I understand from reliable sources that Admiral Sir Jonathon wants to see a return to block drafting. For those of you who were not in the Navy when that was around, it essentially means that when a ship comes out for RTP the entire ships company join and take the ship through the tiers of training until it depoys. The ship then goes off to whereever and 6-9 months later an entirely new Ship's company join. The first crew go home and they then join another ship. Ot worked quite well when I first joined up but in those days we had dockyards all over the globe...may take a bit more planning nowadays
