Williams DieselJet 445: cover, cost and conditions
The Williams DieselJet 445 measures 4.5 metres in length and 2.01 metres in beam and belongs to the Dieseljet 445 and 505 model range, which has been built since 2012 up to today. It is listed with us as a tender, and seven further models of the brand are recorded.
A tender is moved, exchanged, put on land and launched again. Full hull cover includes collision, grounding, vandalism and theft of parts including the outboard and pays compensation at the agreed value with no deduction for depreciation.
The cover also applies in winter storage, during craning, during launching and in transit, with no time window and no night clause. We issue the international certificate of insurance automatically in ten languages, so that it can be read abroad.
