Frank Noble saw his home, a canal barge, suddenly plunge underwater in a canal lock. I have heard of homes being swallowed up by sinkholes but sunk in a canal is a first. According to Manchester Evening News, as the lock filled with water the back end got pulled under the surface. The whole boat was submerged very quickly. Fortunately Noble was not aboard but everything he had aboard is a loss. The lock was drained so he could pump water out of the boat and then refloated when the water was let back in. Other boats were stranded during this process.
As to how it happened, one posting at the news site suggested the bow got caught in the exit gates forcing the stern down till it flooded. Comparable to Titanic? No. And one commenter asked in jest “ where is the Ice?”
