A voyage charter involves the carriage of a specific amount and type of cargo from specific load port(s) to specific discharge port(s), subject to various cargo handling terms. Most of these charters are of a single voyage nature between two specific ports, as trading patterns do not encourage round voyage trading. The owner of the vessel receives one payment derived by multiplying the tons of cargo loaded on board by the cost per cargo ton, as agreed to transport that cargo between the specific ports. The owner is responsible for the payment of all expenses including voyage, operating and capital costs of the vessel. The charterer is typically responsible for any delay at the loading or discharging ports.
