Being at sea aboard huge luxury vessels is very glamorous. As a skipper-come-captain, it is easy to be wined and dined each evening by billionaires with the finest foods and drinks. The only drawback is that you steadily become an old soak. I worked alongside many captains who became just that.

Thinking back to a collision at night with JJ, the skipper, and a refugee boat – he had gotten drunk with a stewardess and gone to bed, leaving the vessel on autopilot. The similarities to the Titanic are on a much smaller scale but just as deadly. Doing double dog watch shifts doesn't help. Instead of 4 hours, you do 8, covering for someone or even the milk shift when you start at midnight and sometimes finish six hours later. Dozing off is so easy if the autopilot's on. Many of our crew used to come on the milk shift smelling of booze – sea watches disorientate you. I've seen quite a few old sailors having a beer for breakfast as they come off the first watch at 4 am.
