I’ve had the thought that I would like to go across the Atlantic on a ship some time. Figured if it were ever to happen, it would likely be on a large cargo vessel that took aboard some paying passengers. Well, there is a cargo ship that will take aboard paying passengers, the only twist being that it is a sailing ship. A 32 meter long brigantine, the “Tres Hombres” to be precise. It maintains a freight service between Europe, the Caribbean and America. Besides a cargo capacity of 35 tons, she has accommodation for 5 crew members and a maximum of 12 passengers. Not necessarily cheap, but then I suspect the economics of shipping cargo this way isn’t quite what a Panamax offers, not to mention the cost of getting this vessel seaworthy and then maintaining that status.
