Lockmaster AI

Lockmaster AI is a free navigation companion for the inland waterways of the UK, Ireland and mainland Europe — built for narrowboats, widebeams and cruisers.

Plan your cruise, find your way through locks and bridges, and see what lies ahead on the water. Lockmaster informs; the skipper decides.

SAFETY FIRST
Lockmaster shows you the facts — official stoppage notices, published dimensions and authority data — and leaves the decision where it belongs: with you, the skipper. We never tell you a route is "safe" or "clear." You read the information and make the call.

An optional SOS feature can send your position to an emergency contact you choose. It does not contact 999/112 or the emergency services.

FREE, NO ACCOUNTS, NO ADS
Lockmaster is completely free. No sign-up, no subscriptions, no advertising. Your boat profile and settings stay on your device.

Data sources include Waterways Ireland, the Canal & River Trust, EuRIS, national waterway authorities and OpenStreetMap contributors, with full attribution at lockmasterai.co.uk/data-sources.

Weather, river levels and gauge data help you understand conditions before you set off.
