Raymarine AIS4000 Class A AIS

The Raymarine AIS4000 Class A AIS transponder is specifically designed for commercial vessels, fishing boats, and serious cruisers operating in international waters. This Class A unit broadcasts your vessel's position, course, speed, and identification to every AIS-equipped boat and coastal authority within range—typically 20+ nautical miles depending on antenna height and sea state.

Built on proven Raymarine engineering, the AIS4000 combines dual VHF receive channels with Class A transmit capability, allowing simultaneous reception and broadcast without gaps in coverage. It integrates with Raymarine chartplotters and multifunction displays via NMEA 0183 or NMEA 2000 protocols, providing live target tracking directly to your navigation screen. The Class A designation ensures compliance with international shipping conventions while delivering superior transmit power—critical when operating in heavy maritime traffic or during emergency situations.

Commercial fishing vessels, cargo operators, and charter captains can benefit from the Raymarine AIS4000 to meet regulatory requirements and reduce risk in congested shipping lanes and busy coastal zones. This device enhances situational awareness and collision avoidance, ensuring that your vessel is visible to others. The AIS4000 is a reliable choice for those who prioritize safety and compliance in their maritime operations.
