Marlin edge AI box

The brains of your boat.

A sealed aluminium computer that runs Ocean AID's fish-detection models on board. No signal required.

Marlin is an edge AI computer built for the helm. It powers on with the boat, runs on 12 V and sips power while it works. Everything runs on the box, so it works the same offshore as it does at the dock.

Marlin T40 or T120?

Same box, same ports, same software. The T120 adds memory, storage headroom and faster real-time detection, and it's built for what comes next.

Both run the full Marlin live app and every feature available today. Choose the T120 for the more powerful chip and for what's next, starting with Captain Codas.
