name, location, and confirmed beam capacity
• Captain and crew details: USCG license number, years of experience, offshore passage history
• Charter use: number of days per year, bareboat or crewed, management company if applicable
• Claims history for the past five years on this vessel and any prior vessel

Frequently asked questions

Do I need a separate policy for my catamaran, or can I add it to my existing monohull policy?

A catamaran is a distinct vessel type and needs its own policy. Underwriters rate it separately based on construction, beam, engine configuration, and operating area. You cannot simply endorse a catamaran onto a monohull policy — the risk profile is different enough that the policy wording, navigation limits, and named storm provisions all need to be written specifically for the cat.

What happens if I take my catamaran outside my navigation limits without notifying my underwriter?

Sailing outside your navigation warranty without prior authorization from underwriters can void your cover for any claim arising during that passage — and potentially for the entire policy period depending on the wording. If you are planning a passage to a new area, contact your broker before you leave. Most underwriters will grant a navigation extension; the key is asking in advance, not after a loss.

How does the named storm deductible work if a hurricane damages my catamaran while it's on the hard?

The named storm deductible applies to any loss caused by a named storm, regardless of whether the vessel is in the water or on the hard. It is calculated as a percentage of your agreed hull value and applies per storm event. If two named storms damage your vessel in the same season, the deductible applies twice. This is why your hurricane plan — including a confirmed haul-out location that can accommodate your beam — is so important.

Do I need Jones Act crew cover if I only use a part-time paid captain?

Yes. If you pay someone to captain or crew your vessel in US waters, they may qualify as a 'seaman' under the Jones Act, which gives them the right to sue you for negligence if they are injured. That exposure is not covered by standard P&I unless the policy specifically includes Jones Act liability. Tell your broker about any paid crew arrangement — even occasional or part-time — so the policy is structured correctly.

What do underwriters look for in a catamaran hurricane plan?

Underwriters want a specific, executable plan: the name and location of the haul-out yard, confirmation that the yard can accommodate your vessel's beam on their travel lift, the name of the person responsible for executing the plan, and a realistic timeline for getting the boat out of the water before a storm makes landfall. A plan that names a marina slip rather than hard standing will typically attract a higher named storm deductible or additional conditions.

How long does it take to bind catamaran insurance?

With a complete submission — current survey, vessel specs, navigation area, hurricane plan, and captain details — your broker can typically get indications from specialist underwriters within a few business days. Binding follows once you accept terms. If your survey is out of date or your submission is incomplete, the process takes longer. Start the renewal process at least 30 days before your current policy expires, and earlier if you are approaching the June 1 hurricane season start.
