Frequently Asked Questions – Simrad NAC-2 Low Current Course Computer
1. What does low current mean?
Low current identifies the computer’s intended electrical load category, not a universal boat application. Confirm compatible drive capacity, wiring, battery, network components, feedback, heading source, software, and calibration requirements before operation.
2. Does it operate a windlass?
No. The NAC-2 manages autopilot steering and does not operate a gypsy, drum, chain, or anchor rope. It is not an electric anchor windlass. Verify separate controls for marine anchor retrieval.
