A band of modern-day adventurers are to re-enact Shackleton's historic Antarctic expedition to mark its centenary. In an effort to recreate the original as closely as possible, the new expedition will limit itself to the technology of 1916.
They will set sail in a newlay launched replica of the wooden whaler, the James Caird, which was used by Shackleton's expedition. Alexandra Shackleton, Shackleton's granddaughter, will launch the boat at a traditional naval naming ceremony at Portland Marina later.
