The Iconoclast.

'The Iconoclast' is a houseboat which floats for one hour twice a day.
Lifted by the River Thames, the tilted tonnage sways.
If only briefly and in extremes, according to the tide.
'The float' is a full circle, a tranquil point in which to languish beyond eleven hours of slant.
This bohemian vessel has no history of razing icons to the ground, contrary to the name.
However, the houseboat is moored beneath the twin towers and the cathedral facade of a disused power station.
And this lends a backdrop, or an aspect to the theme.
