Worth knowing
Gelderblom; cover, cost and conditions
Ten model ranges are recorded for Gelderblom, among them the Waterford 700 and 770, the Pescator 770, the Invader 800 as well as the models Family 675 and Convertible 675, with build periods between 1973 and 1998. No overall type of boat is defined in our data, and for some of the ranges we hold no individual details.
For a quote the details of the actual boat are enough: type of boat, value, year of build, propulsion or sail area and cruising range. From these the premium follows, the name of the yard does not enter the calculation. Third-party liability with a limit of indemnity of 10 to 50 million euros forms the basis of every contract.
Production of these ranges ended in the nineties. We insure regardless of year of build, place of purchase and previous owners, under full hull cover with an agreed value and with no deduction for depreciation (new for old), in the Premium tariff with no age limit. The cover applies in winter storage, during craning and launching and while in transport.
