Why different ships mattered to Doug Clarke

Did Doug Clarke have a favourite ship, and why?

His son remembers different attachments: Montrose for a family visit, Ark Royal for a carrier launch, and an Oberon-class submarine for his first time at sea in a submarine.

Alex Clarke does not identify one favourite ship for his father. Montrose mattered because Doug could take the family aboard. Ark Royal was associated with his first carrier launch, while the Oberon class recalled his first time at sea in a submarine. The Malaysian fisheries vessel brought a different attachment through the work he enjoyed. His Liverpool background also made the Mersey ferry project a particular source of pride.
