# Voyage Comparison
The comparison button  can be found as a primary action in the Voyage drawer:
Comparison functionality in the Voyage drawer
### Overview
In this view, you are able to have an overview of the voyages to compare, copy the voyages you want to compare and/or open the Voyage drawer of the voyages:
Voyage Comparison view
In this early implementation, you are able to *view* and *compare* the values in the **Profit/Loss section,** and in the **Vessel section** also *edit* the fields, between the voyages. The voyage you **are** **comparing** **to** is the left-most voyage. When you use the **copy**-function to the right of the table header, you copy that specific voyage. Meaning, the values will initially be the same, until you alter the values yourself.
The Vessel section of the comparison allows you to choose and edit many values that can change your result. Want to see how another vessel would perform on a given voyage? How much difference will different speed orders or bunker prices make? Make a copy, change the values in the comparison section, and see how it affects the key metrics for the Voyage.
Not all of the fields can be changed in the Comparison view (i.e. the Profit/Loss section). However, many of the fields in the Vessel section can be edited by choosing from the dropdown or edit directly in the input field. Number values also shows the adornments. By clicking the **reference number** of the voyage (blue numbers) to the left of the table header, you will **open the Voyage drawer** of that specific voyage. Here, you can view and/or alter the all of the voyage's field values. The changes will be reflected in the comparison table.
