The Jankovich Company (formerly Jankovich & Sons) of San Pedro California, began as a launch company but more recently has specialized only in fuel services. None of their vessels had a stack until the former supply boat ROBYN J (US ON 637597) was re-engined and received the kind of stacks she could never have had in the Oilfield. Now she is used to tow bunker barges, and is seen here after delivering a bunker barge from Los Angeles to a thirsty cruise ship in San Diego.
