Dean Colin Slee has sailed up the Thames with several representatives of the cathedral congregation as part of Beating the Bounds of the parish.
Dean of Southwark and party head for cathedral's parish boundary in the Thames
The ancient Rogation Sunday custom, once an annual event in Southwark, involves visting the parish boundary stones and praying for those living and working within the parish.
The northern boundary of the cathedral's parish runs along the middle of the River Thames. The boat sailed upstream from Hay's Wharf to Bankside Pier pausing opposite the cathedral to allow passengers to lean over the side and beat the water.

The procession, led by a cross, took 90 minutes to circle the parish. At each stop prayers were said by Canon Pastor Bruce Saunders for residents, workers, school children and medical students. There were also prayers for those affected by change in the area.
