 Princess's third charter ship was none other than Costa's "Carla C".Originally, Compagnie Générale Transatlantique's SS "Flandre", the ship had been purchased by Costa in the late 1960s and given a major rebuilding.Almost immediately after completion, the ship was chartered to Princess, and it was on board the ship, which was marketed as, but again not officially renamed, "Princess Carla", that Jeraldine Saunders wrote the first chapters of her nonfiction book "The Love Boats."
