Worth knowing
Derenthal; cover, cost and conditions
One motor yacht is recorded for the Derenthal brand, the Sea Horse with a production period from 1965 to 1976. With boats that are looked after and upgraded over decades, part of the value lies in the equipment. Therefore include electronics, navigation and permanently installed technology in the list.
The agreed value that is settled reflects the value together with the equipment. In the event of a claim we pay with no deduction for depreciation (new for old), in the Premium tariff with no age limit. The full hull cover additionally covers collision, grounding, vandalism and theft of parts including the outboard.
The limited hull cover takes on fire, storm, lightning strike, theft of the entire boat and damage in winter storage. Third-party liability with a limit of indemnity of 10 to 50 million euros remains the basis. Up to a sum insured of 2.5 million euros you can conclude the contract online.
