Courier ship

A courier ship is a small ship that delivers messages, packages, and mail. Couriers are distinguished from ordinary mail services by features such as speed, security, tracking, signature, specialization and individualization of express services, and swift delivery times, which are optional for most everyday mail services. As a premium service, couriers are usually more expensive than standard mail services, and their use is typically restricted to packages where one or more of these features are considered important enough to warrant the cost.

Often the difference in the time a message would take to be transmitted between two points is fairly small compared to the time it would take a courier ship to make the same journey. However, for speedy delivery of physical mail or packages the Courier Ships are unsurpassed.
