How it works, what you get, and what it costs

HOW IT WORKS

From pasted URL to final go/no-go

Knotworth reads the listing the way a skeptic would: what's claimed, what's silent, and what a boat this age typically needs. Then it prices the gap, writes your seller questions, and recomputes as answers arrive.

SAMPLE REPORT

A real report, opened up

A 2004 Bavaria 38 listed at €58,000, with a true cost of €71,400 to €89,200 once rigging, sails and taxes are priced in. Walk through the condition read, the cost table and the negotiation case it produced.

PRICING

One payment per boat. No subscription.

The pre-check is free for every boat you're eyeing. One fixed payment unlocks a boat's full report, unlimited recomputes and the negotiation evidence case. You never pay to be told an easy no.
