S4C viewers can follow the stormy adventure of a Bala woman through extreme weather conditions and dangers at sea as she competes in the famous Clipper Round of the World Yacht Race 11/12.
In the two-part series, Hwylio'r Byd, which starts on Tuesday, 15 May, we'll follow Elin Haf Davies as she prepares for one of the toughest races in the world where she'll spend 30 days at sea and travel over 6,000 miles.
This isn't the first time for Elin to battle against the elements. In 2007 she rowed across the Atlantic Ocean and she has raised over £250,000 for children's charities.
"I was 30 years old going out on the sea for the first time. The decision to row the Atlantic Ocean in 2008 came out of nowhere. I had no idea what to expect beforehand and after 77 days on the Atlantic I knew that having adventures at sea was the life for me," says Elin, who this time is raising money for the Noah's Ark Appeal, the official charity of the Children's Hospital of Wales.
The Clipper race started in Southampton back in August 2011. Since then, competitors have travelled across the world's greatest oceans and docked in South Africa, Australia, Singapore, New Zealand, Brazil and Madeira.
The race is divided into eight stages and Elin joined the team for the sixth stage - along the Pacific Ocean from Quingdao in China to San Francisco.
"The Pacific Ocean was very dangerous this time. For 30 days we had no blue sky, no sun, and giant waves threatened us constantly," says Elin.
"It's difficult to explain the greyness of such a situation. It's absolutely continuous between the sky and sea and it zaps your energy and your enthusiasm. It's amazing how a little sunshine can energise you."
S4C viewers were given a preview of the epic adventure in the short film Calon: Hwylio'r Byd at the beginning of March. But in the new series, we'll follow her precise preparations ahead of the biggest race of her life from China to the USA's West Coast. Production company Telesgop were given access to all areas on the wet and windy leg of the race which can be seen in the final episode.
Elin's feet are firmly back on dry land by now, but the race continues. Depending on the weather and other events, the entire Clipper race should come to an end back in Southampton on 31 July.
