👉 Bathyscaphe is a type of boat, typically used for deep-sea exploration and research. It has a long hull with two large sails to help it sail through the water. The name "bathyscaphe" comes from the Greek word "baths", which means "water," and "scaphus," which means "hook." This boat was historically used by ancient Greeks for deep-sea exploration, but today it is also used in scientific research and tourism.
