A Greystones County Wicklow-based challenge to row from Ireland to Iceland next Spring made a preliminary call into Dun Laoghaire Harbour last week.
Led by James Murray, the expedition aims to "safely get from Ireland to Iceland under human power alone. No motors, no sails".
The schedule is to set off from Dublin, Ireland in Spring 2021 and for different crew members to join for legs on the way to Iceland.
As Murray explains on his website, row to iceland.com, "each team member has their own reasons for joining, but we all share an appreciation for the beauty of the places in-between and that seemingly extraordinary thing are possible".
Departing Dublin in April, the 3000km route will follow up Ireland's east coast before crossing to Scotland.
Following the Scottish coast, the plan is for the rowing boat to stop into fjords and towns along the way.
The plan then is to cross to the Orkney Islands and Shetland Islands before preparing for the big push to the Faroe Islands and then Iceland.
The trip is expected to take three to six months
Murray also asks on the campaign website that if you have experience with part of this route "we'd love to hear from you to help inform our plans".
