Boat towables, also known as water tubes or towable tubes, are inflatable devices that can be towed behind a boat for recreational activities such as tubing, wakeboarding, and waterskiing. They typically consist of an inflatable tube, often in the shape of a donut, that one or more people can sit or lie on while being pulled behind the boat. Some towables are designed for one person, while others can accommodate multiple riders. They can be made of durable materials such as heavy-duty PVC and come in various shapes, sizes and styles. Some towables have additional features such as built-in handles, multiple air chambers, or even built-in speakers. Towing a tube behind a boat can be a fun and exciting way to enjoy the water, but it's important to always follow safety guidelines and use appropriate equipment such as life jackets or personal flotation devices (PFDs).
