Worth knowing

Custom Boat; cover, cost and conditions

Under Custom Boat, 52 model ranges are recorded, among them the Advantage models 20.5 Classic, 21 SR, 22 Citation, 22 Sport Cat and 25 Citation. The build periods begin in 2002 and run to the present day. The type of boat is not defined in the records, which is why the details of the individual boat count for the policy.

Small series and home builds can be insured. We insure regardless of year of construction, place of purchase and previous owners, and even then full hull cover works with a firmly agreed value. Compensation is paid with no deduction for depreciation (new for old), in the Premium tariff with no age limit and with no subsequent deduction for current market value.

What counts for the rating is the type of boat, value, year of construction, engine output or sail area, and cruising range, never the brand. Up to a sum insured of 2.5 million euros the policy can be taken out online; above that we review each case individually. Third-party liability with a limit of indemnity of 10 to 50 million euros forms the basis.

Questions and answers

Frequent questions

How is a boat rated when its type of boat is not defined?

For Custom Boat: We start from the details of your boat: type of boat, value,

year of construction, propulsion and cruising range.

The rating follows from these, regardless of the manufacturer designation.

Can a one-off be insured?

Yes, for Custom Boat too: Small series and home builds can be insured.

You tell us the value and the equipment,

and from this the agreed value for full hull cover is formed.

Third-party liability

Hull cover

For the whole class of boat

Insuring a Custom Boat: what matters depends less on the brand than on engine output,

how a claim is settled and the waters you sail.

What this means for the cover

As the Advantage 20.5 Classic, Advantage 20.5 Classic BR,

Advantage 21 SR by Custom Boat and 41 more series are still in production,

parts are available and repair costs are predictable.

Even so, value it at replacement cost including retrofitted electronics, not at list price.

For the Advantage 22 Citation, Advantage 22 Party Cat,

Advantage Poker Run 40 by Custom Boat and 5 more series the market value and the replacement cost

often differ widely.

An agreed value removes the age-based scale, and the figure in the policy stands.

For the Advantage 20.5 Classic, Advantage 20.5 Classic BR,

Advantage 21 SR by Custom Boat and further series:

On a motorboat the drive is the single most valuable part.

Damage after grounding is covered, an engine failure from wear is not.

For the Advantage 25 Citation, Advantage 25 Citation BR,

Advantage 26 Party Cat LX by Custom Boat and further series:

On motor yachts the drive and the electronics together make up about half the value.

Both belong in the valuation, otherwise the sum insured is too low.
