There may be a language issue here, rather than a vocabulary issue. Even if he uses English for emergency communications, it's likely that he uses Italian for ordinary discussions of ship performance. "Tilting" may be a case of not knowing the English word for a nautical concept that he probably would have described correctly in his native language.
No - I’ve worked with Philipinos, Koreans, Japanese, Chinese, Arabs, Aussies, and Thai - all of them would have said listing. English is the common language of OCEAN going vessels just like in the world of finance.
That being said - if I had been the PA - I’d have quit wasting my time after the first go round, sent a pilot onboard to lead the evacuation, and a harbor police to arrest the captain after his first delay in reboarding.
Absolutely no sense in this - every officer on the bridge - CO, OOD (or civilian equivalent), and Navigator should be charged and jailed. The others are duty bound to turn the bridge over to the CO and log their complaint if they feel he is putting the ship in harms way for no good reason. I saw something where the navigator may have protested and logged same, but haven’t seen follow up.
Any ships crew that was off the ship prior to the last passenger should be up for charges as well. The CO likely had a license that was “paid for” and not earned.
