# Maintain Voyages

The details of a voyage can be edited in the **Core**<img src="/files/-M49l8Y73BK_WcqImg2D" alt="" data-size="original">**Voyages** module.

When you have [located the voyage](/release-5.36/voyage-management-system/step-by-step-guides/voyages/find-voyages.md), click it and the details will show in a drawer or panel on the right hand side. Field values can be edited directly.

{% hint style="info" %}

#### Change of vessel and ballast port

Vessel and ballast port can only be changed when the voyage status is "estimate" or "unallocated".
{% endhint %}

### Sections

Sections are used to show the most important information about a sub-item of the voyage. Some sections have an **Open**<img src="/files/-MJW01-51ej4tIuTwVpr" alt="" data-size="line">button to open the section's item in a new drawer.

Voyages on a time charter will have a "TC contract" section, while all other voyages will have a "Performance Cargo" section instead.
