As a non-WAFU, QWI is not open to me, however I am curious (from a RN sense), how the process of creating a 'QWI' came about. At the moment we have Surface Warfare Instructors who either turn up and cuff it - on the basis of them being 'good eggs' - or want a quiet life in Portsmouth and don't mind the effective career foul for 3 - 4 years.
