Mariah SX 18: cover, cost and conditions
The Mariah SX 18 is a motorboat that is already insured with us, and four further models of this brand are recorded. No details on dimensions and engine equipment are available, which is no obstacle to taking out the policy and to the classification.
Whether you are travelling on an inland lake or on the coast has an effect on the premium. Alongside the type of boat, value, year of construction and engine power, the cruising range is one of the details we need for the classification. If it changes, let us know beforehand.
Hull cover has no time window and no night clause. It also applies in winter storage, during craning, during launching and in transit. A boat trailer is covered by the third-party liability at no extra premium from Basis-Plus, provided it is named in the application with its value, and switching to us is arranged through our free cancellation service. You can add it to the hull cover for a premium.
