## Mariner's Objects

```{note}
**Mariner's Objects** is a standalone option. The availability of the **Mariner's Objects** option depends on the ECDIS license.
```

**Mariner's Objects** — information objects designed for chart enhancement and placing objects and notes by the navigating officer for their own convenience, when discrepancies with ENCs are found that are not covered by Notices to Mariners, or when placing NAVTEX objects.
**Mariner's Objects** are not a substitute for manual updates.

| {{ menu }} → {{ menu_user_chart }} → **Mariner's Objects** |

```{important}
Mariner's Objects form the user chart and are not part of ENC cells.
```

```{seealso}
To display Mariner's Objects on the chart, enable the **Manual Updates layer** in {doc}`**Operational Settings** </sections/graphical-user-interface/operational-settings/index>`.
```

Mariner's Objects are displayed in a separate chart layer. The layer can be disabled.

ECDIS uses an extended list of Mariner's Objects. The navigating officer can add cartographic objects to the user chart.

### Creating a Mariner's Object

To create a Mariner's Object, perform the following steps:

#### 1. Select the object type

Select the Mariner's Object type from the available object types.

#### 2. Select the object geometry

Select the object geometry according to the selected object type.

#### 3. Fill in attributes

Select and fill in additional object attributes.

#### 4. Child object properties

Select and fill in the properties of the parent object's children (if available for the selected object).

#### 5. Metadata

It is recommended to fill in the **Author** and **Source** fields.

#### 6. Place on chart

Place the object on the chart using one of the following methods:

- **Using the cursor** — point to the position on the chart
- **By entering coordinates** — enter exact coordinates manually

#### 7. Coordinate adjustment

Adjust the object coordinates or node coordinates manually, if necessary.

#### 8. Save changes

### User Chart Import

| Menu path |
|-------------|
| {{ menu }} → {{ menu_user_chart }} → **User Chart** → **User Chart Import** |

User Chart import is only possible for a chart created on an identical ECDIS, ECS, or WECDSS.

When importing a User Chart, the current ECDIS User Chart and the imported one are merged.

```{important}
When importing a User Chart, ECDIS does not check for duplicate user objects.
```

### User Chart Export

| Menu path |
|-------------|
| {{ menu }} → {{ menu_user_chart }} → **User Chart** → **User Chart Export** |

User Chart export is only possible for a chart created on an identical ECDIS, ECS, or WECDSS.

```{note}
User Chart export and import allows exchanging user data between systems of the same type, ensuring continuity of navigational information when transitioning from one ECDIS to another.
```

```{danger}
It is prohibited to use **Mariner's Objects** for placing **manual update** objects.
When automatic updates are installed, confusion may arise between automatic update objects and **Mariner's Objects**.
```
