The evaluation report is required usually by leasing companies, insurance companies and by ship owners interested in knowing the real market value of the vessel to be purchased.
For a correct evaluation, expertise must be good not only inspect the boat and check that everything is working properly, but you must know the type and model of boat in question in order to position the exact cost estimate.
We must not forget that there are often yardsticks that affect much business value. There may be two boats of the same model but in dramatically different conditions, or two boats very well maintained, the same length but of totally different construction sites, this can lead to important changes in value.
It is important for those who commission an evaluation report that the expert possesses a very good knowledge of the marine industry in general, in this case the technical skills, though essential, can be considered secondary.
