Worth knowing
Seamaster; cover, cost and conditions
Seamaster cruisers are British inland and coastal boats from the sixties to the eighties, in Germany mostly under way on canals and lakes. On boats of this age the electrical system is the issue, especially on imports with a different shore power standard. Fire is covered, and it can be avoided with a professional conversion.
The second point is the valuation. For boats that have been cared for over decades, a calculation based on the current market value gives no sensible result. Agree an agreed value based on the replacement value, and then it is clear in the event of a total loss what will be paid.
Questions and answers
Frequent questions
Is the shore power connection a risk?

Have it converted professionally; it is one of the most frequent causes of fire on board.
How do I value an old cabin boat?
For Seamaster: By the replacement value on the German market, as an agreed value in the contract.

Series by Seamaster, with value and cover
Seamaster 23 / 27 is a motorboat from Seamaster (the United Kingdom), built from 1965 to 1985,
and today changes hands at between €6,000 and €22,000.
Seamaster 30 / 813 is a motor yacht from Seamaster (the United Kingdom), built from 1970 to 1990,
and today changes hands at between €14,000 and €45,000.
For the Seamaster 23 / 27 and Seamaster 30 / 813 by Seamaster series there is no list price left.
That is why we work with an agreed value: you state the figure, we agree it,
and in a total loss exactly that amount is paid, with no deduction for wear.
For the Seamaster 23 / 27 by Seamaster series:
On a motorboat the drive is the single most valuable part.
Damage after grounding is covered, an engine failure from wear is not.
For the Seamaster 30 / 813 by Seamaster series:
On motor yachts the drive and the electronics together make up about half the value.
Both belong in the valuation, otherwise the sum insured is too low.
