The Sea Cadets use a nautical theme, based on the customs of the Royal Navy, to teach skills from cookery to computers, engineering, first aid, sailing, navigation and the art of seamanship both on land and on the water. Today, 14,000 young people based in 400 units in towns, cities and ports across the UK are challenging themselves and developing new skills supported by 9,000 volunteers. From rock climbing to shooting, there are so many challenging and exciting opportunities waiting.
