Abstract

A four-chamber inflatable kayak comprises an upper chamber, a lower chamber, connecting portions as well as two side chambers and two side coverings. The upper chamber and the lower chamber are streamlined with a wide center and narrow ends, and the outer portion of the two ends of the upper chamber and the lower chamber is connected to each other by means of a connecting portion. The connecting portion has two separate compartments that are separated from each other. Both ends of the upper chamber and the lower chamber are accommodated in the separate compartments in the connecting portion, so that a cavity with accommodating space is formed between the upper chamber and the lower chamber. The upper chamber comprises a cockpit hole disposed in the middle. The cockpit hole is communicated with the cavity.
