A LONGER LINE FOR MATSON'S LURLINE — The trailership Lurline is undergoing conversion at Sun Ship, Inc. shipyard in Chester, Pa., to a combination roll-on/roll-off trailership and lift-on/lift-off container carrier. The 700-foot Matson Navigation Company vessel will be lengthened to 826.5 feet by insertion of a 126.5-foot midbody section. Capacity will be increased from 434 twenty-four foot units to 1,046 units, auto space from 139 to 179, and refrigerated units from 100 to 204. The new 'ro/lo' carrier will reenter West Coast-Hawaii service early in 1982, Matson's centennial year.
