Highbury's Prince's Trust team took on the armed forces in the Royal Navy Junior Leaders Field Gun Competition.
Crews of young people aged 16-25, raced to dismantle, move, reassemble and fire the guns in the shortest time possible.
The competition day took place on Collingwood Open Day, where the gun runs were viewed by several hundred spectators including team members' friends and families.
The crews, representing the forces and civilian organisations, including the Princes Trust, local schools and colleges, went to HMS Collingwood in Fareham to experience this great naval tradition.
To succeed the teams need to work together with determination and discipline as their team-working and problem-solving skills are put to the test.
Two teams from Highbury College and one from Bognor combined this year to field two crews. They then spent four days training under the direction of the Royal Navy in order to reach the standard required to compete on the day.
The opportunity to compete in this competition is unique to the Prince's Trust teams in the South East. Sharon Carroll, Team leader of Highbury College's Prince's Trust team, commented: "It was an extremely tiring week but all team members thoroughly enjoyed it and every single one of them demonstrated enormous effort and commitment throughout the week."
Martin Brown from Team 80 said: "I really enjoyed the week, it was hard work!"
Whilst not making it to the final, the Prince’s Trust crews performed extremely well with a personal best – despite one wheel falling off half way through one of the runs!
