Boats on the Thames

When you are in Central London along the Thames River, it's difficult to remember that the Thames is subject to a lot of tidal effect. The boat in the foreground is a Hobie Cat, a popular one-design sailboat. The other boats are more typical of those that you expect to see along the river. The larger boats appeared to be live-aboard boats that float when the Thames is at its highest and sit on the mud the rest of the time.
