Alan, yes the re-titled uni of Plymouth is still sending out marine people to take over every part of the industry, at sea or the office, on yachts and tankers. I did Maritime biz + law and stumbled into a job in shipping.
On the side lines, back then when I was a lad, I understand that the uni had the largest number of powerboat instructors in one establshment (easily over 18).
Those were the days when you could test the design limit of the boats and of course, those that taught us had never heard of red tape and rules. A bit different now!!!
Unfortunately there are only about 6 of these actively earning the ticket, all of them part-time and most run regatta safety for events. some of the others are active, but no ticket anymore.
