Guide value, comparable sales and what a surveyor adds

Updated

Three sources of value get used and only two of them are worth much. Knowing what each is for stops a negotiation being conducted on the weakest one.

Guide values

Published guides price a model, year and general configuration. They are a legitimate starting point and they cannot see your boat: not the hours, not the moisture, not the fact the electronics were last updated a decade ago.

Use one to establish a base, then expect to move a long way from it in either direction.

Comparable sales, not listings

Boats sit on the market and asking prices drift upward from reality. A comparable that sold tells you what somebody paid; a comparable that is listed tells you what somebody hopes.

Where you can get sale prices, weight them heavily. Where you cannot, treat asking prices as a ceiling rather than a benchmark.

The survey is the real valuation

On any boat more than a few seasons old, a survey moves the number more than any other input. Moisture readings, engine condition and structural findings are the things a buyer cannot see and will not risk.

A written survey with itemised recommendations is also the document a negotiation is actually conducted from, which is why sellers commissioning their own is often worth the cost.

Fix or discount

A seller can rectify findings before listing or discount for them afterwards. Rectifying almost always recovers more, because a buyer deducts the cost of the fix plus a margin for the uncertainty of arranging it.

The exception is a finding so large the boat should be sold as a project, in which case pricing it honestly attracts the buyer who actually wants that.

Want the number confirmed?

A calculator works from comparables. A survey or a broker's appraisal is what a buyer, an insurer or a lender will accept. Tell us why you need it and we will pass your details to up to three marine surveyors and boat service firms, who contact you directly.

Start from a base, then adjust honestly

Engine hours, condition and survey findings applied to a guide value, and the checks that stop a sale rather than move its price.
