Kieran and Shaun Sweeney were forced to put in an SOS call when the rudder of their home-made pedalo broke a day after they set off from Gran Canaria aiming for Port St Charles in Barbados.
The Cumbrian duo decided to make the trip to raise £50,000 for a children's heart unit at the Freeman Hospital in Newcastle. Their preparations started last summer, with the pair packing enough provisions on board to supply them with the 8,000 daily calories they each needed for the 30 to 35 day crossing.
They decided to make the journey naked in order to avoid painful chafing from the salt water aboard their 22ft craft, the Lydia Rose, named after the daughter of a friend who died tragically from heart problems despite the care received at the Freeman Hospital.
It's not the first false start the Sweeneys have suffered: they set off in December, making it just 14 miles before being forced to turn back because of a faulty drive-shaft.
So let's hope the brothers won't let the latest setback put them off - you can follow their progress, see more about their boat and make a donation at their website.
