## What is Keelbook?

Keelbook is a private maintenance logbook for UK narrowboat owners.
Log engine hours with large gloves-friendly controls. Record pump-outs and water fills. Keep one current expiry each for BSS, CRT licence, and insurance, with optional local reminders 30, 7 and 1 days before they fall due.
Everything stays on your iPhone. There is no account, no cloud sync, and no advertising.
Keelbook is a personal logbook and reminder tool. It is not legal advice, CRT evidence, or an insurer certificate.
