A buoyant offshore platform for supporting a renewable energy system having a base portion for submerging below the surface of a body of water, a top portion, at least one mooring line for fixing the platform to a bed of the body of water, and a tensioning means for applying tension to at least one of the mooring lines. The platform further comprises a floating configuration in which the platform is positioned floating on the surface of the body of water. The platform has a deployed configuration in which the base portion is submerged and the top portion remains above the surface of the body of water. In use, the tensioning means is arranged to apply tension to the at least one mooring line fixed between the platform and the bed such that the buoyant offshore platform transitions between the floating configuration and the deployed configuration.

The embodiments herein provide a tool for assisting users while docking a boat. According to an embodiment herein, a boarding aid mechanism for a boat for assisting a passenger while docking a boat includes a clamp, a vertical slide arm and a dock arm. The clamp is secured to one side of the boat. The vertical slide arm is mechanically coupled to the clamp using a pin. The vertical slide arm comprises a rubber handgrip for supporting and balancing the passenger. The dock arm is an L shaped structure extending from the vertical slide arm. The dock arm is slid into the vertical slide arm and further the vertical slide arm is secured to the clamp.
