Originally a clever adaptation of the inner tubes found in tires, the belly boat has evolved. Today’s version is usually a seat with an inflatable tube that curls around it in a ‘U’ shape, with the open end allowing the fly fisher easy access to the seat.
A retaining bar keeps you in place while your legs dangle down from the front of the seat, ready to provide the power by paddling with your feet. There's also electric versions that have a propeller so you don't have to paddle.
