Neptun 31: cover, cost and conditions
The Neptun 31 is recorded with us as a trailer, it is already represented in our portfolio, and ten further models from Neptun are on record. For boat owners this raises the question whether the trailer needs a contract of its own.
It does not. Boat trailers are covered by the third-party liability at no extra premium from Basis-Plus, provided they are named in the application with their value as long as they belong to the insured boat. You can add them to the hull cover for a premium. You pay no surcharge for this, do not have to have it revalued every year and also need no second contract alongside.
In keeping with that, cover applies while craning, launching and on the transport route as well as in winter storage. This means the way from the shed to the ramp and back is not the stretch for which nobody is responsible. For journeys on the road, the statutory motor third-party liability of the towing combination remains unaffected.
