A man from Somerset and another from Devon are preparing to spend Christmas Day on a boat along with two others.
The Atlantic Mavericks - as they call themselves - are taking part in this year's Talisker Whisky Atlantic Challenge.
It is a 3,000 mile row from La Gomera in the Canaries to the finish in Antigua - lasting 45 - 50 days and starting on December 12.
During the trip they will row for two hours and rest for two hours.
Richard Baker, from near Chard, said: "We are raising funds for the Royal British Legion, Myeloma UK, Riding for the Disabled and 353 a charity set up by friends of ours in memory of their son who was the 353rd British Soldier to be killed in Afghanistan."
