Six quotes, one boat: what a market survey actually shows
The interesting part of a market survey is not the cheapest premium. It is the two providers whose wording turns out to insure something different.

For the survey dated 1 July 2026 we asked six providers in the German market to quote the same two craft: a jet ski of 115 hp, built 2023, insured value 11,500 euro, and one of 250 hp, built 2026, 30,000 euro. We did not only compare premiums but 23 coverage points taken from the original policy wordings.
On price we are not the answer for everyone, and the survey says so. On the jet ski, one provider came in at 841.93 euro, roughly 328 euro below us. On the houseboat we were the most expensive quote in the field at 1,651 euro. Both figures are published on our German pages with the reasoning, because a comparison in which one provider wins every line is not a survey.
The finding that matters more is about wording, not price. Reading the six originals side by side showed that one provider insures jet skis on a named perils basis: collision, grounding and operating error simply are not in the list. Two of the six will not insure racing or training at all, and none of the five competitors offered a seasonal policy.
That is the difference a price comparison cannot show you. Named perils and all risks are not two grades of the same product. In an all risks wording the exclusion list is the actual description of cover; in a named perils wording only what is listed is insured, and the list is usually shorter than a buyer assumes.
Every line in the published comparison carries its own provenance: either the quoted passage from the policy wording or a note that it comes from our own enquiry. Where we hold no reliable source, that is stated and the line does not count towards the totals.
Common questions
Do the premiums apply to a boat kept outside Germany?
No. They were quoted for a German domicile. Domicile and flag both feed into the rating, so a quote for another country can differ substantially.
How do I tell whether a wording is all risks or named perils?
Look for the list. If the document enumerates insured events, it is named perils. If it enumerates exclusions and insures everything else, it is all risks.
