A coaster loading aggregates on the Bristol Channel on a Monday. The cargo is worth what somebody offered on Friday, the ship burns the same fuel whether she is full or two thirds full, and the owner had no part in setting the price of either.
Somewhere on a screen that morning, the rate moved. Nobody in the business moved it, nobody in the business can move it, and every voyage for the next two years will be priced off it.
A shipping line owns or charters ships and sells space on them at a freight rate it does not control. When the rate is high every voyage prints money. When it falls below the daily running cost there is very little to do except keep sailing, because a laid-up ship still owes the bank.
You are a price taker on every voyage
The number the whole trade turns on is the freight rate per box, or per tonne, against the daily running cost of the ship carrying it. Everything else is detail.
That running cost does not flex. Crew, insurance, stores, maintenance and finance are there on a day at sea and on a day at anchor. Fuel moves with the miles, and fuel is the largest single variable, but even a ship doing nothing is expensive. Laying up is not the escape it sounds like: a ship earning nothing still needs a crew to keep her safe, insurance to keep her covered and a berth to sit in, and somebody has to pay for all three.
Around forty pence in the pound survives the direct cost of a voyage in a normal market. In a bad one the figure goes negative and stays there for a year, and the business that survives is the one that could carry twelve months of losing voyages rather than the one that was cleverest about routing.
Every customer is a business, every cargo is a negotiation, and competition is as hard as it gets. There is no loyalty in a rate.
The charter outlasts the cycle
The real trap is timing, and it is a structural one rather than a failure of nerve.
Charters are fixed for years. Rates move in months. A line that took tonnage at the top of a cycle carries that commitment all the way down, paying daily hire on a ship that cannot earn its hire, and there is no clause that lets you hand it back because the market changed its mind.
Run the same logic the other way and it is the best opportunity in the trade. A ship bought or chartered in a bad year is the cheapest capacity anybody has, and when space goes short the rate can double in a quarter. Second-hand tonnage acquired in the wrong-looking month has made more money for more shipowners than any amount of commercial cleverness.
There is a third move that keeps small lines alive. When your own market is weak, charter your ships out to a larger line and run the office on the commission. A Humber feeder operator with two small container ships can sit out a bad year that way, earning nothing on the trade but not bleeding on the assets.
Entry runs from about £5,000,000 to £45,000,000, which buys second-hand coastal or feeder tonnage rather than anything large. There are perhaps three hundred firms of any size in the British trade and something like twenty thousand people in it, which describes the size of the trade rather than counting it. A ship's officer costs around £52,000, and the crew is the one cost you cannot reduce without losing the certificate that lets you sail.
Two authorities can stop the ship
The ship is registered under a flag, and the flag state is the first regulator. For a British-registered vessel that means the UK Ship Register and the Maritime and Coastguard Agency.
The company holds a document of compliance under the international safety management arrangements, and each ship holds the certificate that pairs with it. There is a certificate covering crew accommodation, hours and employment terms under the maritime labour rules, and a security plan the ship has to work to when calling at a port facility.
Two powers matter commercially. The first is detention: any port that inspects your ship can hold her until a deficiency is corrected, and that is a port you chose to call at with a cargo you had already sold. The second is worse. Suspension of the company's safety management document is not a problem for one vessel, it is a problem for the fleet, because the document belongs to the operator rather than the hull.
Underneath that sits ordinary commercial cover, goods in transit among it, because the cargo is somebody else's and the claim will be against you.
Most of the revenue never sees VAT
International freight transport is zero rated under the VAT Act 1994, Schedule 8, Group 8, item 5.
For a line running to the near continent, that is most of the invoice book. The freight moves, the customer is billed, and no VAT is added to the international leg at all. Only the domestic coastal leg is standard rated, which for a feeder or a coaster is a modest share of the total.
It is a quieter treatment than most trades get and it removes a familiar set of problems. It also removes a familiar cushion: there is no large VAT balance moving through the business, so the cash position on any given week is exactly what the voyages earned.
It ends when the rate goes under the running cost
The failure is almost always the same sequence, and it takes about two years.
Rates fall below the daily running cost while the charters are fixed for two more. The ships sail at a loss because laying them up costs nearly as much as running them. You charter out what you can, cut what can be cut, and discover that the crew, the insurance and the class surveys are not negotiable. The finance on the tonnage you own is the thing that finally goes unpaid, because it is the only bill without a person on the other end of it who can stop the ship tomorrow.
That is what makes a line different from a ferry. A ferry sells a timetable to the public and can adjust its fares. A line sells space on the open market at a price somebody else set, and can be undone entirely by having taken the right ship at the wrong moment.
Where this shows up in the game
Shipping Line is one of the specialist trades in Business Baron, and the full game is the floor it stands on.
The monthly decision is whether to charter tonnage in for the season or sail with what you own, at a rate you will be locked into long after the market has moved on. The number you watch is the freight rate per box against the daily running cost of the ship, and the game moves the rate on you rather than letting you price your way out of a bad quarter. Autumn peak is when both the rate and the available ships go tight.
The Maritime and Coastguard Agency and the flag state turn up as inspections, and a detention costs you a voyage you had already sold. The way it ends is a long one: the rate under the running cost, the charters fixed, the ships sailing at a loss because stopping them costs more, and the finance going unpaid last. The Shipping Line page sets out the setup range, the margin and the certificates involved.
