Worth knowing
T. S. Marine; cover, cost and conditions
One motor boat is listed, the Sea Nymph 520 from the years of construction 1973 to 1980. Boats like this change hands today on the second-hand market, often without complete papers. We insure regardless of year of construction, place of purchase and previous owners.
When buying, what counts is the value you record in the policy. The agreed value records the replacement value and is used in the event of a claim with no deduction for depreciation. In the Premium tariff it applies with no age limit, regardless of the age of the hull.
If a dispute with the seller or a yard arises after the purchase, the legal expenses cover for water sports that we also offer takes effect. Beneath it sits third-party liability with a limit of indemnity of 10 to 50 million euros as the basis of the policy. Limited hull cover and full hull cover build on it.
