One day we’ll write a post which looks at the relative merits of river cruising and canal cruising but one of the greatest differences is that canals have more locks. To give you an idea: so far this year, we have travelled nearly 200km up the Saone (including the occasional detour) and encountered 20 locks along the way. In the 67km we have so far travelled on the Canal des Vosges, we have been through 60 locks. Most of them are automatic - set in motion by a combination of a remote control unit, which registers your presence upstream or downstream of the lock and your wish to pass through the it, and a vertical pole recessed into the lock wall, which you lift up to activate the filling or emptying of the lock.
On this canal, the locks have been relatively standard: you “step” up or down around 3 metres at each one, the position of the bollards has been more or less consistent and in all but 2 of the locks the mechanism was on the same side. All these factors are important in terms of working out how to approach the lock. We could manage the 3m step up with both of us on the boat but it was towards our limit. When we came across a series of 5 locks with a step up of between 3.25 and 3.5 metres, we decided to take our alternative approach, which involves C on a bicycle dropping a rope down to J in the boat.
As we approached the fourth lock in the series - lock number 25, called La Colosse but actually one of the smaller of the five - we were met with two red lights, which means that the lock is “Not in service” for some reason, always unknown to us. We have yet to be told of any recommended course of action when this occurs so we waited. After what seemed like a respectable amount of waiting time, C cycled up to the lock to use the intercom there to contact the navigation services (VNF) but a VNF van pulled up at the same time with three men inside. One of them told C that there was a problem with the lock but then played with a few buttons on the control panel (which is locked inside a little hut at the lock) and we were presented with a green light and open doors. With all seeming to be in order, the VNF van drove off.
We set the boat up in the lock, pushed the lever to set it in motion and almost immediately saw another boat coming round the corner behind us. If we had known they were there, we would have waited for them and locked up together but having set the lock in motion, there was nothing we could do to stop it except pull the red emergency lever - and the situation didn’t seem to warrant that! The lock doors started to close and we waited for the lock to begin to fill. And we kept waiting…
When it was obvious that the lock wasn’t going to fill (and we’d given another push or two on the lever just to make sure that we hadn’t somehow muffed the process in the first instance), C did get to use the intercom system to alert the VNF to the problem and the person she finally got to speak to assured her that they would send someone “tout de suite”. When something goes wrong on the waterways, the worst thing is often not knowing what the problem is nor what you might be expected to do in response to it. For this reason, C biked off to communicate the situation to the agitated Germans in the boat behind and then to the somewhat more relaxed Irish couple in the barge, Tara, which had since appeared upstream.
And so we waited…and waited…and waited; J in the boat in the bottom of the lock, C with her bike at the top of it. By the time at least 45 minutes - and midday - had passed, C tried the intercom again to see if some sort of update might be possible but it steadfastly refused to allow her to communicate with anyone. (The call had been registered; perhaps they’d then switched the thing off.) In a further lack-of-progress update with the captain of Tara, C suggested that if he had a mobile phone, maybe he could use that to ring the VNF again and innocently inform them of a problem at the lock from his newly-arrived-upstream perspective. He’d agreed to do just that when, right on cue, a VNF van pulled up - this time with just one man inside but the right one. He was in charge of the 10-lock sector and he swung into action immediately.
First of all he asked us to move forward in the lock to make room for the German boat. He opened the doors and they tied up at the back of the lock. Their boat was a small one we didn’t have to move far to make room. The next step was to close the doors, which he tried to do but they never fully closed. After many unsuccessful attempts, he surmised that the problem was a rock or stone in the way of the lock doors, probably thrown up by a barge which had passed us just as we were coming out of one of the earlier locks. It seems that if barges accelerate too quickly out of locks, they can throw up all sorts of things that had previously been resting harmlessly on the canal floor. The barge pilots are therefore requested to go gently out of the locks but this one had ignored the request. There was nothing for it but for our VNF chief to head away to the next lock in his van to get a suitable implement to clear the stone from the lock doors.
While he was away, I kept providing updates to those around: in awfully rusty German to our neighbours in the lock, who spoke very little French and even less English, to the captain of Tara, who passed them on to the growing collection of boats upstream and to a very relaxed Dutch couple, who had arrived at the lock from below.
The VNF man returned after a short time with something that looked like this:

As you might imagine, this is not the easiest tool in the world to use, especially not alone, from a height of around four metres above the water line and at least two below it, and in sweltering heat! We watched as he made repeated gallant attempts to clear the offending stone and were impressed and optimistic when he finally pulled up a large concrete block from the depths. With NZ and French fingers crossed and German thumbs pressed for good luck, our VNF man had another go at the control panel. But no, the doors jammed at exactly the same point, just millimetres short of being fully closed.
At this point, more serious help was obviously needed in the form of scuba divers, so this was once again a job for the fire brigade. The VNF man put in the call and then left to meet the divers, who would be coming from Epinal, a good 20-30 minutes away. After another bike ride up and downstream with the latest update, we decided it was time to have some lunch. J prepared a salad in the boat, put C’s in a bowl inside a plastic bag and C was able to drop down the rope to attach it to so she could bring it up to the top of the lock.
Meanwhile, our 3 VNF men in a van from the beginning of the saga appeared on the scene once more. They valiantly tried to resolve the problem by:
a) repeatedly opening and closing the door using the controls in the hut
b) having a go at clearing the obstacle with the giant rake
c) sending one man into the water for a dive to see if he could clear things that way.
While the last attempt was in progress, the Sapeurs-Pompiers van arrived from Epinal. In true French fashion, he got out of the van, greeted each of the VNF employees with a handshake and was provided with a full update on the situation. No problem, he said, as soon as his colleague arrived, he would be in the water and sure to have the blockage cleared. For health and safety reasons, he was not allowed to dive until a suitably qualified colleague was present to assist him - and that colleague had to come from Vittel. (It should be noted that this is possibly the first obvious example of safe workplace practice we have witnessed in France, a land where no-one seems to have heard of masks, safety goggles or ear muffs and where VNF employees dive happily into the canal to try to free up the lock gates with blatant disregard for any rules to the contrary.) Given that the arrival of the van from the fire brigade had raised expectations of action up and downstream of the lock as well as in it, C decided that another multi-lingual communication mission was in order to lower those expectation to a more reasonable level.
Around 25 minutes later, the fireman from Vittel arrived, got out of his van, greeted his colleague from Epinal and each of the VNF employees with a handshake and received his update on the situation. Now supervised not only by his colleague from Vittel but also by four VNF employees, several boaties and a couple of passing cyclists, the diver from Epinal finally went into the water. After no more than about 5 minutes, he had filled a large bucket with fist-sized pieces of building material and announced that that seemed to be everything.

So, just over three hours after J first entered the lock, there we all were again waiting for the lock doors to close with French and kiwi fingers crossed and German thumbs pressed…and yes, this time it did work. The lock duly filled and J was finally out of there! No updates were needed at this point - the passing boats and changing lights at the locks told the waiting boaties all they needed to know. As for us, well, we completed the last of the five high locks without incident and immediately started to look for a suitable mooring for the night. All that inaction in sweltering heat had taken its toll - we needed a rest!
