According to the reports, a container vessel APL Panama, stranded since Christmas Day off an Ensenada beach, now has its own jetty. Salvors commissioned the 500-ft. rock-and-sand ramp and hired a giant crane to carry containers ashore. The operation is the latest in a series of attempts to lighten the ship's load and get it floating again. Weighed down by cargo and pinned in by sand, the 880-ft. The ship was on a trans-Pacific route, and its cargo included electronic components for Baja California manufacturing plants as well as parts for car factories in central Mexico. The delay in delivery prompted Nissan, the Japanese car manufacturer, to stop producing vehicles for three days last week at its Aguascalientes facility.
