# Canal Allowances Certain voyage routes require specific canal allowances to be used. These allowances can either be applied to the entire voyage or to individual legs. ## Voyage Allowances Canal allowance settings for the entire voyage is shown in the top right corner of the map in *voyage drawer*. Changing these allowances affects all sea passages on the voyage. For example, consider the following voyage going from New York > Los Angeles > New York:

The voyage is currently allowed through the Panama Canal, and the route and schedule reflects this. If Panama Canal is deselected in the allowance settings, all instances of the canal are removed from the voyage:

However, note that changing allowance settings will not affect sea passages that are already completed (where the E*nd of Sea Passage date* is fixed). ## Port Call Allowances Canal allowances can also be controlled for a single leg on the voyage, by going to the *port call drawer:*

Canal Allowances Port Call Drawer (bottom right)

Changing these allowances only affects the sea passage leading to this port call. For example, if Panama Canal is deselected on Los Angeles port call, it is only removed from the leg going from New York to Los Angeles. Meanwhile, the canal is still used on the way back to New York:

## Default Allowances When creating a new voyage the system applies a set of default canal allowances. These can be controlled by Administrators on the *system settings page*:

Initially, the system default allowances apply to all users when creating new voyages. However, each user can override the system defaults through their *user preferences page*:
