Excess 11: cover, cost and conditions
Excess 11: 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 Excess 11: On a catamaran the bridgedeck between the hulls is the sensitive part, and the berth belongs in the application: double the beam often means a mooring rather than a marina berth.
What does cover for a Excess 11 cost? The premium starts from €39 a year for a sailing boat, from €49 for a motorboat. Hull cover follows the value: partial cover answers for fire, storm, lightning, theft of the whole boat and damage in winter storage; full cover adds collision, grounding, vandalism and theft of parts. 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 Excess 11 with a berth in Germany and abroad alike. The international certificate of insurance reaches you automatically in ten languages, and taking cover out before the handover pays off, because transport and the first launch are then already covered.
Not to be mixed up with its sisters: this is the Excess 11, number eleven.
