The Valuation Challenge

What's
she
worth?

Three boats on the market right now. Guess what each one is advertised for — we'll show you what the market says.

Live at Cannes 8–13 September 2026

Can you make the Cannes top 10?

Best played on mobile — one thumb, held at arm's length.

How it works

You guess the
asking price.
We show what
it's worth.

Two different numbers. The asking price is what a broker published — that's the one you're scored on. Our estimate comes from a live index of more than 50,000 listings, and the gap between them is the interesting bit.

      Yours is a different question — and it deserves a proper answer.

      The game is entertainment about boats on the market. A valuation of your own boat happens in the owner app, with your spec, your refit history and your cruising ground.
