Traveling as a passenger on a cargo ship (freighter travel) is a niche market in 2026, primarily served by specialized agencies like Slowtravel Experience or Cargo Ship Voyages. Major shipping lines like CMA CGM and Grimaldi Lines are among the few that offer cabins to paying passengers on specific transoceanic routes. These ships usually accommodate only 5 to 12 passengers, which allows them to bypass certain regulations required for larger passenger vessels. There are no "entertainment" staff or buffets; you eat with the officers and have access to a small lounge or gym. Common routes include Europe to South America or the US East Coast to the Mediterranean. It is a slow, meditative way to travel, but in 2026, it requires significant lead time—often booking 6 to 12 months in advance—and flexibility, as port schedules can change at the last minute due to cargo priorities.
