A visit to the gardens of Beth Chatto, near Colchester in Essex, produced the photograph above. The pond is one of a series that have been created on a slope in the garden and it features this rowing boat. I imagine the boat is used with serious intent only occasionally. However, it supplies a semi-permanent focal point in this section of the garden as an eye-catcher. Most garden eye-catchers are on land; statues, pavilions,mock ruins, sun dials, etc are typically used. Where there is water it can be a boat house on the shore, a fountain or perhaps a building on an island. I've never seen a boat used in this way before, but it works, not only for this section of garden, but also for a photograph.
