Tonight from BBC South
Saving Chichester Harbour: part 1 A solar-powered radio beacon leads vessels into one of the world's most beautiful harbours - and one of the best organised. Ten years ago it faced chaos from the conflicts of fishermen, naturalists and invading yachtsmen.
In the first of two films Martin Muncaster , aboard his family yacht Cottontail, explores 17 miles of water, and meets people who banded together to rescue the harbour from self-destruction.
