Boats traversing the Panama Canal look strange and out of place, like mirages or optical illusions. That’s because the Canal — especially at places like the Culebra Cut — goes right through what would otherwise be continuous land. The Canal is, in essence, a trench. It was dug right across the width of Panama in order to connect two oceans: Pacific and Atlantic. Ships going through the Panama Canal, therefore, are strange-goers, undertaking a journey that would be fantastical but for feats of engineering that still boggle the mind.
