# TC Voyages

A **TC Voyage** will not have a **Cargo** Section on the **Overview** Tab like normal **Voyages**, but instead have a **Time Charter Contract** Section displaying the **Time Charter Contract**. In this section you can edit the most important fields on a **Time Charter** directly through the **Voyage Drawer** or click the ![](/files/r2ceXw7FHuVCmsxKANiO)-icon to **Open** the **Time Charter Contract Drawer.**<br>

The **Delivery Port** and **Redelivery Port** fields display the port from the associated Port Call. When you enter a new port, the Port Call and TC Contract will be updated accordingly. Click the ![](/files/r2ceXw7FHuVCmsxKANiO)-icon to Open **Port Call Drawer.**

Both **Duration** and **Rate** fields will be disabled if there exists more than one Duration on the Tc contract, or a Duration has multiple Rates.

The **Calculate Profit/Loss** checkbox is only available while the Voyage still has status **Estimate**, and will toggle calculation of profit/loss based on bunkers.
