South West students showed they were ship-shaped when they battled eight other colleges win the Naval Careers Service Challenge cup.
The 15 Royal Marine-sponsored Weston College public service students took on an assault course, tug-of-war and deck hockey on a naval ship.
They also tackled navigation, cross-country and mock grenade throwing over two days at the HMS Raleigh Piers Cellars Training Centre in Cornwall.
Senior public services lecturer Dave Beresford said: “The level two and three students were all under the age of 18 and really pulled together as a team.”
He added: “Weston College achieved fantastic results against well-motivated adversaries to win the competition out right. They did brilliantly.”
