With the rough seas far too choppy for boats to move in close to the rocky island beneath the lighthouse, the only option is to zip back and forth via a rope thrown from the tower secured to the vessel.
That's one job that's definitely not for the faint-hearted!
More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.
Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.
So you can see why we need to ask for your help.
If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.
