Described is a coupling device for a joining together adjacent dock segments of a dock installation including an elongate pin portion and at least one clamp portion, each positionable on respective dock segments. The pin portion has at least one elongate first clamp surface aligned along its length with a central longitudinal first axis, the pin portion being configured to be received in a corresponding pin-receiving region adjacent the clamp portion. The pin-receiving region is at least partially bordered by at least one second clamp surface which is aligned with a second axis. The clamp portion is configured to be actuated between an open pin-receiving configuration, at least partially opening the pin-receiving region along the second axis, and a pin-engaging configuration with the first clamp surface engaged with the second clamp surface. The second axis is configured to be substantially parallel with the first axis, and with a lateral axis of at least one of the dock segments, for securing the pin portion therewith, so that the pin portion is rotatable relative to the clamp portion about the first axis to accommodate relative movement between the adjacent dock segments.

Described are various embodiments for coupling devices for dock installations.

An inflatable watercraft for supporting a user on water includes a flexible water-proof and air-tight bladder having a first end, an opposing second end, a top side, a bottom side, and two opposing lateral sides. The first end is substantially open to expose an interior surface of the bladder and an interior volume of the bladder. A first seal is fixed with the interior surface of the bladder proximate the open first end of the bladder. As such, to inflate the watercraft the user holds the first seal open while scooping air into the bladder until the bladder achieves a substantially inflated configuration. The user then places the first seal in the closed configuration to prevent air from escaping the bladder. Additional seals and means for inhibiting air leaking from the bladder are provided. Multiple forms of watercraft are contemplated.

An inflatable water-based motorised device docking station is described. The inflatable water-based motorised device docking station includes an inflatable tube configurable to form an open ended area to receive a water-based motorised device; a floor area coupled to a portion of the inflatable tube; and a ballast bag with dump attached to the floor area and configured to stabilise the inflatable water-based motorised device docking station.

A self-deploying float assembly to support mechanical equipment such as aerators and mixers for use in water, wastewater and process water stream treatment basins and a method of installing same.
