Where these answers come from

Every answer on this page is distilled from public boat-owner forum threads. Nothing is generated, and nothing is invented — if the threads never settled on a cause, we say so rather than guess.

—posts read
—diagnostic records
—fault patterns

With thanks to the owners of CanalWorld and Sailboat Owners Forums and YBW, whose members wrote all of it. Every answer links back to the original thread — read it there, and thank the person who solved it.

Gathered by the book. We read and obeyed every forum’s robots.txt, honoured each site’s crawl-delay, fetched one page at a time, and identified ourselves honestly with a contact address. Where a site had put up a gate, we took it as a no. Zero violations.
