Hi I presume this vessel is on the Jackson Reef and most likely is the Lara. Originally delivered from Kieler Howaldtswerke late 1956 to Norwegian Shipowner Oivind Lorentzen, Oslo, with the name "Nopal Trader" and sailed under Norwegian flag 1956-74 in the company's Northern Pan-America Line (Nopal Line) between US Gulf ports and Venezuela-Brazil-Uruguay-Argentina. A roundtrip from New Orleans to Buenos Aires and back took approx. 2 months. Midship were accomodations for 12 passengers. The line was operated by 5 ships of similar size and type. Due to increasing flag discrimination and rising costs of operation of this type of vessels under Norwegian flag, the 5 ships were sold to foreign owners in the period 1974-77, and the line finally closed down 1979.
