Lock Passage

Practice canal lock sequences with clear reviews and a logbook.

Step into a lock chamber and guide the passage. Choose gate positions. Turn the water level. Set mooring ropes and watch the rope tension change. Select your boat draft and see how it affects the sequence. Earn passage tickets as you complete each learning run, then revisit your choices with a calm, clear review.

Five interactive modes immerse you in the chamber scene, then expand into etiquette drills and canal facts. Use level comparison to contrast recent outcomes. Open the passage logbook to track what you practised and when. Custom Canvas illustrations bring lock gates, water levels, and rope tension to life, with amber accents on dark navy surfaces.

For live canal updates, the app refreshes data from two public sources. If that connection isn’t available, seeded fallback examples keep the experience understandable. No account sign-in is required for the core flow. Work stays close to the first screen. Captures happen quickly. Saved information remains in place for repeat sessions.

Optional Pushwoosh notifications can mark passage milestones, so you know when to come back. Practical organisation supports both short practice blocks and longer review sessions on small or large iPhone screens.
