A magnetic connection system with at least three components for connecting host and target systems. A first magnetic connector is attached to the host system, a second magnetic connector is attached to the target system; a third magnetic connector or puck is positioned between the first connector and the second connector. The first, second, and third connectors fit together with their magnets aligned, and the magnetic attraction is stronger between the puck and the target system connector than the puck and the host system connector. The system can transfer fuel, data, or electricity. In one example, the system transfers fuel from a fuel supply vessel to a target vessel with minimal human effort to attach the fuel connector components. The puck can have a conduit for fuel, data, or electricity that is centrally aligned with a receiving conduit in the target system connector.
