The Fastnet Rock

Fastnet Rock is one of the most iconic maritime landmarks in the world. The present lighthouse is the tallest and widest anywhere in Ireland or Britain. It is about as rugged as they come. Its Irish name, An Charraig Aonair, means “The Rock that Stands Alone”. (history)

The tide rises 12 feet and currents round the rock at spring tides can attain a force of 3 knots. It is a very rare occurrence for the water to be sufficiently smooth to enable people to step out onto the rock, averaging about 12 tides a year.
