30 volunteers took part in a sponsored abseil, to raise £3,000 for Sheffield Sea and Royal Marine Cadets.
The abseil took place at Millers Dale Bridge in Derbyshire recently as part of a big summer collection for the maritime youth charity.
Royal Marine Cadet Lance Corporal Lawrence Carr, aged 16, of Stocksbridge High School, said: “Even though the weather tried to stop us, all those who participated did so with the utmost optimism and cheerfulness.
“The abseil was a fun, unique way of raising money and also allowing those who took part to experience yet another amazing opportunity provided by the adult volunteers.
“The money we raised will go straight to the renovation and maintenance of our new unit, providing more brilliant opportunities for the young people of Sheffield.”
Princes Trust volunteer and Royal Marine Cadet instructor John Daley added: “It was such an inspiration to see all these young volunteers come together and face their fears to raise money for our unit.
“There were a few tears to begin with but everyone pulled together and abseiled in the end.”
Sheffield Sea and Royal Marine Cadets is part of a natiowide network of 600 Sea Cadet units which has been giving young people training, skills and experiences on a naval theme since since it was established in 1854.
The charity is currently looking to recruit adult volunteers to help it grow its local units and provide a bigger service to more young people. No prior training is required.
