A Gaelic television and radio presenter aims to become the first person to row solo from New York to Stornoway on Lewis.
Niall Iain Macdonald rowed from Lewis, across the Minch, to Ullapool on the Scottish mainland in 2008.
He plans to set out from New York in May 2011 and reach his home town at the beginning of September.
If successful, Mr Macdonald would be the first person to use Stornoway as a destination for the Atlantic crossing.
Celtic rock band Runrig are promoting his venture which will raise money for the Scottish Association for Mental Health.
Mr Macdonald, who has faced personal mental health problems in the past, said: "The two years before the Minch row were the darkest and toughest of my life.
"They made me look at my life in a very different way, and now I try and make the most of each day.
"I want to use this challenge to highlight mental health issues in general and hopefully get people to talk more openly about them."
