# 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 ![](https://content.gitbook.com/content/md37qFD2XkvN6S9sVg85/blobs/1QJRLE4B3tzv5AzgdPBx/image.png)-icon to **Open** the **Time Charter Contract Drawer**<br>

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.
