This is that barge, called 'Grand Cru', a floating studio, moored on the tidal river Thames, just outside Pete Townshend's studio.
Note the dry patches in the river - it is ebb tide. The barge has its own dry place to sit on. That leads to her leaning slightly forward, hence the producer's chair that rolls away from the mixing console.
Part of the day this is not a floating studio at all...
I have blogged about this subject before
