According to lock keeper it was 2 private boats going down roped together.
Decided to separate, but only untied each other at the back. One boat went forward, when the gate for the other boat hadnt been opened.
Looking at the gate, I guess that the rope must have impacted on the gate, applying the momentum of two boats onto a very small part of the gate, bending the bottom out of true.
The gate was *not* one of those that was due for replacement over winter, although looking at them it wont have been too long before it was due for replacement. They have fished out of the water one of the pair of gates that they didnt manage to fit on the main part of the flight at the start of the year because of the freezing up. So if it was not for the bad weather then the stoppage would bee for as long as it would take to make a new pair of gates.
Think they are also using the stoppage to get some other work done.
NBW reporting is typical NBW, why let the truth get in the way of your own prejudices.
