Bridges and Narrow Aqueducts

It is an unwritten rule of the waterways that if you are going to meet another boat then it will be at a narrow section such as a bridge hole or an aqueduct.

Protocol says that the one closer to the narrowing has priority but consider other elements such as the position of moored boats and whether they make it easier or harder for either of you to manoeuvre.

It is also usually easier for the boat going upstream on a river or the boat nearest the towing path, (many people say towpath), on a canal to give way. If you think it is easier for you to give way first then do so, even though you might normally have priority.

If you are in a convoy, or are meeting a convoy of boats, then take it in turn to pass through the restriction. There might be exceptions to this, like the Pontcysyllte aqueduct, where local rules may apply.

When giving a signal for the other boat to come through wave with your arm out to the side so the other boater will be able to see your silhouette.

If you hold your hand out in front of you and draw your hand toward your face then even the best sighted helmsmen may have difficulty seeing your signal.

If you think the other helmsman may not be watching then give a flash of your headlight to attract attention. Use of the horn is discouraged in this sort of situation because it could be misinterpreted. See "Sound Signals" in the "Boaters Handbook". (See the Homepage for the link).
