Show Notes

General Average, York Antwerp Rules, and Why the Jason Still Matters

General Average is one of the oldest principles in maritime law — and one of the least understood until something goes wrong. In this episode of The Shipping Lawyer, we take a deep dive into how General Average actually works in practice, why the York Antwerp Rules matter more than many realise, and how a century-old U.S. Supreme Court case involving the vessel Jason still shapes modern shipping contracts. This episode connects the dots between General Average, the York Antwerp Rules, the New Jason Clause, and both-to-blame collision, showing how these concepts operate together as a coherent risk-allocation system — not isolated bits of legal boilerplate. What General Average is, when it applies, and why fault doesn’t matter (at least initially)

What happens after a General Average declaration, including security demands and the role of the average adjuster

How the York Antwerp Rules standardise General Average — and why the version incorporated into your contract matters

Key differences between the 1950 and 2016 York Antwerp Rules, including crew wages, salvage, environmental costs, and interest

The real-world origin of the New Jason Clause, named after the vessel Jason

How the New Jason Clause separates negligence from General Average contribution

Why both-to-blame collision clauses exist, and how they prevent circular and commercially unworkable outcomes

How these clauses appear in BIMCO-style charterparties and bills of lading, and why they stop being “boilerplate” the moment there’s a casualty

General Average, the York Antwerp Rules, the New Jason Clause, and both-to-blame collision clauses are not relics of maritime history. They are practical tools that quietly determine who pays, how much, and in what order when things go wrong at sea. If you’ve ever dealt with a fire, grounding, collision, or salvage operation — or you advise people who do — this episode explains why the contract wording often matters more than fault.

Detention and demurrage invoices land on desks every week, and too often the person holding one can’t say what they’re actually being charged for. This episode goes back to basics. Host Alison Cusack breaks down what demurrage, detention and storage each are, why the same words mean different things depending on who’s sending the invoice, and why it matters before you pay. (And no, it’s not about Dungeons & Dragons. Apologies if you were misled.) In this episode: Demurrage vs detention: same box, two places, two clocks Separate vs merged D&D, and why the label on the invoice won’t tell you which you have Where storage fits, who charges it, and why it runs alongside the other charges What stops the clock (and why customs holds and fumigation usually don’t) Why depot congestion and return directions can change your detention exposure What a lost or delayed bill of lading can cost you The “hat test”: are you even the right party to be charged? A four-question checklist for any invoice: who is charging, what for, are the dates and rates right, and are you liable? If you want a second set of eyes on an invoice before you pay it, not after, get in touch. General information only, not legal advice. Your position depends on your documents and facts, so please get advice on your specific situation before you act.

The charterparty gets signed at speed. The ops team takes over. And the document sits in a folder until something goes wrong. In this episode, Alison breaks down how to manage charterparty risk well — even when you're moving fast. That means understanding your rider clauses, knowing what to do in the days immediately after signing, and using the life of a fixture to set yourself up better for the next one. What we cover: Why rider clauses are powerful — and why a poorly drafted one can create more ambiguity than the gap it was trying to fill The four questions to ask in a post-signing review (and why it's not a six-week exercise) The clause development file: a simple habit that changes your negotiating posture for every future fixture What the clients who manage charterparty risk well actually do differently Key concepts from this episode: Rider clauses — bespoke provisions that sit alongside the printed charterparty form. In most charterparties, they take precedence over the printed form where there's a conflict. Common inclusions: cargo-specific requirements, deviation provisions, off-hire triggers, bunker specifications, environmental compliance, and sanctions provisions. Post-signing review — a focused review of the charterparty after execution to map commercial risk. Not a due diligence exercise; a practical read with four questions: where are the commercial triggers, where are the asymmetries, where are the gaps, and what does the counterparty's performance obligation actually look like? Clause development file — an ongoing record of issues, ambiguities, and desired amendments built during the life of a fixture. The starting point for next time's negotiations.
