An 18-year-old braved the elements to spend three weeks sailing with a charity.

Kristina Cartwright-Riley, of Potters Bar, took part in the Ellen MacArthur Cancer Trust graduate volunteer training last month.

Along with 13 others, she braved the weather on the Solent to complete the RYA Competent Crew Course and find out what it takes to be a volunteer with the charity.

She will return to volunteer on trips over the summer.

Kristina first sailed with the trust after she finished treatment at the University College London Hospital in April 2009 for acute lymphoblastic leukaemia.

She said: "The trust has given me so much confidence. I want to be able to help give other young people that opportunity to make new friends and rebuild their confidence."
