The Geo Quiz follows a unique catamaran on a slow trip around the globe this time. One of the catamaran's stopovers was in Southeast Asia, in a nation of more than 7,000 islands. This nation lies east of Vietnam and was named after Crown Prince Philip II of Spain.
Now, about that catamaran: it's attempting to circumnavigate the globe relying on solar power. It's going to take a while, as this catamaran's average speed is a whopping six miles an hour. So you have plenty of time to name that large Southeast Asian archipelago where the vessel stopped recently.
Reporter Simone Orendain took a tour of the world's largest solar-powered boat when it docked temporarily in Manila in the Philippines, the answer to our quiz. The catamaran "Turanor" is now on its way to Singapore.
