An inflatable stand-up paddle board (SUP) and a built-in inflation pump are provided. The inflation pump includes a pump body incorporated into a body of the SUP, an inflation assembly, and inflation and deflation valves in communication with an air chamber of the SUP. The body of the SUP includes first and second surfaces and a lateral confining band extending in a circumferential direction of the SUP and covering edges of the first and second surfaces. A mounting space may extend through the air chamber and the inflation pump may be mounted within the mounting space.

An inflatable standup paddleboard having a split deck pad. The split deck pad may allow for easier storage and greater customization options for the inflatable standup paddleboard. The split deck pad may also be removable from the body of the standup paddleboard through integral grooves within the body of the inflatable standup paddleboard. The structural integrity and buoyancy may be further improved with a crisscrossed structure of strings within the interior of the inflatable standup paddleboard.

The present disclosure features inflatable kayaks that have a non-planar hull bottom surface. The kayaks may include an inflatable, tubular body having a bow, a stern and a midsection, wherein opposed side tubes of the midsection define an open central seating area having a predetermined width when the tubular body is inflated; and a hull bottom fabric joined to a lower surface of the body outside of a periphery of the seating area, the hull bottom fabric having a width that is greater than the width of the central seating area such that the hull bottom fabric is not tensioned between the side tubes, and the hull bottom fabric being joined to the side tubes outboard of a vertical center line of the side tubes.

A portable inflatable diving float that includes an inflatable float body is revealed. The float body consists of a horizontal portion provided with a left folding area formed on the left side and a right folding area formed on the right side. After the left and the right folding area being folded to a middle portion of the float body, a left edge portion of the left folding area and a right edge portion of the right folding area are connected by a first connection member and kept in the folded state. A flat body formed after deflation of the float body becomes a backpack body with smaller area. At least one strap member is connected between the top end and the bottom end on a front side or a back side of the float body so that users can carry the backpack body on their back.
