GENOA — Cristina did it to escape after a tough breakup. Luigi because he dreamed of adventures and the South Seas. Marianna embarked just “before the refrigerator factory where I worked went out of business. I’m one of the few who got severance pay.”

To hear their stories, you have to go to the canteen on Via Albertazzi, in Italy's northern port city of Genoa, across from the ferry terminal. The place has excellent minestrone soup and is decorated with models of the ships that have made the port’s history.

There are 38,000 Italian professional sailors, many of whom work here in Genoa, a historic port of call that today is the country's second largest after Trieste on the east coast. Luciano Rotella of the trade union Italian Federation of Transport Workers says the official number of maritime workers is far lower than the reality, which contains a tangle of different laws, regulations, contracts and ethnicities — not to mention ancient remnants of harsh battles between shipowners and crews.

The result is that today it is not so easy to know how many people sail, nor their nationalities.

What is certain is that every six to seven months, the Italian mariner disembarks the ship and is dismissed: they take severance pay and after waits for the next call. Andrea has been sailing for more than 20 years: “When I started out, to those who told us we were earning good money, I replied that I had a precarious life: every landing was a dismissal.”
