Abstract:

One or more embodiments disclosed herein relate generally to flotation devices, and more specifically to modular flotation devices with a mechanism to removably attach to other modular devices. In one embodiments, an apparatus includes a first flotation module and a first connector coupled to the first flotation module. The first connector has a first end portion, a second end portion and a sidewall extended from the first end portion to the second end portion. The sidewall defines a plurality of circumferentially defined stepped portions configured to matingly engage a second connector of a second flotation module to couple the first flotation module to the second flotation module. The first connector is selectively operative as one of a female connector or a male connector with respect to the second connector.
