Safety on the Crinan 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. 

Don’t

  • Do not ask members of the public to handle your ropes or walk vessels through locks
  • 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
Important Information

Vessel Draft & Navigation 

Maximum lock dimensions:

Length: 26.8m (88ft)

Width: 6.1m (20ft)

Fresh water Draft: 2.4m * (8ft 10in) 

Air draft: 29m (95ft)

* Note that water conditions continually change and that the maximum draft cannot be guaranteed. Consult the sea lock keeper for the maximum draft of the day. During drought conditions the maximum draft is considerably lower than in the rainy season and managed daily.

Please add at least 100mm (4 in) to your saltwater draft for calculating your draft in the canal. Boats sit deeper in fresh water than salt water. 

Due to possible weather-related level changes, customers with a draft of more than 2.2m should always check with the appropriate sea lock 24 hours in advance to confirm the available draft for the date of passage.

 

Single Lockings 

Please note that we will hold single vessels to make effective use of the lock. Where a single craft “splits” from a group that vessel may also be held for a period to join another locking. 

We will endeavour not to cause undue delay and hope that your co-operation will help us maintain levels of service throughout the summer period.

VHF Radio

The sea locks work on Channel 74. 

Please note when our team members are performing locking or maintenance duty they will be unable to respond to VHF calls. 

If you do not get an immediate response, you can contact the Crinan Canal office, or approach the lock if open to the sea - it is likely that the Lock Keeper has spotted you.

Speed limits

Please observe the speed limit on the canal to help avoid bank erosion through excessive wash and please slow down when passing moored craft. The final approach to Crinan between Crinan Bridge and Lock 14 is narrow, with moored craft lying above Lock 14. Please exercise caution while transiting this section of the canal.

 

Use of locks after closedown

Do not use the canal locks after the canal has closed for the day as water levels are adjusted for the following day and any unplanned locking can lead to flooding or water loss.

 

Cill markers

To avoid possible contact with the lock cill please ensure your vessel does not pass the cill marker on the lock wall and remains clear of lock gangways during lock operations. If you are in any doubt please ask Scottish Canals staff for advice.

 

Local restrictions

Please note that to maintain access for emergency vehicles we are unable to rotate Ardrishaig Sea Lock Bridge and Lock 4 Bridge at the same time and must also comply with slight restrictions during school term time, both of which may cause short delays to boating traffic.
