Article 6
Within a period of two years from the entry into force of this Directive, Member States involved in systems of chartering by rotation shall take the necessary measures to enable shippers to have a free choice between three types of contract: - contracts on a time basis, including leasing contracts, where the carrier makes one or more vessels and crew exclusively available to a customer for a specific period for the transport of goods for that customer against payment of a given sum of money per day. The contract is freely concluded between the parties, - tonnage contracts where the carrier undertakes to transport, for a period laid down in the contract, a given tonnage against payment of cargo rates by the tonne. The contract is freely concluded between the parties and must involve large consignments, - contracts for single or multiple trips.
