Five years on and 57 people celebrated the world record by riding the attraction in the buff, raising more than £10,000 for Southend Hospital Charitable Foundation’s Keyhole Cancer Appeal.
They travelled from all over the UK, including Edinburgh, Newcastle and Swindon, to take part in the challenge.
Adventure Island operations director Andrew Renton said: “It’s been an absolutely superb day with people all enjoying the chance to do something memorable, good fun and raise a large amount of money for a fantastic, local charity.
“We’ve heard some amazing stories from so many who have been directly, or indirectly, affected by cancer and wanted to give something back.
Lucy Thomas-Clayton, from Southend Hospital Charitable Foundation, said: “It takes a lot of nerve to take off all your clothes in front of complete strangers, plus the world’s media.
“We would like to say a massive thank you to everyone who was brave enough to bare all and raise such a huge amount of cash for our vitally important cause.
