The Lord Nelson's voyage around the world was designed to take her the right way around the world, dodging the worst of the weather, and following traditional sailing routes.
But there was no avoiding the notorious Southern Ocean, acknowledged to be the sailing equivalent of climbing Mount Everest.
On board, the ship's navigator Marcin Dobrowolski turned cameraman and filmed the epic passage which took the ship around Cape Horn and then further south to Antarctica.
Richard Jones has been following the story of the ship since she left the UK, and used Marcin's pictures for this special report on the Lord Nelson's biggest challenge.
The tall ship Lord Nelson is a familiar sight around the coast of Britain. She was the first ship of her kind specially designed for able-bodied and disabled people to sail side by side.
Now she's undertaking her biggest ever challenge - a two year, 50,000 mile voyage around the world visiting 30 countries on all seven continents.
For a series of special features this week, Richard Jones has been in South Africa catching up with the ship and her crew.
He meets crew members James Whale and Kyle Baker, Mike Drummond Smith from Care for Casualties, and Chris Phillips, Captain of the Lord Nelson.
Next week we run a series of special reports from South Africa. Our reporter Richard Jones went on board the tall ship Lord Nelson as she makes her maiden voyage around the world. The Jubilee Sailing Trust enables able-bodied and disabled people to sail a tall ship side by side.
