C-System; cover, cost and conditions
Four model ranges are recorded for C-System, all under the name Ventilo: the M1 and the M3 from 2013 to 2021, the M2 One Design from 2010 to 2022 and the 18 HT from 1995 to 2001. All four are listed as cabin catamarans. Whether they are sailed or motor-driven is not specified in our data.
For the premium at NAMMERT the data of the individual boat counts, that is the type of boat, value, year of build, propulsion and cruising range. Multihulls are rated by the same rules as monohulls, with no surcharge for the name of the yard. Third-party liability ranges from a limit of indemnity of 10 to 50 million euros.
As production of the Ventilo 18 HT ended back in 2001, these catamarans come into new hands second-hand. We insure regardless of year of build, place of purchase and previous owners, and full hull cover pays out on the agreed value with no deduction for depreciation (new for old). You receive the international certificate of insurance in ten languages.
Questions and answers
Frequent questions
Are catamarans rated differently from monohull boats?
No, not for C-System either: The same features count: type of boat, value, year of build,
propulsion and cruising range.
A cabin catamaran such as the Ventilo M3 is calculated on that basis,
not on its hull configuration or its brand.
Can a catamaran from 1995 still be insured?
Yes, for C-System too: We insure regardless of year of build,
place of purchase and previous owners.
The value is agreed as an agreed value before the policy starts,
and in the event of a claim compensation is paid with no deduction for depreciation (new for old).
