The Swillies

An evening walk along the Belgian Promenade and under the Menai Bridge gave us a close up view of the currents that flow back and forth along the Menai Straits according to the tide. Their speed and unpredictability has long been recognized as a navigation challenge - "In that arm of the see that departeth between this island Mon and North Wales is a swelowe that draweth to schippes that seileth and sweloweth hem yn, as doth Scylla and Charybdis - therefore we may nouzt seile by this swalowe but slily at the full see."
