A valuation worksheet for marine surveyors and yacht brokers. It applies one method consistently, shows every step of its working, and names what it set aside and why — so the figure arrives with its reasoning attached.
You bring the sales data. This tool has no sales database and cannot fetch one. It is built for marine professionals who already hold their own subscriptions to sold-sales resources — BUCValu, Soldboats, BoatWizard. Without access to recorded sold prices, it has nothing to work from.
Valuation work goes wrong quietly. An adjustment applied one way this month and another way next; a comparable dropped because it was awkward; a figure that cannot be recomputed by the person reading it. This tool exists to make those things hard to do by accident.
You can exclude any sale. What you cannot do is hide that you did — an excluded comparable is named in the finished document with its reason. Silently dropping inconvenient evidence is the thing this tool exists to prevent.
Adjustments stack additively and never compound. Ten percent and five percent make fifteen, not fifteen and a half. A figure nobody can recompute by hand is a figure they can dismiss.
Not by model year alone. A 2021 boat that sold in 2021 was nearly new; the same boat selling in 2025 was four years old. Those are different evidence, and they are treated so.
Sold prices are the basis. Listings appear as market context, and become a working basis only after an expected-sale deduction measured from your own comparables.
Every data section takes a dropped PDF, a screenshot, or a listing address and reads the specification out for you. A screenshot of a results table beats retyping the table.
A comparable needing a very large adjustment, or landing far from its peers, gets flagged for review — a prompt to look, never a verdict. The decision stays yours.
A document defending a figure to an insurer and a document opening a conversation with an owner are not the same object, and pretending otherwise serves neither. Choose who you are addressing; the worksheet does the rest.
Its reader is a bank, an insurer, a court, or a client's advisor — someone who was not present and is looking for reasons to doubt it.
Its reader is the seller, or a prospect deciding who to list with. Its job is often to help an owner's expectation meet the market.
The concluded figure is identical either way. Switching mode changes who is being addressed, never the arithmetic. There is one calculation, so there is one answer to defend rather than two.
Drop a broker sheet, a spreadsheet export, a PDF or a screenshot — or paste a listing address. Several sales can arrive in one pass. Typing it by hand is the fallback, not the route.
Region, condition, equipment, hours, hull material, fuel, water use. Several adjustments set their own direction once both vessels' attributes are known, so the tool declines to guess where it cannot tell.
Copy the ledger, the narrative or the value statement; download Word or a self-contained page; or print to PDF. Your firm name, credentials and logo are on it.
These are not preferences with a switch. They are what makes two documents produced months apart comparable to each other.
Firm name, credentials, contact details and your logo sit on the finished document. Drop the logo file straight onto the block and it is on every page you produce.
Small explanation panels sit beside the controls that need them, and a built-in guide answers questions about your open worksheet — what a flag means, which comparable it is talking about, what to do next. It explains; it never overrides the figure.
Nothing to install and nothing to set up. Bring one vessel and three or four recorded sales, and you will see the shape of the finished document in a few minutes.
