Not so much shadows of the boathouse as a shadow on the boathouse. This building by the River Severn in Worcester is a modern structure faced in brick, timber and glass, the shape of which is clearly intended to reflect the forms of the rowing boats that it houses. None of its sharply pointed "prow" can be seen in this photograph: for that you'll need to look at the next post.
