The recent activation by TRANSCOM of 28 cargo ships, makes it a good time to take a look back at eight iconic shps from the 1970s still in service today.
When I was a young student of naval architecture at the University of Michigan in the early 70s, I attended a Society of Naval Architects and Marine Engineers (SNAME) convention in New York City. In our visit, we took a field trip across the river to the Sea-Land container terminal at Elizabeth, New Jersey to tour a new SL-7 class container ship.
The eight SL-7s were Malcom McLean‘s modern-day clipper ships. As I stood on the pier looking up at the ship, I remember finding the long hollow water line to be breathtaking. And whereas the clipper ship Sovereign of the Seas was just over 250′ long, the SL-7s were close to 1000′ overall. With steam turbines producing 120,000 HP, these ships could cross oceans at 33 knots. They would each carry over 1,000 containers, making them the largest container ships in the world at that time.
