Maritime Insights

Expert guides on voyage planning, route optimization, and shipping industry analysis.

Maritime Insights is the analytical layer of Fairway ETA. The calculator and data hub price the next voyage; this section reads the conditions around it — why a freight rate is moving, how a regulatory cycle reshapes routing decisions, where the market and the physical fleet have drifted out of sync.

The work is organized into five categories — Geopolitics, Industry Analysis, Routes & Voyage Planning, Market Data, and Explainers. Category detail, voice notes, and editorial standards are documented at the bottom of this page.

What Is a Bill of Lading? — The One Document That Proves You Own Cargo You've Never Seen

One piece of paper does three things that no other document in any other industry does simultaneously: it proves the cargo was received, it records the terms of transport, and it transfers legal ownership of goods that may still be at sea. The bill of lading has done this since the fourteenth century. The electronic replacement has gone from 1% adoption in 2021 to 11% in 2025 — and the paper original is still the default.

The Yards Cannot Build Two Things at Once — Why June's Order Burst Is a Zero-Sum Game Between Sectors

In the first week of June, four billion dollars in newbuild orders crossed the desks of yards in China and South Korea. Every slot taken was a slot some other sector cannot have. The global market reads the orderbook as a supply forecast. The yards read it as a production calendar — and the calendar is full until 2028.

Voyage, Time, or Bareboat? — The Three Ways a Ship Gets Hired, and Why the Difference Decides Who Pays for Fuel

The same Capesize bulk carrier can earn $3 million on a single voyage, $50 million over five years on a time charter, or $150 million across fifteen years on a bareboat financing structure. Here's how voyage, time, and bareboat charters actually work — and why one private document still sits at the centre of almost every commercial shipping decision.

What Is Worldscale? — Why a Tanker Chartered at WS 280 Is Not Three Times More Expensive Than One at WS 100

Tanker freight rates are quoted in a strange unit called Worldscale. WS 100 isn't a price. WS 280 isn't "280 dollars" or "280% of the going rate." The system was designed in 1952 to solve a problem the spot market couldn't solve on its own — and it's still in use seventy years later because the alternative is worse.

What Is the IMO? — How One Small Office in London Sets the Rules for Almost Every Ship on the Sea

The International Maritime Organization has fewer than 300 staff, a two-year budget under £80 million, and governs 99% of global trade by volume. Here's how this tiny UN agency works — and why its October 2026 vote could reshape shipping the same way IMO 2020 did five years ago.

The Two Maps of Maritime Labour — Where Crews Come From, and Where They Get Stranded

In 2025, 6,223 seafarers were abandoned across 410 ships — the worst year on record. 82% of the ships flew flags of convenience. But the crews didn't come from St. Kitts or Panama. The labour map and the liability map don't overlap, and that gap is now a commercial risk variable.

How Port Fees Decide When a Ship Actually Arrives

A container ship docking at 02:47 is not random. It is the cheapest hour the port could give it that day. Inside the four clocks — berth, fairway, nautical services, and the queue rule older than container shipping — that decide when a ship actually arrives, and the 9% of voyage time the industry has been trying to recover since 2019.

EU ETS for Shipping Explained — What 100% Phase-In Actually Costs

For the first time, 2026 emissions count fully under Europe's carbon market — and methane and nitrous oxide are inside the scope. Here's what that actually means for a single Asia–Europe voyage: how the cap-and-trade system works, why an EU-to-non-EU voyage is taxed at 50%, what a 10,000 TEU container ship really pays in EU ETS bills (€250,000–€300,000 per Busan-Rotterdam voyage), why container carriers are accused of making €60,000 in windfall margin per voyage on top of the actual cost, and how the UK port arbitrage works. Everything operators trading into Europe need to know about the regulation that just doubled the carbon line on every EU freight quote.

Ice Class Explained — What 1A Super, PC6, and Arc7 Actually Mean

Ice class looks like a single rating. It's actually three competing systems built for different seas — Finnish-Swedish for the Baltic, IACS Polar Class for the global polar regions, Russian Arc for the Northern Sea Route. A 1A Super tanker isn't built for the Arctic. The 15 Yamal LNG carriers serving Russia's NSR are Arc7, not Polar Class. The only PC2 ship in passenger service is a French luxury cruise liner. Here's what the labels actually mean and why the differences decide whether a ship can legally enter a stretch of frozen water.

A Ship's Weight Is Five Different Numbers — And Two of Them Aren't Weight at All

When a news report says a ship is "150,000 tonnes," it could mean five completely different things — and two of them have nothing to do with weight. A ship's tonnage is one of maritime's most confusing pieces of vocabulary, because the word "ton" got borrowed, redefined, and split into a half-dozen meanings over centuries. Here is the plain version: what each number measures, and which one matters when.

The Map Is Changing — Why Most of the North Atlantic Will Burn 0.10% Fuel by 2028

A bunker contract signed in 2024 covered four sulfur control zones. A bunker contract signed in 2028 will cover eight. The Mediterranean went live in May 2025. The Canadian Arctic and Norwegian Sea entered force in March 2026. The North-East Atlantic follows in September 2027. The IMO is drawing a new map of the world's bunker market, and the data from the first year of the Mediterranean ECA shows exactly how the fuel mix changes once a zone goes live.

Container Ships Explained — Feedermax, Panamax, ULCS, and Why They Keep Getting Bigger

Until 1988, the largest container ship in the world carried 4,300 TEU — roughly what fits on the top deck of a modern Megamax. In the 38 years since, container ships have grown by more than five times, with each step named after a canal, a port, or a strait it broke through. A plain guide to the size labels that quietly organize 80 percent of world trade.

The Houston Pattern: Why Bunker Fuel Still Breaks Engines, Five Years After IMO 2020

In 2018, more than 100 vessels suffered fuel pump failures from contaminated bunkers delivered through Houston — under the HSFO regime. In 2023, the same hub delivered a different contaminant in VLSFO from a single supplier, eventually affecting 32 vessels and spreading to Singapore. Five years apart, two contamination events, the same supplier-end supply chain gap. The lessons of 2018 returned in 2023, more expensively. The fuel works. The cost of making it work does not appear in the bunker price quote.

Onboard Carbon Capture (OCCS): The Technology Works. The Infrastructure Doesn't.

Onboard carbon capture has crossed from PowerPoint to commercial deployment. Wärtsilä launched its system to market in May 2025. Around fifteen vessels were operating OCCS by end-2025. The technology captures up to 70% of exhaust CO2. Cost estimates range from $769 per tonne (prototype) to €50–70 per tonne (commercial launch) — a ten-times gap that nobody has explained. The technology works. The infrastructure doesn't. That spread defines who deploys when.

The Two Clocks of Shipping — Why FBX and BDI Stopped Moving Together

On May 22, the Baltic Dry Index fell 9% in a week. The Freightos Baltic Index — container shipping's benchmark, governed by the same Baltic Exchange — barely moved. Two indices, same exchange, two different markets. Maersk's Q1 2026 Ocean EBIT swung from +$743M to −$192M while dry bulk lurched on Hormuz peace narratives. Four freight benchmarks now run on four different clocks. The divergence isn't temporary. It's structure becoming visible.

Bulk Carrier Sizes Explained — Capesize, Panamax, Supramax, and the Rest

Bulk carrier size names look technical but they're really shorthand for trade patterns. A Capesize means iron ore. A Panamax hints at grain or coal. About 70% of the world's seaborne iron ore moves on Capesize alone — which is why a single commodity can move the entire BDI. A plain guide to the size labels that quietly organize the dry bulk fleet.

The Quiet Retreat — Alternative Marine Fuels Just Lost Their Year

For three years, every maritime panel named the same trio as shipping's decarbonization future: methanol, ammonia, hydrogen. The 2025 orderbook said something different. Methanol orders fell 59%. Ammonia recorded five vessels. LNG took 80% of all alternative-fuel orders. Maersk — the carrier that built its brand on methanol — is publicly working through engine reliability and grey-methanol fallback. The narrative didn't change. The capital did.

Geopolitics & Crisis Analysis tracks how chokepoint events become voyage costs. Industry Analysis covers the structural cycle — orderbook, scrapping, fleet age, decarbonization compliance. Routes & Voyage Planning compares major shipping corridors and the bypass options when a corridor closes. Market Data & Indices reads the BDI, freight rates, and bunker prices without ceremony. Explainers breaks down a single concept at a time for newcomers and adjacent-industry readers.

Editorial standards

Standards are kept on the about page. The short version: we cross-verify against primary sources before publishing, we paraphrase rather than quote at length, and we date articles so corrections can be tracked. If a number turns out to be wrong, we update the article rather than letting the original stand.
