Orca is a navigation system designed for the modern boater.

Contrary to traditional navigation systems, several experiences in Orca require an active internet connection to function. This article explains how Orca functions with and without an internet connection.

The design principles of Orca

Orca is built to function as a primary navigation system in a fully offline environment, with similar capabilities to that of a traditional chartplotter. In Orca, charts can be downloaded and stored on your device for offline access. Positioning, boat controls, instruments, and automatic routing for engine work fully without internet access.

Orca and internet connectivity
