The Alsace with Crown Blue Line

The Alsace: Lock Technique
Before going on the Crown Blue Line charter, I read up on the various types of locks to expect and the techniques available to negotiate them. The books are numerous on the subject, but I generally found that the Alsace Guide and the Manuel du Capitaine, both supplied by CBL, broadly summarised exactly what all the books advised.

To negotiate a lock downstream seemed to require a team of three people. Two crew members man the bow and stern lines whilst the third member leaps ashore to receive slip the lines around the nearest bollards and then operate the lock mechanism. Once the lock is empty, the crew member thats ashore, releases the lines and climbs down the wall ladder to board the boat again.

Lock Techniques
Going upstream through a lock is the inverse of the above. A crew member climbs the wall ladder to receive and slip the bow and stern lines from the two crew left on board. The lock is activated and flooded by the shore crew member who then simply hops on board when the boat leaves the flooded lock.

What troubled me in this research, was that we were a family of four with two very young children and the eldest of 7 couldn’t be relied upon to be an affective member of the crew- not safely any way. This meant there was only my wife and myself to do the work of supposedly three people.

The first half of the cruise was a descent through the locks and naturally things didn’t go well through the first few locks - it was a mess, and not really helped by the fact that between the two of us we had to keep half an eye on Edward, William (3) was not a problem since he was harnessed on.

We had just entered a flooded lock starboard side on, and whilst struggling with the bow and stern warps, our saviour came from a French lock keeper who instantly understood our difficulty. He could see that the boat was properly warped up at every quarter and so quickly grabbed the aft starboard warp, led it up to the midship kleat, put a hitch around it and slipped the remaining tail of the warp around a bollard. Within a brief few moments, he had simply thrown away all that was said in the manuals and text books. "No need for bow and stern lines", he said, and the boat was simply held to the wall by a single slip amidships. What was written in the manuals for a crew of three, could now be done by one. From then onwards descending the canal locks was a singe.

The conventional technique using a crew of 3 The single handed technique

Going upstream and ascending the locks presented a new problem for us. This time we were entering empty locks with 3m high walls, sometimes higher, making the bollards well out of reach. Sending Louise ashore up the wall ladder was out of the question for I daren’t leave the con to handle the warps. From the corner of our eyes we could see some very skilled crews from other boats, throw up a coil of line towards a selected bollard where it would specularly loop itself around the bollard and form a slip. We tried to imitate this to no avail and quickly got ourselves no where. Alas! the French showed us the solution again. Still maintaining the midship warp arrangement, Louise stood at the flybridge and placed this warp in the crook of the boat hook and carefully extended out the pole of the boat hook whilst still holding the tail end of the warp in her other hand. The warp is then simply placed over the bollard and the boat hook is then withdrawn. Louise then passed the slip for me to hold whilst remaining at the con and she did the same procedure with the bow line, but this time holding on to the bow slip herself. This arrangement meant that every bollard was within reach and without the need for a single crew member to go ashore. Unlike a descending lock, we were slipped fore and midships which is necessary in a flooding lock for the inrush of water is very turbulent and can knock the boat about a bit. The more boats in a flooding lock the better and easier it is. Once the lock is flooded, then the warps are simply flicked off the bollards and away you go.

This technique showed that a team of two can negotiate the canals very easily.

Using the boathook as a means of placing the warps around the bollards which are kept out of reach- typical when entering an empty lock.
