Navigation computers
Zora runs on the main unit and opens in a web browser, so any computer on the boat's network can show it. For a fixed navigation screen, the Mini PC is the tested choice: it comes set up and opens Zora on its screens by itself. If you use your own computer instead, this page says what it needs.
Browser
Use Chrome or Edge, kept up to date, with hardware acceleration on. Firefox and Safari work too. If the browser lacks something Zora needs, Zora says so when it starts, with Browser Compatibility Issue and the versions it supports:
| Browser | Version |
|---|---|
| Chrome | 108 or later |
| Edge | 108 or later |
| Firefox | 101 or later |
| Safari | 15.4 or later |
Do not open Zora in a private or incognito window. Zora keeps its settings in the browser and will not start without that storage.
Turn off energy saving for the browser, so it does not slow Zora down in the background.
One or two screens
At least:
- Intel Core i5 8th generation, or a similar AMD processor
- 8 GB of memory
- Intel UHD 620 graphics or newer
- A 2K output for each screen
This runs Zora on one or two screens, but can feel slow with busy screens.
Two or three screens
- Intel Core i5 12th generation or newer, or AMD Ryzen 5 5600 or newer
- 16 GB of memory
- Intel Iris Xe or AMD RDNA2 graphics
- A 2K output for each screen
For three screens, a small graphics card is the safe choice, such as an Nvidia GTX 1650, a low-power RTX, or an AMD RX 6400, with three HDMI, DisplayPort or USB-C outputs. A small fanless computer needs good airflow.
Mac mini
A Mac mini runs Zora smoothly and silently. The M1 and M2 drive two screens, the M2 Pro three. Use Chrome or Edge, and a wired network connection.
Raspberry Pi
Do not use a Raspberry Pi for navigation. A Raspberry Pi 5 runs Zora, but slows down with widgets, charts or a second screen, and is not dependable for continuous use.
Network
Zora runs on the boat, so what matters is the connection to the main unit, not the internet. Use wired Ethernet or Wi-Fi 6 with a strong signal. Low delay matters more than speed: under 10 ms to the main unit, and 20 to 50 Mbit/s is plenty.
