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.
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.
Drop a broker sheet, a PDF, a screenshot, or paste a listing address. The specification reads itself into the worksheet, several sales at a time. Typing it out by hand is the fallback here, not the job.
Region, condition, equipment, hours, hull, fuel — each one a single field. They stack additively and never compound, so every figure can be recomputed by hand by whoever is reading it.
Prepare as a surveyor or as a broker. The concluded figure is identical either way; the document is written for whoever will read it — the full account of the method for a lender or an insurer, a clear range and comparative graphics for an owner.
Drop in your sold comparables. Set the adjustments that matter. Take away a document with its reasoning attached — the ledger, the narrative, and every exclusion named. Whether it goes to a lender or across a kitchen table, the working is right there on the page.
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.

Marlin Rise was excluded as a distressed sale and is named here for that reason — the document discloses it rather than dropping it.
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, or download a self-contained page or a PDF. Your firm name, credentials and logo are on it. Signed in, every valuation is kept in My valuations as you work, drafts included, so you can come back to it.
These are not preferences with a switch. They are what makes two documents produced months apart comparable to each other.
Every figure, every adjustment, every line of the ledger and every sentence of the narrative comes from fixed rules applied to the evidence you enter. The same entries give the same answer every time, and every step can be checked by hand.
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. Sign in or create an account, bring one vessel and three or four recorded sales, and you will see the shape of the finished document in a few minutes.
