It's a boggy December morning on the Cleddau river and Alun Lewis is tending to his four miniature horses and a few boats moored up on his four acres of land. We're in the quiet hamlet of Landshipping that looks out onto the large expanse of water which is otherwise only 50 or so feet wide at other times of the year. It is prime time for Alun – one of the world’s last six compass net fishers – to don his waders and float his little handmade 150-year-old wooden boat towards the estuary.
