In 2020, Christiaan De Beukelaer spent 150 days covering 14,000 nautical miles aboard the schooner Avontuur, a hundred-year-old sailing vessel that transports cargo across the Atlantic Ocean. Embarking in Santa Cruz de Tenerife, he wanted to understand the realities of a little-known alternative to the shipping industry on which our global economy relies, and which contributes more carbon emissions than aviation. What started as a three-week stint of fieldwork aboard the ship turned into a five-month journey, as the COVID-19 pandemic forced all borders shut while crossing the ocean, preventing the crew from stepping ashore for months on end.
