Why Marcion was identified as the 'naukleros' in the late second century

A sample of what appears in the Real Messiah order it here

If the reader accepts my understanding that the term naukleros derived from Plato the context must have been as follows. The various 'heretics' - Valentinus, Basilides - i.e. those who Clement identifies as having come after Marcion were all vying for control of Marcion's 'ship' as it were and send it in a new direction. The underlying of the contemporary period was - who gets control of Marcion's 'ship' - i.e. the Church - and what direction should they/it take in the new age.
