Uniformed service students from the College of West Anglia Wisbech campus took on the Royal Navy swimming test, at the Hudson leisure centre.
The event raised £125 for The Fire Fighters charity, which supports members of the fire and rescue community.
Of the 22 students who volunteered to undergo the formalised test, 20 successfully completed the assessment.
To pass the swimming test, you are required to jump into deep water wearing overalls, tread water for two minutes, then swim 50 metres and climb out at the deep end.
Physical assessments for the students, is an important part of entry requirements into any of the uniformed services, so health and fitness education are embedded throughout their course.
“This is literally a pass or fail assessment or to put it another way a sink or swim,” said CWA tutor Adrian Kent, who organised the event with fellow tutor John Yare.
They thanked the Hudson Leisure centre management and staff for their continued help and support.
The test simulates a Royal Navy person jumping off a ship into the sea from a damaged boat, fully clothed without a life preserver. The candidate must then tread water for two minutes waiting to be picked up by a life raft. They must then swim 50 metres away to an awaiting life raft where the candidate must extract themselves into the boat to pass the test.
“The event has been of great value to me and given me a really good insight into the Navy physical tests” said Jacob Troughton (20), from Wisbech St Mary, who wants to join the Navy on completion of his course at CWA.
All successful candidates were awarded a certificate for recognition of their achievement.
