"I didn't see in the story if their boat was salvaged or just abandoned either."

From the Daily Mail article:

‘The most poignant thing though was the fact that we had to let go of Sara. There was nothing to do but abandon her to the sea. We left a note aboard for anyone who finds her.

‘It would have been impossible for it to be towed all the way across the Atlantic so we both said a very tearful goodbye to her.

‘It had been our home for eight years and although we have now lost her, at least we still have our lives.’
