This short, cruiser-sterned narrowboat is up to the windows in dirty canal water at its mooring off Waterloo Road, Uxbridge, spotted from the Rockingham Road canal bridge.
The cause of the sinking is not known. Boats go down for a number of reasons, including slow leaks, ice cracking the hull in winter or water getting in through a faulty valve or drain.
At least this one can be refloated, drained, dried and repaired. The boater's worst nightmare is fire on board, which can destroy a vessel in minutes.
