Shipping is overwhelmingly made up of men, but not because women are disinterested or dissuaded from it, according to Anna Silva, who has been working in the industry for two decades.

Most women are simply unaware of it as a career, said Silva, who started out in shipping in 2000 as a teacher at State University of New York Maritime College and is now co-president of the Florida chapter of the Women’s International Shipping & Trading Association.

“I honestly think it’s a best-kept secret,” she told TradeWinds.
