Terhi 400: cover, cost and conditions
Terhi 400: 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 Terhi 400: On a motorboat the drive is the single most valuable part. Damage after grounding or collision is covered under full cover, an engine failure from wear is not. If an outboard sits on the transom it belongs in the policy with make, output and serial number, otherwise a theft claim settles the hull alone.
What does cover for a Terhi 400 cost? The premium starts from €49 a year. 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 Terhi 400 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 Terhi 400, number four hundred.
