Grady-White Marlin 300: cover, cost and conditions

Grady-White Marlin 300: for the premium the model name is not the deciding figure. What counts is the type of boat, its year, its value, its engine output and the waters you sail, the five entries you make in the online calculator.

For the Grady-White Marlin 300: On a fishing boat the gear is the underestimated value: sonar, bow motor, batteries and rod holders add up to more than the hull. Fitted equipment is included in hull cover when it is part of the sum insured.

What does cover for a Grady-White Marlin 300 cost? The premium starts from €39 a year for a sailing boat, from €49 for a motorboat.

On a total loss we pay the agreed value, and in the Premium tariff with no deduction for new-for-old.

Bought used, imported or ordered new: we write the Grady-White Marlin 300 with a berth in Germany and abroad alike.
