Mariah 21 SC: cover, cost and conditions
For the Mariah 21 SC a motorboat is recorded that sails in our portfolio; four further Mariah models are recorded with us. Further data on this model are not available, and we do not add anything that is not documented.
In winter storage more damage occurs than many expect. Limited hull cover bears damage there as well as fire, storm, lightning strike and the theft of the whole boat. Craning, launching and the transport route are also included, with no time window and no night clause.
The premium follows type of boat, value, year of construction, engine output and cruising range, never brand or model name. If you switch to us, we cancel the previous contract free of charge. 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 online conclusion is possible up to a sum insured of 2. You can add it to the hull cover for a premium.5 million euros.
