In shipping disputes, the risk that sinks a case is rarely the loud one. It is the quiet erosion of a strong position through well-meaning correspondence.

A charterer comes to you with what looks like a clean position. The vessel is late. The owners keep asking for “just one more extension.” Each request is polite, reasonable on its face, and wrapped in assurances that loading will begin any day now. The instinct is to keep accommodating. Commercial relationships matter, and no one wants to be the difficult party. That instinct is exactly where strong cases go to die.

The risk hiding in plain sight

Under English law, a party holding a right to cancel, or to terminate for the other side’s breach, can lose it. Not by signing anything away, but by conduct. If your words and actions taken together clearly and unequivocally show that you are treating the contract as alive and continuing, with knowledge of your right, a tribunal may hold that you have affirmed it. The principle is well settled - mere delay or continued discussion does not, by itself, amount to waiver. But the line is not always where you would expect, and the other side will lean on it.

This is the trap. A counterparty in difficulty has every incentive to keep you talking. Every unqualified extension, every accommodating email, becomes raw material for a later argument that you affirmed the contract, that you waived the breach, that your “clear” position was never so clear after all.

Strategic ambiguity is a tactic, not an accident

We have seen this often enough to treat it as deliberate. Drawn-out “good faith” negotiations can be used to blur a clean entitlement. The longer the correspondence runs, the more crowded the record becomes, and the easier it is for a defaulting party to argue, months later in front of an arbitrator, that the conduct was equivocal and the position muddy. A once-obvious right starts to look contestable. You never know what the record will be asked to carry until you are in arbitration. So you build it to carry weight from the first exchange.

How we protected our client

In a recent Black Sea grain voyage charter, our client, the charterers, faced precisely this scenario. The vessel never performed. Extension requests kept arriving. We held a disciplined line:

• We refused open-ended accommodation. Where an extension was given at all, it was limited, time-boxed, and granted on terms rather than as an open courtesy.

• We reserved rights in writing, expressly and repeatedly. Each communication preserved the client’s position instead of quietly conceding it.

• We rejected the “mutual cancellation” framing the owners proposed. Cancellation by mutual agreement is a consensual discharge that can release both sides from their claims. That is the last thing a charterer holding a damages claim should accept. We cancelled unilaterally and accepted the owners’ repudiatory breach instead, reserving all rights to damages.

• We served a clean notice of cancellation, drafted to withstand scrutiny.

The effect was that the client’s legal position at the end of the saga was as strong as it had been at the start. Nothing had been waived. Nothing had been blurred.

From firm position to binding settlement to arbitration-ready

A protected position is leverage, and we used it. The owners were brought to a binding settlement: a full and final compromise with a clear payment obligation, structured so that the release took effect only on actual receipt of funds, not on a promise to pay.

The settlement had converted a contested charterparty dispute into a clean debt claim, and we were ready to enforce it through LMAA arbitration without delay. Discipline at the beginning is what made the endgame simple.

Five takeaways for charterers and owners alike

1. Reserve your rights in writing, every time. A standing reservation costs nothing and preserves everything.

2. Treat each extension as a decision, not a courtesy. Limit it, time it, and put it on terms.

3. Never accept “mutual cancellation” if you have a claim. Cancel unilaterally or accept the repudiation, and reserve damages.

4. Assume your correspondence will one day be read by a tribunal. Build the record to survive that reading from day one.

5. Turn leverage into a binding settlement, and draft it to be enforceable. A compromise is only as good as the day you have to sue on it.

The discipline that wins

Strong outcomes in shipping disputes are seldom the product of last-minute heroics. They come from discipline exercised early, when the stakes feel low and the easy path is to keep accommodating. Hold the line at the right moment, and the rest tends to follow.
