After the first year of my hitchhiking world tour in South America, I arrive in Cartagena ( Colombia ). I am looking for a sailboat to reach Central America . The rainforest between Colombia and Panama is controlled by drug traffickers, so it is not possible to cross it. A blog follower-traveler puts me in contact with two Italian sailors in Cartagena. They organize cruises between the two countries, with a passage through the San Blas Islands and agree to take me for free (I just have to pay for my food). In exchange, I clean and cook for ten people for five days on board.
