# Transship and Preship Cargo

A **transshipment** is the shipment of cargo to an intermediate destination, then by a different vessel to another destination. It is a type of [relet](https://docs.dataloy.com/release-8.16/voyage-management-system/step-by-step-guides/cargoes/maintain-cargoes/cargo-drawer-actions/relet-cargoes) created from a cargo booking from a particular discharge port at the end of an original booking.

A **preshipment** is another type of relet created from a cargo booking. It is the transportation of a cargo from a location to that cargo's load port in an existing cargo booking.

Transshipments and preshipments are listed at the bottom of the cargo drawer under "Relets and Transshipments".
