What a boat policy typically protects
Pleasure craft policies usually cover accidental damage to the hull, machinery, rigging and equipment, theft, fire, and third-party liability. Many are written on an agreed value basis, which simplifies total loss settlements, while others pay market value. Personal effects, trailers and tenders may be covered only up to a limit.
Conditions on cruising area, lay-up periods, use for charter, racing and the skipper's experience are common. Failing to respect them can lead to a refusal, so they are among the first points the insurer's surveyor will check.
Wear, osmosis and gradual damage
Typical exclusions cover wear and tear, osmosis and blistering, marine growth, corrosion and mechanical breakdown not caused by an insured event. A sinking caused by a perished hose or a failed seacock may therefore be contested if the insurer argues it resulted from poor maintenance rather than accident.
How a leisure craft claim is surveyed
The insurer appoints a marine surveyor who inspects the vessel, ashore if possible, to establish the cause and extent of damage and to review repair estimates. Owners in the United States and Canada often meet surveyors accredited by bodies such as SAMS or NAMS; in the UK and Ireland members of the YDSA or IIMS are common. Accreditation is a useful sign of competence.
Owners should take reasonable steps to protect the boat after the incident, such as pumping out, securing or arranging lift-out, and keep receipts for these costs, which are often recoverable as salvage or mitigation expenses.
Owners are entitled to attend the insurer's survey and to ask questions. Taking notes, pointing out damage the surveyor may have missed and requesting a copy of the report afterwards all help. If the boat must be moved to a yard, ask the insurer to confirm the choice beforehand, since transport and storage can become disputed costs.
- Photographs of damage and of the mooring, anchor or trailer
- Weather reports and harbour master or marina incident records
- Purchase documents and previous condition surveys
- Engine service history and maintenance invoices
- Police report for theft or vandalism
- Boatyard estimates and lift-out invoices
Repair costs and hidden structural damage
Grounding and collision damage can extend far beyond the visible scrape. Keel bolts, internal floors, bulkheads and rudder bearings may be affected, and composite hulls may need moisture readings or core sampling. Agreeing the scope of investigation before repairs start avoids later arguments.
Engines that have been submerged need prompt inhibiting and inspection. Delays can turn a recoverable engine into a write-off, and insurers may question whether the owner acted quickly enough.
Ask the yard to break its estimate down into labour, materials and subcontracted work, and to flag any items it considers maintenance rather than accident repair. That transparency speeds up approval and limits the room for later disagreement.
Total loss and salvage
When repair costs approach or exceed the insured value, the insurer may treat the boat as a constructive total loss, pay the agreed or market value and take the wreck. Disputes centre on the realistic repair estimate, the salvage value and, where market value applies, the comparable boats used to fix it.
Storm seasons and named windstorm clauses
Owners keeping boats in hurricane-exposed waters, such as the south-eastern United States and the Caribbean, often face named storm deductibles that are higher than the standard excess, or conditions requiring a hurricane plan, haul-out or relocation before a storm. In Australia, cyclone-prone northern waters can bring similar conditions. Checking these clauses before the season starts is far easier than arguing about them afterwards.
After a storm, claims arrive in large numbers and surveyors are stretched. Owners who photograph their preparations, keep marina confirmations and record the condition of lines and fenders before the event are better placed to show they met the policy requirements. The same discipline helps in temperate waters, where autumn gales and winter lay-up ashore cause many of the claims insurers see.
Frequent sources of disagreement
Beyond wear and maintenance arguments, common disputes involve storm preparation, the adequacy of moorings, whether the boat was left unattended for too long, depreciation on sails and rigging, and the choice between repairing and replacing equipment. Breaches of navigation limits or lay-up warranties can affect the whole claim.
Owners are sometimes surprised by deductions for betterment when old sails, canvas or electronics are replaced with new ones. The policy wording decides whether such deductions apply and at what rate.
When to call in your own surveyor
For a minor claim accepted by the insurer, an independent surveyor may not be necessary. It becomes worthwhile when the damage is serious, when cover is refused on maintenance or warranty grounds, when total loss valuation is disputed or when the owner lacks the technical knowledge to challenge the insurer's report.
An owner's surveyor can review the cause, propose an alternative repair specification, examine depreciation and help assemble a coherent claim. They should be honest that a refusal based on a clear policy condition may be difficult to overturn.

Frequently asked questions
Do I need to report a minor grounding?
Yes, in most cases. Hidden damage can appear later, and late notification may give the insurer grounds to refuse cover.
Is osmosis ever covered?
Rarely. Most yacht policies exclude osmosis and blistering as gradual deterioration, though specialist policies may offer limited cover.
Can I use my own boatyard for repairs?
Usually yes, but the insurer will want to approve the estimate. Obtain written agreement before work begins.
What if my boat sinks at its mooring?
The insurer will investigate the cause, often focusing on hoses, seacocks, bilge pumps and maintenance. Preserve the failed parts and the maintenance records.
Leisure craft claims depend on prompt action, good records and an accurate technical diagnosis. An independent marine surveyor is a sound investment when the loss is large or the insurer's conclusions seem doubtful.
