Most locks on the canals of central France are still manually operated and a lock-keeper is present. When approaching each lock we will stop well short and put a crew-member ashore to help with the locking procedures. When the gates are open we will go into the lock slowly and moor on the opposite side to the lock-keeper. We will sling ropes (NOT tie them) around bollards both fore and aft which will hold the boat tight against the lock wall. We will help the lock–keeper to open and close the gates but will leave the sluice gates to him or her as the operation of these can be dangerous.
Some locks are automatic and self-operated, such as those at the entrance to both Decize and Nevers and all the locks on the Canal du Garonne. Their operation varies so we plan our entrance to these very carefully with our crew.
"Locking Through" illustrated:
  |
Going Down The boat is secured to the side of the lock by slinging lines around the bollards both fore and aft. |
| As the water level drops, the lines around the bollards are lengthened to keep the boat in place. |  |
It is important to be aware of the sill aft of the boat, which is hidden underwater until the new level is reached. |
|
Once the new level is reached, the lines are released and the boat can proceed. |
|
 |
Going Up As with going down, lines are used to secure the boat against the side of the lock as the water rises. |
| In this direction, the sill is visible so there is less danger of accidentally damaging the boat. |  |
The crew gradually haul in the lines as the boat rises with the water level. |
|
With the water at the higher level, the lines are released and the lock gate opened. |
