Do I need a separate salvage endorsement, or is salvage covered under my standard hull and machinery policy?

Most specialist hull and machinery policies include salvage charges as a covered loss under the base wording, but the coverage is subject to the insured value of the vessel and the policy's general exclusions. What you need to verify is whether LOF salvage awards are explicitly covered, whether sue-and-labour costs are reimbursed in addition to the hull claim, and whether a named storm event triggers a different deductible for salvage costs. Ask your broker to pull the specific salvage and sue-and-labour language from your policy wording — not just the summary — before you cruise offshore.

What happens if I ground my catamaran outside my navigation limits?

A grounding outside your policy's navigation warranty voids the hull claim for that incident. Navigation limits are a condition of cover, not a minor technicality. If you plan to cruise beyond your current limits — into the Gulf of Mexico, down to Venezuela, or across to the Eastern Caribbean beyond your policy's stated boundary — you need a navigation limit extension agreed in writing before you depart. Extensions are available for most cruising areas, but they must be in place before the incident, not after.

My catamaran is used for bareboat charter. Does that change how a grounding claim is handled?

Yes, materially. Charter use must be disclosed at inception and at every renewal. Most underwriters apply a wider grounding deductible for charter operations, and some require a separate charter endorsement that specifies the charter area, the minimum qualifications for charterers, and the inspection regime between charters. If you have a grounding claim under a charter that was not disclosed to your underwriter, the claim is likely to be denied on non-disclosure grounds. Make sure your policy reflects your actual use.

How long does it take to bind catamaran hull cover, and what causes delays?

For a straightforward renewal with a current survey and no recent claims, binding can happen within a few business days once your broker has a complete submission. Delays occur when the survey is out of date, when there are undisclosed modifications, when the navigation area is unusual, or when the vessel has a prior grounding history that requires additional underwriter review. If you are buying cover for the first time or switching underwriters, allow at least two weeks and have your survey, documentation, and hurricane plan ready before your broker submits.

Does my hull policy cover the cost of the haulout and survey after a grounding, even if no structural damage is found?

This depends on your policy wording. Some policies cover the reasonable cost of a post-grounding inspection under the sue-and-labour clause, on the basis that inspecting for hidden damage is a step taken to prevent further loss. Others treat the haulout as a maintenance cost and exclude it unless damage is actually found. Clarify this point with your broker before a grounding happens — it is much easier to negotiate the wording at renewal than to argue it during a claim.

What is general average, and could a grounding on my catamaran trigger it?

General average is the legal principle that when an extraordinary sacrifice or expenditure is made to save a voyage — including engaging a salvor — all parties with a financial interest in that voyage share the cost proportionally. On a crewed or bareboat charter catamaran, charter guests' belongings and any cargo aboard create those additional interests. If a salvor is engaged and the cost is significant, your average adjuster may declare general average and seek contributions from all parties. Your hull policy should confirm that your underwriters will advance your own contribution during the adjustment period so you are not out of pocket while the process runs.

Catamaran Insurance: Grounding & Salvage Exclusions

Written by the Florida Yacht Cover editorial team · reviewed by Anton Kuznetsov, founder

Catamarans ground differently than monohulls, and most standard yacht policies were written with a monohull in mind. When your cat touches bottom in the Exumas, on a Bahamian bank, or on a Gulf coast shoal, the claim that follows can expose gaps in your hull and machinery cover that you never knew existed. Salvage costs alone can exceed the value of a lightly insured vessel. Before you renew — or buy for the first time — you need to understand exactly which grounding and salvage scenarios your policy covers, which it excludes, and what your broker should be negotiating on your behalf.

Why Catamarans Face Unique Grounding Exposure

A catamaran's wide beam and shallow draft make it the preferred platform for Bahamian cruising, but those same characteristics increase grounding frequency. The Bahamas Bank, the Turks and Caicos, and the shallow anchorages of the Florida Keys all carry charted depths that can shift after storms. A monohull that touches bottom often pivots off under sail or engine power. A cat can settle firmly on both hulls simultaneously, making self-recovery impossible and professional salvage unavoidable.

Your hull and machinery policy responds to sudden and accidental physical damage. Grounding is a named peril under most policies, but the word 'accidental' carries more weight than owners typically realize. Underwriters will scrutinize the circumstances: Was the chart datum current? Did you have a functioning depth sounder? Were you navigating at night in an area your policy's navigation limits actually cover? Any of these factors can shift a covered grounding toward a disputed or excluded claim.

The structural consequence of a catamaran grounding is also more complex. Stress fractures in the bridgedeck, delamination in the hulls, and damage to the crossbeam structure may not be visible on the surface. Underwriters frequently require a full haulout and survey before agreeing a settlement figure, and the cost of that survey — plus the haulout itself — is often not covered unless your policy includes sue-and-labour provisions that extend to investigative costs.

Salvage Costs: What Your Policy Actually Pays

Salvage is one of the most expensive single-incident costs a catamaran owner can face. A professional salvage operation in the Bahamas or the Caribbean — involving a tug, a crane barge, and a dive team — can run to sums that dwarf the deductible and, in some cases, approach the insured value of the vessel. Your policy's response depends on how salvage is defined and whether your hull and machinery section includes a separate salvage clause or folds it into the general collision and damage provisions.

Under the Institute Hull Clauses framework that most specialist underwriters use as a base, salvage charges are a covered loss — but only up to the insured value of the vessel, and only when the salvage operation is undertaken to preserve an insured interest. If your catamaran is on a reef and the salvage contractor presents a Lloyd's Open Form (LOF) contract, the 'no cure, no pay' structure means the award is determined by arbitration and can be substantial. Your policy should explicitly confirm that LOF salvage awards are covered under your hull section, not just your protection and indemnity (P&I) section.

The sue-and-labour clause is your most important tool in a grounding scenario. It obliges you to take reasonable steps to prevent further loss, and it obliges your underwriters to reimburse those costs even if the vessel is ultimately a total loss. In practice, this means the cost of emergency pumping, temporary patching, and engaging a salvor to prevent a grounded cat from breaking up in surf can be recovered separately from — and in addition to — the hull claim itself. Make sure your policy does not cap sue-and-labour reimbursement at a figure that makes emergency response uneconomical.

Common Exclusions That Catch Catamaran Owners Off Guard

Not every grounding is treated equally by underwriters. The following exclusions appear with enough frequency in catamaran policies that you should verify each one before binding cover.

Wear, tear, and gradual deterioration exclusions are standard, but underwriters sometimes apply them aggressively to osmotic blistering or delamination discovered after a grounding. If your surveyor's report mentions pre-existing hull condition issues, the underwriter may apportion the claim — paying only for damage directly attributable to the grounding event and excluding anything they classify as pre-existing deterioration.

Navigation limit exclusions are particularly relevant for Florida-based catamaran owners. Most policies define a cruising area — commonly the US East Coast, the Bahamas, and the Caribbean to a specified latitude. Grounding outside those limits voids the hull claim entirely. If you plan to cruise the Gulf of Mexico, the Yucatan Channel, or beyond the standard Caribbean waypoints, confirm that your navigation warranty covers the intended route before you leave the dock.

Crew negligence and operator error are often excluded or subject to a higher deductible when the vessel is under charter. If you operate your catamaran as a bareboat or crewed charter, your policy structure changes materially. Charter use typically requires an endorsement, and some underwriters impose a separate grounding deductible for charter operations that is significantly wider than the standard hull deductible.

Grounding caused by failure to maintain a proper watch — may be treated as operator negligence rather than an accidental peril
Damage to running gear (props, shafts, rudders) from grounding — sometimes excluded or subject to a separate machinery deductible
Consequential damage from delayed salvage — if you wait to engage a salvor and the vessel sustains additional damage, that incremental loss may be excluded
Pollution liability arising from a grounding — typically falls under P&I, not hull and machinery; confirm your P&I section covers fuel spill response costs
Grounding in areas designated as marine protected zones — some policies exclude claims arising from navigation in restricted areas

Named Storm Deductibles and Hurricane Season Planning

Florida-based catamaran owners face a named storm deductible that operates separately from the standard hull deductible. The Atlantic hurricane season runs June 1 through November 30, and most policies require you to have a documented hurricane plan in place before June 1. That plan typically specifies where the vessel will be laid up or stored, whether it will be hauled, and who is responsible for executing the plan if you are not aboard.

A catamaran presents specific challenges for hurricane planning. Its wide beam means fewer boatyards can accommodate it on the hard, and the cost of a suitable cradle or jackstand arrangement is higher than for a comparable monohull. If your hurricane plan specifies a yard that cannot actually haul your vessel's beam, your underwriter may treat the plan as non-compliant and apply the named storm deductible even if the vessel was moved in good faith.

Grounding during a named storm event is treated differently from a routine grounding. The named storm deductible applies to all physical damage arising from the storm, including grounding, and it is typically expressed as a percentage of the insured value rather than a fixed dollar amount. This means that on a high-value catamaran, the named storm deductible can be a very significant sum. Confirm with your broker whether your salvage costs in a named storm scenario are subject to the named storm deductible or the standard hull deductible — the answer varies by underwriter and policy wording.

What to Bring to Your Broker Before Binding or Renewing

Underwriters price catamaran hull cover based on the vessel's construction, age, survey condition, cruising area, and your experience as an owner or captain. A current out-of-water survey — typically required every three to five years and always after a grounding — is the single most important document in your file. If your survey is approaching its expiry date, renew it before your policy renewal date, not after. A lapsed survey gives underwriters grounds to dispute claims on condition grounds.

Your US Coast Guard documentation or state boat registration, your captain's license or documented offshore experience, and your hurricane plan are all standard submission requirements. For a catamaran specifically, underwriters will also want to know the construction material (fiberglass, carbon fiber, aluminum), the bridgedeck clearance, and whether the vessel has been modified from its original specification. Non-standard modifications — extended crossbeams, added watermakers, generator installations — should be disclosed; undisclosed modifications can void cover.

If you operate under charter, bring your charter management agreement, your bareboat or crewed charter endorsement from your current policy (if you have one), and your crew list with US Coast Guard license numbers. Charter use is a material fact that must be disclosed at inception and at every renewal. Failing to disclose it is the fastest way to find yourself without cover at the moment of a grounding claim.

How General Average and Salvage Interact on a Catamaran

General average is the principle — codified under the York-Antwerp Rules — that when a sacrifice is made or an extraordinary expenditure is incurred to save a voyage, all parties with a financial interest in that voyage contribute proportionally to the loss. On a catamaran carrying personal property, charter guests' belongings, or cargo, a grounding that requires a salvage operation can trigger a general average declaration. Your hull underwriters will appoint an average adjuster, and the process can take months to resolve.

What many catamaran owners do not realize is that general average contributions from other parties — charter guests, for example — are not automatic. If a guest refuses to contribute, or if their travel insurance does not cover general average, you may find yourself advancing their share while the adjustment is pending. Your hull policy should include a general average absorption clause or, at minimum, confirm that your underwriters will advance your own contribution while the adjustment is ongoing.

The interaction between salvage costs and general average is particularly complex when the salvor presents an LOF contract. The salvage award, once arbitrated, is then apportioned under general average rules. Your broker should confirm that your hull and machinery policy responds to both the salvage award and your general average contribution without requiring you to fund either out of pocket while the claim is being adjusted.
