Dinghies and unpowered craft

For safety  occupants of small unpowered craft using the lock chambers are will be asked to disembark and pull the craft through on ropes. Boaters should note that for safety reasons, vessels must be rowed or under power at all times in the manmade reaches of the canal.

Speed Limit

The Bye Laws of the Caledonian Canal, which have been in force since 1966, require that vessels comply with the speed limits of 6 m.p.h. (5.2 knots) in any part of the canal where ‘the waterway has been raised artificially’ and Skippers are required to pass moored craft at ‘Dead Slow’.

Vessels wishing to enter Clachnaharry Sea Lock should radio the Sea Lock Keeper on VHF Channel 74 or 16 as they pass under the Kessock Bridge. Radio Corpach Sea Lock as the Sea Lock comes in to sight. This allows the Lock Keepers to advise of any boat movements and prepare for your arrival.
