This is Kai on the Thames below Tower Bridge, sailing up river, back to where she started at Pimlico Pier and Westminster Boating Base.
Sunday mornings, blue sky, gentle breeze, tacking and gybing backwards and forwards, avoiding tourist boats, fighting the tide, trying not to be dunked by the better sailors. Usually the kids playing pirates are fearless and just love any opportunity to capsize. Occasionally being allowed down river as we were last month, memorably to sail under Tower Bridge and the Olympic Rings.
