The valuation survey is conducted by an accredited valuation surveyor. The idea is to establish the value of your vessel so the government will know what taxes and duties should be charged. Often vessels are valued at much less than what they will be sold for to reduce taxes and duties for the importer. In our case, our 1979 Dufour 35 was valued at $19,000 AUD and we sold at $54,000 AUD. We have been told that the valuation typically comes in at half of what the boat will sell for. Nobody but you, the surveyor and a government representative will see the survey, so there is no risk of actually devaluing your boat to prospective buyers.
