TL;DR: Vessel chartering is the hiring of a ship to move cargo, agreed between a shipowner and a charterer, usually through brokers, and recorded in a charter party contract. The process runs from cargo enquiry through offers and counter-offers to a fixture, with the charter type (time, voyage or bareboat) deciding who controls the ship and who pays for what. The commercial edge sits in vessel selection: choosing the ship whose speed, consumption and emissions profile actually fits the cargo, which is a data decision, not a gut one.
What is vessel chartering?
Vessel chartering is the process of hiring a ship, or space on a ship, to carry cargo. One party owns the vessel; the other, the charterer, needs cargo moved and rents the ship's capability for a voyage or a period. The commercial terms, who pays for fuel, ports and delays, at what rate, with what obligations, are recorded in a contract called the charter party.
Chartering is the market mechanism behind most of the world's bulk trade: iron ore, grain, crude, products and chemicals all move on chartered tonnage, matched to cargoes voyage by voyage.
Who's who in ship chartering
Four roles do most of the work. The shipowner provides the vessel and, under most charter types, the crew and technical management. The charterer needs the cargo moved: a trader, an industrial producer, or an operator who charters in tonnage to run it commercially. The shipbroker sits between them, matching cargoes to ships and negotiating terms for a commission. The operator then runs the fixture day to day: nominating agents, managing bunkers, watching laytime.
The chartering process, from enquiry to fixture
The sequence is remarkably consistent across trades:
Chartering by segment: tankers, dry bulk and containers
The mechanics differ by trade. Tanker chartering leans on voyage charters priced in Worldscale, with vetting acting as a hard gate on which ships can be fixed at all. Dry bulk chartering mixes voyage and time charters across size classes from Handysize to Capesize, with the Baltic indices as the market's reference points. Container tonnage is mostly time-chartered to liner operators for months or years. The charter types themselves are covered in depth in time charter vs voyage charter.
How data changes vessel selection
Most chartering decisions are still made on position lists and broker descriptions: where the ship is and what it claims to consume. The gap between a ship's described performance and its actual performance is where voyage economics are won or lost, because speed and consumption drive the freight calculation, the CII exposure and, since carbon pricing, the voyage's emissions bill.
This is the problem Charter Select works on: comparing candidate vessels on modelled real-world performance for the intended voyage rather than on paper descriptions, so the fixture is priced on how the ship will actually sail. Operators like TMA Bulk already treat vessel and voyage decisions as one commercial optimisation, and the classic selection mistakes are covered in avoiding chartering pitfalls.
The bottom line
Chartering is a matching market: cargoes to ships, risk to price. The process is standardised; the edge is in the inputs, and the biggest input is choosing the right ship on real performance data rather than a description.
