About Boat Value Calculator
What a boat is worth, and why the survey moves the number more than the guide does
What is on this site
One question, "boat value calculator", answered with a calculator that works on the page with no account, 3 guides on the questions around it, a data table you can cite (the figures and their method), and the sources every figure rests on.
- Guide value, comparable sales and what a surveyor adds: Guide values are a starting point. What comparable sales and a survey add, and why asking prices mislead on boats.
- Engine hours: the adjustment that dominates most powerboats: Hours matter less on their own than hours against expected use and service history. How buyers actually read them.
- What to check before a price is agreed: Title, liens, documentation and dockage. The checks that stop a sale rather than adjust it, and when to do them.

Boat Value Calculator is an independent site operated by Ellul Solutions Ltd. It is not affiliated with, endorsed by or connected to any agency, association or company named here. Nothing on it is valuation, survey, insurance, legal or tax advice. We take no commission and carry no paid placements. This tool produces an indication from a base value you supply and adjustments you choose. It is not a valuation and not a survey, and no depreciation curve or standard adjustment is published here because used boat values vary by hull, engine, region and season. Only a qualified marine surveyor can assess a specific vessel, and title, lien and documentation questions are for the relevant registry and your own adviser.
