Worth knowing
Stjärn-Plast; cover, cost and conditions
One model range is documented, the Havsrockan, built as a motorboat between 1970 and 1978. A small product programme or a boat from a small series is no obstacle: NAMMERT insures small series and home-built boats just as it does boats from large model ranges.
For the premium, the type of boat, the value, the year of construction, the engine power and the cruising range count, not the number of units and not the name of the shipyard. Full hull cover calculates with an agreed value and indemnifies with no deduction for depreciation ("new for old"), in the Premium tariff with no age limit.
On a boat from the nineteen-seventies the schedule is important: equipment and permanently installed electronics belong in it so that the agreed sum holds. Beyond that, the cover applies in winter storage, during craning, during launching and on transport.
