Read the water.

Tap a gate on the canal. Send one mark of water up or down. When the two chambers match and the boat has enough draft, sail through.

Docking and scoring

Bring the vessel into the arrival dock at its marked water level. Every valid move counts. A blocked action counts as an attempt, Undo costs one move, and a hint costs two. Replay a lock to improve the local best count. Clearing a lock opens the next one.

One-way valves

Some later gates have one-way water arrows. The arrow indicates the permitted transfer direction; boats may still sail either way when water marks match.
