Voyage charter or time charter: choosing the right instrument

Every dry cargo fixture ultimately rests on one of two instruments. Under a voyage charter, the owner is paid freight to carry an agreed cargo between agreed ports, and bears the voyage costs: bunkers, port charges, canal dues. Under a time charter, the charterer hires the vessel for a period, pays hire, directs employment, and takes the voyage costs onto its own account.

The commercial difference is who owns the consequences of time. On a voyage basis, delay at the load port beyond the agreed laytime becomes demurrage, compensating the owner for lost days. On a time basis, the vessel earns hire whether she waits or sails, so schedule risk sits squarely with the charterer.

When a voyage charter fits

Cargo interests with discrete parcels, defined port pairs, and limited appetite for operational involvement are usually better served by voyage terms. The freight rate wraps the owner's costs and risk into a single number that can be compared across tonnage and dates, and the shipper's obligations concentrate on cargo readiness and laytime performance.

When time charter earns its keep

Traders and operators running repeat programmes often prefer period cover. Control of routing, speed, and rotation lets a capable charterer extract value the voyage market cannot price, and hire converts freight exposure into a running cost that can be hedged or passed through.

The discipline that matters on period business is redelivery: condition, bunkers on board, and permitted trading limits are where disputes concentrate. Clean recap wording at the fixture stage costs nothing; unwinding an ambiguous clause after redelivery costs a great deal more.

How we approach it

Nandan Maritime works both instruments from the cargo side and the tonnage side. The right answer is rarely doctrinal: it follows from the cargo book, the trade lane, and the risk each party is genuinely equipped to carry.
