Boat insurance for older, timber or modified boats

An older or unusual boat is not automatically uninsurable.

But it may not fit the same online quote process as a newer standard production boat.

Insurers can ask more questions about:

• age
• construction
• condition
• repairs
• rigging
• machinery
• modifications
• value
• storage
• cruising plans

Some providers also specialise in boats that fall outside normal mainstream underwriting.

How old is too old for boat insurance?

There is no universal age.

Different providers use different rules.

One insurer may accept a boat subject to a survey while another may refer or decline it.

Youi provides a clear current example. Its April 2026 Watercraft Target Market Determination says its product is not suitable for watercraft manufactured before 1970.

That does not mean pre-1970 boats cannot be insured.

It means that particular product is not designed for them.

Pantaenius provides a different example. Its current Australian target-market documents separate newer and older production and one-off boats into different products.

The useful question is therefore not:

Is my boat too old to insure?

It is:

Which providers are prepared to consider a boat of this age and condition?

Why can older boats need more individual underwriting?

Age by itself does not tell an insurer what condition a boat is in.

Two boats built in the same year can be very different.

One may have:

• recent engines
• updated rigging
• a documented refit
• good maintenance records
• a recent survey

The other may have had little maintenance for years.

That is why an insurer can ask for more information before deciding whether to offer cover.

What about timber or wooden boats?

Timber boats can be insured, but they may need more individual assessment.

An insurer may want information about:

• hull condition
• maintenance
• previous repairs
• moisture or rot
• fastenings
• structural work
• age of the boat
• survey history

Do not assume every insurer treats timber construction the same way.

Some specialist marine providers actively consider older and timber boats.

Others may have tighter rules.

What about steel, ferrocement or unusual construction?

Less common hull materials can also lead to more questions.

The public policy information available does not support one simple market-wide rule for every material.

If your boat has an unusual construction, tell the provider exactly what it is rather than selecting the nearest standard option on an online form.

A specialist broker or marine underwriter may be more useful if the normal quote form does not describe the boat properly.

What counts as a modification?

A modification is not just a cosmetic change.

Things that can matter include:

• replacing an inboard engine
• increasing engine power
• changing performance
• major hull alterations
• changing hull length
• structural work
• major refits
• lithium battery systems
• custom electrical systems
• non-standard equipment
• substantial restoration work

Some policies require certain changes to be disclosed or agreed before cover applies.

Do you need to tell the insurer about a new engine?

Yes, where the change is material or the policy requires disclosure.

A repower can change:

• the boat's value
• power
• top speed
• weight
• handling
• mechanical risk

QBE's current pleasure craft wording provides one example where specified major repairs or alterations require prior written agreement, including certain engine and hull changes.

Do not assume a new engine is automatically covered because the old one was.

What about restoration and refits?

Tell the insurer about significant work.

A refit can improve a boat dramatically, but it does not automatically increase the insured value by the total amount spent.

If you have spent $80,000 restoring a boat, the insurer may still want evidence of its current value.

Keep:

• invoices
• photographs
• specifications
• survey reports
• valuation reports

These can help show what has actually changed.

Survey, valuation and condition report: what is the difference?

They are not the same document.

Marine survey

A survey generally looks at the condition of the boat and may identify defects or areas that need attention.

Valuation

A valuation focuses on the value of the boat.

Condition report

This may be a more limited assessment requested by an insurer to help with underwriting.

The terminology and requirements vary between providers.

Ask exactly what document the insurer wants before paying for one.

Club Marine's current wording, for example, allows it to ask for things such as a condition report, survey, rigging report, photographs or valuation at the owner's cost.

Does every older boat need a survey?

No.

There is no market-wide rule that every boat over a certain age must have one.

Some insurers may ask for a survey based on:

• age
• construction
• value
• condition
• mooring
• intended use

Others may not.

Do not pay for a survey purely because the boat is old unless you need one for another reason or a provider has told you what it requires.

Build an underwriting pack

If your boat is older, timber, custom-built or heavily modified, having the information ready can make the process easier.

Useful documents can include:

• recent photographs
• make, model and build year
• builder details
• hull construction
• purchase details
• maintenance records
• service history
• repair invoices
• refit invoices
• engine details
• rigging details
• modification specifications
• previous surveys
• valuations
• intended storage or mooring
• intended cruising area

You may not need all of this.

But it is easier to answer underwriting questions if the information is already together.

What about wear, rot and corrosion?

Insurance is not generally designed to pay for ordinary maintenance.

Boat policies commonly contain exclusions or restrictions relating to things such as:

• wear
• deterioration
• corrosion
• rot
• lack of maintenance
• unseaworthiness

The exact wording differs between policies.

This is another reason condition and maintenance records can matter for older boats.

What if an online insurer will not give me a quote?

An online decline does not necessarily mean the boat cannot be insured.

Standard online quote systems are often designed around more common risks.

An unusual boat may need:

• manual underwriting
• more documents
• a specialist insurer
• an underwriting agency
• a marine broker

If the form does not let you properly describe the boat, do not change the answers just to get through it.

Look for a provider that is prepared to assess the actual risk.

What should you check before buying an older boat?

If insurance will matter to the purchase, it is worth doing some homework before settlement.

Check:

• whether insurers will consider the age
• whether the construction is acceptable
• whether a survey will be needed
• whether old rigging or machinery creates issues
• whether modifications have been documented
• whether you can support the proposed insured value
• whether your intended cruising area is acceptable

Finding out after buying the boat can leave you with fewer options than expected.

What about agreed value?

Valuation can be particularly important for an older, restored or custom boat.

There may be fewer comparable boats available to establish value.

If agreed value matters to you, ask what evidence the provider will accept.

Our guide to agreed value vs market value for boat insurance explains how the two approaches work.
