A longtail boat is a traditional watercraft commonly found in Southeast Asia, particularly in countries like Thailand and Laos. It features a distinctive long propeller shaft that extends from the back, allowing the engine to be mounted high above the water. This design enables the boat to navigate shallow waters and rivers, making it ideal for both fishing and transportation. These boats are often made from wood and can vary in size, accommodating anywhere from a few passengers to larger groups. Longtail boats are frequently used for tourism, offering scenic tours of coastal areas and islands, as well as for local fishing activities.
