Good to know

On an electric boat the battery is the policy

A large part of the value of an electric boat sits in cells and power electronics, and that is precisely the part a wording written for petrol engines never mentions. What follows is not a surcharge, it is a different sentence in the conditions.

Is the battery covered on an electric boat?

In short

Yes, once the boat is declared as electric, the electric boat clause applies in every tariff. On top of the named perils it pays consequential damage from animal bite or short circuit (up to 10,000 euros in Basis, 20,000 from Basis-Plus), clean up and disposal after battery damage (1,500, 10,000 or 3,000 euros in Basis, Basis-Plus, Premium) and your own charging station (1,500 or 3,000 euros). Liability starts at 49 euros a year.

Six points a petrol wording misses

None of them is exotic. All of them are ordinary on an electric boat.

Cells in every tariff

The electric boat clause is part of all three tariffs once the boat is declared as electric. The battery is insured with the boat from the first day.

Charging equipment ashore

The charger aboard belongs to the boat, and your own charging station is insured up to 1,500 euros in Basis and 3,000 from Basis-Plus.

Animal bite

Animal bite as such is excluded, but the consequential damage after a bite is paid, up to 10,000 euros in Basis and 20,000 from Basis-Plus.

Disposal after a fire

A damaged battery has to be cleared and disposed of as hazardous waste. That cost is inside the cover, up to 1,500 euros in Basis, 10,000 in Basis-Plus and 3,000 in Premium.

Short circuit and electronics

Consequential damage to controller and drive is covered up to 10,000 euros in Basis and 20,000 from Basis-Plus. The component that shorted itself is not.

Sum insured with the battery

The sum insured includes the battery, so a total loss does not settle on the value of an empty hull.

Where the value really sits

Plainly said

On a ten metre electric launch, the pack can be a third of the purchase price and it ages on its own schedule. Insure the boat and forget the pack, and the sum insured is wrong before the first season is over.

Tell us the capacity in kilowatt hours and the year the pack was fitted. If it was replaced later, that raises the agreed value rather than complicating the claim.

What we need for a quote

Before you buy

Length, motor output, battery capacity and year, value including the pack, and where the boat is charged and stored.

The three questions you actually have

Before you sign

Not “what does it cost” for your electric boat; you can work that out yourself in a minute. These are the three nobody asks an insurer out loud. Here they are, with the answers we can back up.

“Will they actually pay?”

As your broker we handle the claim with you, your electric boat included: one report to us, then we arrange the surveyor and one of more than 2,000 partner yards and follow it through to payment. The yard invoices directly; you pay the deductible and nothing else.

What happens in the first 48 hours →

“Who picks up the phone?”

A family firm since 1989, now in its second generation, with three of its own offices: Königs Wusterhausen near Berlin, Salzburg and Palma de Mallorca. No call centre, no franchise. You get a named contact for your electric boat from the first hour; and after office hours, a number somebody answers.

Which language is the policy wording in?

The policy wording is German; we go through it with you in English Our terms and conditions, the insurance product information documents and the cancellation notice exist in German, and the German wording is the binding one. We will not pretend otherwise. What we do: send you the product information documents translated, and walk you through the cover for your electric boat on the phone in English before you sign anything. The full cover for your electric boat, clause by clause, is written out in English on our detail page. Ask us for the documents and we send them the same working day. Any translation we provide is a courtesy translation; in case of doubt the German version prevails. Read the cover in full Request the documents

Frequently asked

Questions and answers

Is the battery covered on an electric boat?

Yes, once the boat is declared as electric, the electric boat clause applies in every tariff.

On top of the named perils it pays consequential damage from animal bite or short circuit (up to

10,000 euros in Basis, 20,000 from Basis-Plus), clean up and disposal after battery damage (1,500,

10,000 or 3,000 euros in Basis, Basis-Plus,

Premium) and your own charging station (1,500 or 3,000 euros).

Liability starts at 49 euros a year.

Is the charging equipment covered?

The charger on board belongs to the boat and is included.

Your own charging station is insured up to 1,500 euros in Basis and 3,000 euros from Basis-Plus;

the charging point on the pontoon belongs to the marina.

If your cable causes damage to someone else's property, that is a liability matter,

and a crushed cable is one of the more common causes.

Does the policy replace a battery that has lost capacity?

No.

Capacity loss over the years is ageing and is not covered under any hull policy.

What is covered are the named events of your tariff, such as fire, storm and theft,

from Basis-Plus also accidents.

Then the battery counts as part of the sum insured.

How much is the premium for an electric boat per year?

Liability for an electric boat starts at 49 euros a year.

Hull cover is rated on the sum insured,

and battery and charger count towards the value of the boat.

Partial cover starts at 199 euros, full cover at 219 euros a year;

only the quote with your figures is binding.

How high is the deductible for an electric boat?

For hull cover on an electric boat you agree 500 or 1,000 euros, nothing more;

there are no hidden extra deductions and no scales by type of loss.

In Basis PLUS and Premium the deductible does not apply to total loss and theft,

in Premium for theft only if the craft was kept locked away or on enclosed premises.

After five claim-free years it is halved there for the first claim;

in Basis the agreed amount always applies.

Are my own handling errors covered on an electric boat?

With full cover, yes: grounding, collision and handling errors with an electric boat are claims.

Even in cases of gross negligence the insurer waives its defence,

up to 25 percent of the sum insured in Basis PLUS and up to 50 percent in Premium, unless theft,

alcohol or drugs caused the loss.

Only intent is always excluded, and partial cover does not carry your own errors.

Are storm, theft and vandalism covered on an electric boat?

Storm, fire, lightning and theft of the whole electric boat are covered already under partial

cover.

Sinking, theft of parts including the outboard and vandalism come with full cover from Basis-Plus.

This applies in winter storage and on the trailer as well, except under a seasonal policy.

Salvage is paid on top when the authority orders it: up to the sum insured in Basis,

up to 1 million euros in Basis-Plus and up to 2.5 million in Premium.

New value or current value: what is paid for an electric boat on a total loss?

In Premium the agreed value, the amount you and the insurer fixed when the policy started,

with no deduction for the age of the electric boat and no argument after the loss.

In Basis-Plus the same applies up to five years of age,

or later while the current value still reaches half the sum insured, once replacement is shown;

otherwise the current value is paid.

In Basis, the partial cover, the current value is paid,

meaning what the electric boat was worth immediately before the loss,

less a scaled age deduction after three years.

Does the cover apply to an electric boat abroad?

Yes, within the cruising area stated in the policy and on the way there on the trailer or roof

rack.

For an electric boat that is usually Europe including the Mediterranean, worldwide on request.

Premium covers six weeks a year outside the agreed area, the other tariffs only by prior agreement.

Italy, Spain, Croatia (from 15 kW), Greece,

Denmark and Swiss waters require liability cover by law.

Is insurance for an electric boat required by law?

Not in Germany, with one exception:

on the Swiss part of Lake Constance liability cover is compulsory, as on all Swiss waters.

Italy, Spain, Croatia from 15 kW, Greece and Denmark require it too.

Regardless of the law, most marinas,

clubs and winter storage yards ask for proof before they let you a berth for the electric boat.
