Terhi 400 C: cover, cost and conditions
For the Terhi 400 C 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 Terhi 400 C starts from €49 a year. For a Terhi 400 C at the usual market value of €5,000 the premium is €328 a year: liability and hull in Basis-Plus, inland waters, 110 hp (assumed), hull excess €250, paid annually. Hull cover accounts for €219, liability for €109. Tariff as of 13.11.2026, 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 Terhi 400 C 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 Terhi 400 C, number four hundred.
What is a used Terhi 400 C worth?
A used Terhi 400 C built between 2015 and 2024 in average condition is typically worth between
€4,300 and €12,600 today.
Well kept boats with recent engines sit above that, boats with defects below.
| Year built | typical range | midpoint |
|---|---|---|

| 2015 | €4,300 to €5,500 | €4,900 |
With agreed-value cover, the agreed sum counts after a total loss of your Terhi 400 C;
with actual-value cover, the value at the time.
