On Spetses, My Greek Odyssey joins the festivities of the annual Spetses Classic Yacht Regatta, established to honor the boat builders of the island and the seafarers who fought in the 1821 Greek War of Independence. Peter then cruises to Hydra where all the houses are 200 years old, as no new buildings are permitted by law, and the only means of transport are mules, horses, and water taxis.
