Safety on the Caledonian Canal


  • Do have an adequate number of competent crew aboard. Single-handed passage is possible but may be subject to delays depending on staff availability to assist.

  • Do take time to plan ahead, lay out warps, fenders, and clear decks before you set off.

  • Do check fuel and oil levels before starting the engine and also that all controls are working properly.

  • Do make sure that children and non swimmers wear life jackets.

  • Do relax and take your time. 


  • Do not speed in the waterway, this damages banks and affects other waterway users.
  • Do not cruise after darkness.

  • Do not cruise near weirs, or attempt to shoot them in canoes. 

  • Do not allow pets to wander – keep them on leads and do not allow them to foul the canal banks.

Tidal operation

Special note should be taken of the tidal restrictions at sea locks. Within normal operating hours, Corpach Sea Lock is available ≥ 1m, and Clachnaharry Sea Lock is available ≥ 1.4m. This restriction for sufficient depth to float the sea lock gates. At low water and spring tides the sea locks are CLOSED 2 HOURS (or a little longer) either side of low tide. 
Contact the Sea Lock Keeper on VHF CH 74 for advice.


Corpach Basin

Corpach Basin is at times used by large freight vessels which require room to manoeuvre, therefore it is rarely available for berthing leisure craft. Please follow the lock keeper’s advice and berth where directed.



Information is contained in the following publications; Pilots: The Admiralty North Coast of Scotland Pilot (NP52) and the Admiralty West Coast of Scotland Pilot (NP66), both of which can be obtained from Admiralty chart agents.

Also in Yachtsman’s Pilots published by Imray, Laurie, Norie & Wilson, and by Clyde Cruising Club.

Charts: Eastern Approaches: – Moray Firth 115, Inverness Firth 1078, Caledonian Canal 1791. Western Approaches – Loch Linnhe (North) 2380, Fort William and Corpach 2372.

Jetties and transit moorings

There are transit jetties adjacent to most locks and bridges. Please check with lock keeper as to the best place to berth, particularly if you plan a long stay. During the summer season, it is helpful if skippers of large vessels (LOA ≥ 15m) call the canal office prior to arrival, to allow planning of overnight berthing on passage.
