A valuation is not normally included with a survey report and you will need to request one if this is required.
An additional fee for providing a valuation will normally be charged. The "current market value" incorporated in the valuation may be relevant both for purchase and insurance purposes. It is based on, amongst other issues, the price that a willing buyer will pay a willing seller. A keen buyer who has researched the market thoroughly will have perhaps the most up-to-date knowledge of likely value of a particular vessel type, however, a surveyor normally has access to accurate information regarding the actual sale price (rather than advertised price) via specialist websites and other surveyor and broker colleagues, as well as his understanding of the condition of this particular vessel.
