S297 was Smit-Lloyd’s original livery, later replaced by the group’s linked-chain S151 scheme.
Smit-Lloyd was formed in 1965 jointly with Holland America Lijn; the other founder is left unidentified in the source. Its operations included a Malaysian subsidiary and ventures with Loucas Matsas and N. Cotzias in Greece from 1979, and with Ultragas in Chile from 1989. It also managed vessels for Koninklijke Rotterdamsche Lloyd and Nederland.
