Seamaster 813: cover, cost and conditions
For the Seamaster 813 we do not price by model name. The premium comes from five entries in the online calculator: type of boat, year, value, engine output and cruising area.
The premium for a Seamaster 813 starts from €49 a year. For a Seamaster 813 at the usual market value of €14,000 the premium is €570 a year: liability and hull in Basis-Plus, North Sea, Baltic and Mediterranean, 225 hp (assumed), hull excess €250, paid annually. Hull cover accounts for €421, liability for €149. Tariff as of 03.11.2026, your own boat may differ. How much hull cover adds depends on the value: partial cover pays for fire, storm, lightning, theft of the whole boat and winter storage damage, full cover also for collision, grounding, vandalism and theft of parts. On a total loss we pay the agreed value, in Premium with no new-for-old deduction.
Whether bought used, brought in from abroad or ordered new, we write the Seamaster 813 with a berth in Germany or abroad. The international certificate of insurance arrives automatically in ten languages. Take cover out before the handover and transport and the first launch are already insured.
Not to be mixed up with its sisters: this is the Seamaster 813, number eight hundred thirteen.
