I remember 3 types of sea dinghy drill. The first was off Plymouth in a single sea life raft. No problems there. The second was being told to jump out of a Hastings into Limassol Bay. The last was in a MS24 (or whatever number it was) with the 20 or so VC10 crew, most of which were depositing their breakfast either over the side or in the life raft. Not nice. The final drill I did was in the Brize swimming pool when I was age of 55 and being told to swim 2 lengths with a flying suit on (which acted as a great sea anchor). Old Duffer, I also did the Mountbatten sea drill age 54 in February, but luckily was allowed to an immersion suit. Did they ever learn?
