Doug:
You are correct in your statement about the move to the ocean freight containers. Prior to the use of ocean freight containers, ships carrying cargo were known as "break bulk carriers". These had cargo holds, and cargoes could take the form of crated goods, goods in paper cartons on pallets, or in sacks, bales, barrels, or on skids. Loading and unloading these cargoes fell to the longshoremen. In this same era, the break bulk type cargo ships docked along the North River (Hudson River) piers, some East River Piers, as well as the Brooklyn piers. It was common knowledge in that era, when I was a kid, that a lot of goods "fell out of the slings" and wound up being sold or given to people who either were related to longshoremen or through some intermediary parties. Around Christmas time, the pilferage was ramped up and included imported smoked hams, sewing machines, Italian leather coats, and anything else that might make a good Christmas gift. Whisky was shipped in cases, but some of this managed to make it off the piers as well. When someone suddenly had a new European made sewing machine or had a whole proscuitto (Italian hard smoked ham, usually sold by the quarter pound as it is quite pricey), if asked how they came by it, the answer might be something like: The guy down the street's brother-in-law works on the docks. Stuff falls out of the slings..."
I remember once at some gathering at a friend of the family's home, this line of conversation came up. I was a very literal kid of maybe 6 or so, and knew how loads were slung to be picked by cranes (having been on jobsites with my father). The answer about something falling out of a sling seemed fishy to me. I opened my mouth and asked: "Why wasn't the load rigged right ?". Mom kicked me under the table, and I asked her why she was kicking me. I then asked: "If the stuff fell out of the sling coming off the ship, why didn't it fall into the water or get smashed to bits landing on the pier ?" At this point, Mom was looking daggers at me and dragged me out of the room to tell me to shut up and not say another word, she'd explain later. On the drive home, my father said the NY Waterfront was "a very rough place where they do things differently and people can get into trouble really easily..."
As the story goes, in the 1950's or perhaps the early 1960's, the handwriting was on the wall for how ocean freight would be loaded and moved. When I was alittle guy, my parents would sometimes drive north on the old West Side Highway. This was an elevated roadway which paralleled the North River waterfront. Along the piers was a veritable world atlas of names of countries, and exotic sounding shipping lines such as "Congo Line", "Boma Line", and further upriver in the 40's and 50's were the piers where the big "name" liners docked. Riding along the West Side Highway, I'd occasionally see cargoes being handled in the nets, or as crated goods being picked off barges or lighters (self propelled barges with stiff leg derricks for handling cargoes). The Brooklyn piers handled the German shipping traffic (Lloyd and Hamburg-American), Istbrandsen/American Export Lines, Moore-McCormack Lines, Gran Columbia Lines, and plenty more. Those are the shipping lines which come to mind at this point. The Brooklyn piers were always interesting as you'd see trucks in the forms of cabs and chassis being loaded aboard ships for export, heavy equipment, and plenty of large crates. You'd also see the traditional net cargo slings and skidded loads being hoisted on or off of the ships.
Back in those days, in the 1950's-early 1960's, the Port of New York was a really busy place and a lot of cargo moved through it. The names of the ships and the ports or registry (if visible depending on how a ship was docked) all used to seem so exotic to me, and made what we studied in social studies as well as the old roll-down maps in our classrooms, come alive. I'd see the roll down maps of the world in my classrooms and see the dotted lines crossing the oceans of the world, giving the shipping routes and mileages and think of the ships tied up at the Brooklyn piers. As a kid, I entertained notions of becoming a merchant marine engineer and seeing something of the world in that way. Seeing the ships at the Brooklyn piers without knowing the real story of what went on aboard the ships as well as on the piers was back when I was an innocent kid and not wise to too much. That soon changed as I got into my adolescent years and got a grasp on the real world.
In that same era, ccean freight containers were on the horizon. At that same time, the North River piers were in sorry shape. The agency within NYC government which had responsibility for the piers had a decision to make. As it were, the North River Piers were seeing less of the kind of traffic they had handled. A lot of traffic on the North River piers was from railroad car floats, which brought freight cars into Manhattan. A number of these cars contained livestock to be slaughtered in the meat packing plants on the West Side of Manhattan. This traffic was all but gone with the move to frozen carcasses moved by reefer trucks. The move to jet aircraft had pretty well killed the passenger liners docking there as well. All that was left was some break bulk cargo shipping. This is when the NYC agency had to make a decision: build new piers for break-bulk ships, or build piers with cranes and facilities for handling containers. The NYC government agency opted for piers to handle break bulk ships. In a very short time, these piers were totally un-used. Across the harbor in Newark and Elizabeth, New Jersey, the new piers and with special cranes and land facilities for handling thousands of containers were built. All the cargo traffic in the Port of NY went to the New Jersey side of the port. Belatedly, a few Brooklyn piers were rebuilt to handle containers, but nothing like what was developed in Elizabeth and Newark.
Of course, with the move to ocean freight containers, the next step up in theft was to divert whole containers. Instead of longshoremen making off with some of a load, the whole load would be diverted and stolen. I remember working on a nuclear powerplant job (Millstone Unit II) in Connecticut in 1973-75 for Bechtel. That jobsite was wide open with all sorts of rackets and shady dealings going on. You could play the numbers, play the horses, get into sports betting (no legal off track betting or legal numbers lotteries existed then). If you wanted something, you put the word out and someone might just get the word it was available at a very attractive price. I remember one guy, around this time of year, was walking around wearing an Irish Fisherman's Sweater. He was taking orders as a "shipment had come in". Italian leather coats and shoes, handbags, Solingen carving sets, and all sorts of handy gift items seemed to be available on the jobsite for very low prices. You knew if you were going to buy any of it, you were buying stolen goods, and you also knew never to ask where or how it came to pass that those goods were for sale for so low a price.
Getting back to the Brooklyn waterfront: A millwright I worked with in 1981-83 told me that in the 1950's, he had been working on a job in a NY Department of Sanitation garbage incineration plant on Hamilton Avenue. This is right on the Brooklyn Waterfront. One morning, when he arrived to go to work, he saw a crowd of longshoremen outside the nearby entrance to a pier. This was normal for shapeups when ships would need to be loaded or unloaded. As the millwright told it, he sensed there was something wrong, and sensed some real trouble was going to bust loose. He decided to stay in his car and wait a bit rather than pass through the crowd of longshoremen. As he waited, he said a scene that will stay with him for the rest of his days occurred. He said a "gloved hand holding a baling hook" seemed to loom large over the crowd, and plunged downward. Just that quick, the crowd melted away, as if they flowed down the storm drains. The only one left was a man bleeding out on the sidewalk with the baling hook in his chest. The millwright knew if he was seen and thought to have seen anything, he'd likely be the next casualty. He said he got on the floor of his car and stayed there until after the cops and meat wagon were gone from the scene. He said he never heard a word about the murder, not that he'd be crazy enough to ask about it.
My father was a construction inspector for the NYC Department of Buildings, and got around Brooklyn pretty well. Dad was extremely street wise, having grown up in a rough neighborhood and been around all sorts of people. Dad always told me how there were entirely different rules on the waterfront, and things had a way of happening. I remember Dad telling me of how a barge mounted crane suddenly sank over a weekend, telling me that the contractor with the crane apparently did not "play ball" with the boys who ran things on the waterfront. One time, Dad came home with a longshoreman's baling hook. It hangs in my shop to this day. It is a good deal bigger than a hay hook, and forged of good steel.Dad claimed it came off the piers along Hamilton Avenue.
I think with bar coding, computers, and ocean freight containers, the amount of theft is greatly diminished when the overall numbers are considered. However, if a container is diverted and the contents stolen, it is a single haul bigger than anything the longshoremen in the break-bulk days could have pulled off. At the same time, the gross tonnage of the ships carrying cargoes has also risen almost exponentially. Where a break-bulk ship might be 300 or 400 feet long and hold perhaps 15,000 tons of cargo, the new container ships are at least twice as long, many times the gross tonnage, and hold well over 1000 containers. One container diverted and stolen seems like a lot when considered by itself, but as a percentage against the total cargo, becomes fairly small. With todays sophisticated hackers, a container with valuable contents can be spotted, and arrangements made to divert it once it is loaded onto a semi trailer and moved out of the port. It is a whole different world. Longshoremen still work on the docks and run the container handling cranes and other machinery and "work cargo", but nowhere near the numbers they once did. I think theft of cargoes in ocean freight containers had moved from the longshoremen to other people altogether. It's a combination of cybercrime and sending a tractor driven by someone who is part of the theft rather than something like an overt hijacking of a rig. Today's thefts of ocean freight are the kinds of crime which is "seamless" and not readily apparent like a hijacking a rig or seeing some guy walking off the pier with his coat bulging in weird ways and looking 9 months pregnant.
