to activate the docking system as will be described later in greater detail herein the controller supplies power to the electromagnetic generators 106 coupled to the dock 102 the electromagnetic generators 106 produce a magnetic field that attracts the magnetic device 108 coupled to the watercraft 104 the magnetic device 108 and watercraft 104 are pulled towards the dock 102 the controller may regulate the magnetic field produced by the magnetic device 108 for example as the watercraft 104 approaches the dock 102 the electromagnetic generator 106 or the magnetic device 108 may reduce the strength of the field to reduce the impact of the watercraft 104 from hitting the dock 102 additional proximity sensors may be used to allow the controller to determine distances of separation between the watercraft 104 and the dock 102 the controller may then adjust the strength of the magnetic field or reverse the polarity based on the proximity of the watercraft 104 once the watercraft 104 reaches the dock 102 the electromagnetic generators 106 may maintain the magnetic field to maintain the watercraft 39 s position the watercraft 104 may also be coupled to the dock 102 using convention mechanical couplings for example ropes elastic.
