The common term for the large, flat-bottomed boat used for fishing in shallow waters is "skiff." Skiffs are typically small, lightweight boats designed to navigate in calm, shallow waters efficiently. They are often used for inshore fishing, recreational activities, and transporting goods. With their flat bottoms, skiffs can easily maneuver in areas where deeper boats cannot access, such as estuaries, marshes, or tidal flats. The design of skiffs allows for stability and ease of use, making them popular among both amateur and professional fishermen. These boats come in various sizes and can be powered by oars, motors, or sails.
