Caledonian Canal Skipper’s Guide
Our Skipper's Guide tells you everything you need to know about boating on the Caledonian Canal.
Safety on the Caledonian Canal
Do
- 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.Â
Don’t
- 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.Â
Within normal operating hours, Corpach Sea Lock is available ≥ 1.3m, 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.Â
Contact the Sea Lock Keeper on VHF CH 74 for advice.
Â
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.
Â

Safety first
Insurance and Boat Safety Scheme
InsuranceÂ
You must have in place a valid insurance policy for your vessel which covers third-party liabilities for at least two million pounds. The policy must also cover cost of recovery if your vessel takes on water or sinks. A valid copy must be provided to the local waterway office or sea lock upon arrival. Â
Boat Safety CertificateÂ
All those berthing within the canal system for periods in excess of 30 days must obtain a Boat Safety Certificate or equivalent.Â
Owners using the canal for less than 30 days will be subject to spot checks to ensure their craft meet the standards of safety required under the scheme. Checks will cover the gas system, electrical system, and will be visual or in the case of the gas test carried out by use of a leak detector
Speed Limits
The maximum speed permitted on the canal sections is 5 knots, but please plan your passage with leisure in mind since excess speed not only damages canal banks, but is hazardous to other users. Please slow down as you approach locks and bridges, and also whilst passing moored craft. Vessels found to be speeding may be held back by canal staff.
VHF Communication
Sea locks and most locks and bridges are equipped with VHF and operate on Channel 74. Please keep your VHF Radio switched on!
Radar
Masters are requested to ensure radar scanners are switched off whilst craft are within or approaching locks.
Swimming
Please do not swim in the waterway, you could become entangled in weeds, be hit by a passing craft or be drawn into a sluice when locks are in use. The results could be fatal.
Large Vessels Warning
Large commercial vessels operate on the Caledonian Canal. These craft normally have right of way and it may be necessary to stop smaller craft for short periods. For your safety please adhere to Scottish Canals’ staff instructions at all times.

Please note that no discharge of oil or bilge water is permitted either in the canal or its adjacent waters and any contravention of this ruling will result in notification to the MCA and may render you liable to prosecution by the Scottish Environmental Protection Agency (SEPA). Emergency discharge facilities can be arranged using specialist contractors at additional cost - please contact the canal office for advice.
