Which Countries Require Boat Insurance (And Minimum Coverage Explained)

Boat insurance is one of those topics most sailors don’t think about until they absolutely have to. Often that moment comes when entering a new country, booking a marina, or signing a charter contract — and suddenly someone asks for an insurance certificate.

What surprises many cruisers is that boat insurance is not optional everywhere, and the rules are far from uniform. Some countries require it by law. Others don’t — but marinas, ports, or authorities still expect to see it. And in a few places, minimum coverage amounts are clearly defined.

This post explains how boat insurance requirements work in practice, where insurance is mandatory, and what you should realistically have in place before crossing borders.

Boat insurance laws are not global

Unlike COLREGs or radio regulations, boat insurance is regulated nationally. There is no universal rule that applies everywhere, and assumptions based on one country often don’t hold up in another.

That’s why two cruisers can have completely different experiences:

• one never being asked for insurance in years of sailing

• another being denied marina entry without proof of cover

  
  

Both can be telling the truth.

Countries where boat insurance is legally required

In several countries, liability insurance is mandatory by law, even for private pleasure boats. While details vary, the intention is the same: to ensure damage to third parties, marinas, or the environment is covered.

Common examples include:

• Italy – third-party liability insurance is mandatory

• Spain – compulsory insurance for motorboats and larger vessels

• Croatia – insurance is required for registered vessels

• Greece – mandatory third-party liability insurance

• Germany – required in many inland and coastal situations

• Netherlands – not always legally mandatory, but often required by marinas

  
  

In these countries, authorities may ask for proof during registration, port clearance, or inspections.

Minimum coverage: this is where it gets specific

Some countries don’t just require insurance — they require minimum coverage amounts, often focused on third-party liability.

Typical requirements may include:

• personal injury to third parties

• property damage (other boats, docks, marina infrastructure)

• pollution or environmental damage

  
  

For example, minimum liability limits can range from a few hundred thousand euros to several million, depending on the country and vessel size. These limits can change, so relying on old information is risky.

The important takeaway is this:

having insurance is not always enough — it needs to meet local minimums.

Countries where insurance isn’t legally required (but still expected)

In some countries, there is no explicit legal requirement for private boat insurance. However, this doesn’t mean you can sail uninsured without consequences.

In practice:

• most marinas require proof of insurance

• many ports will not accept uninsured boats

• charter companies always require it

• some authorities may still request it during checks

  
  

So even where insurance isn’t mandated by law, it is often mandatory by reality.

What about cruising between countries?

This is where many cruisers get caught out.

You may be fully compliant in your home country, but once you cross a border:

• your existing policy may not meet local minimums

• coverage territory may be limited

• documentation may not be accepted in its current form

  
  

Before entering a new country, it’s wise to check:

• whether liability insurance is mandatory

• minimum coverage limits

• whether proof must be carried on board

  
  

This “check before you go” approach is similar to other cruising rules that change by country — from connectivity restrictions to licensing requirements.

Insurance is not the only rule that changes when you cross borders — skipper licensing requirements vary just as widely, something we covered in detail in Boat License Requirements by Country.

What insurance documents should you carry?

At minimum, most cruisers should have:

• a valid insurance certificate

• clear mention of coverage territory

• stated liability limits

• vessel identification matching your registration

  
  

Digital copies are often accepted, but having a printed version on board can still save time during inspections.

Good documentation matters here, just as it does with technical upgrades and system changes. Clear paperwork avoids confusion when someone asks questions you didn’t expect.

Why this causes so much confusion online

Insurance discussions online often mix:

• legal requirements

• marina rules

• charter conditions

• personal risk tolerance

  
  

When someone says “insurance isn’t required there,” they may be legally correct — but practically wrong. When another says “you must have insurance,” they may be speaking from a marina or charter perspective.

Context matters.

The safest approach for cruisers

For most cruising sailors, the safest and least stressful approach is simple:

• carry third-party liability insurance

• make sure coverage limits are generous

• confirm your cruising area is included

• keep documents accessible

  
  

It may feel bureaucratic, but it’s far easier than dealing with denial of entry, fines, or uncovered damage.

Final thought

Boat insurance isn’t about fear — it’s about access, responsibility, and peace of mind. Rules change by country, expectations vary by marina, and enforcement can be inconsistent.

Knowing the basics before you sail lets you focus on what actually matters: the water, the weather, and the journey ahead.
