A makeshift boat of logs is commonly referred to as a "log raft." These rafts are constructed by lashing together logs to create a floating platform, often used for transportation or fishing. In some cultures, they are also known as "bamboo rafts" if made with bamboo instead of logs. Such rafts have been utilized by various civilizations throughout history for their simplicity and effectiveness in navigating waterways.
