A tow bar for mooring

One thing we did see on our recent short trip, apart from soaring red kites mobbed by crows, kingfishers streaking ahead of us through overhanging umbrellas of riverside trees, the grandeur of a riverside church lit from below and sculpted by wind blown shadows .... was two permanently moored narrow boats using scaffold poles, hinged at their base on the bank and with a tow bar clip at the river end, clamped to a tow bar that seems to be welded to the deck of the boat.
You have to imagine this clip attached to a triangle of scaffold poles anchored on the bank.

Why this curious arrangement? We think it allows for greater control than a rope, avoiding being pushed into the bank, but able to float upwards with rising water levels. even if the bank was awash the poles would hold the boat in place.
Obviously a solution to a problem when moored by a riverbank such as the Nene and faced with variable water levels.
