Small white squares dot the ocean off Havana, an unlikely fleet of fishermen bobbing on makeshift polystyrene rafts they use to make up for a lack of fuel or money to buy a proper boat.
"In the past, we fished a lot with the inner tubes of truck tires, but the danger was that they would burst. With these rafts, there is no danger. They do not capsize," said Coli Rivera, 54, returning from several hours of fishing off the village of Santa Fe, near Havana.
