"A narrowboat that was left teetering on the edge of a giant hole after part of a canal in Shropshire collapsed has been pulled to safety. Paul Stowe's boat, the Pacemaker, was perilously close to falling into the hole on the Llangollen Canal in Whitchurch, which opened up on Monday after an "embankment failure" Very good news. Welldone to all in the rescue & canal services that facilitated this.
They have got both sides of the breach back in water now which is pretty good going. It’s the repair that will be the hard part.
