Vesper

See and be seen, avoid collisions

AIS is one of the most valuable safety technologies on the water, and Vesper Marine is a leader in smart AIS. An AIS transponder transmits your boat's position and information to nearby vessels and shows you theirs, dramatically improving collision awareness, especially in traffic, fog, and at night. Vesper builds AIS transponders and integrated systems like Cortex that combine AIS, a VHF radio, and boat monitoring with smart features and alarms. By making you visible to other boats and giving you a clear picture of traffic around you, Vesper AIS adds real safety. For boaters who want to see and be seen and watch over their boat, it is leading technology.

Choosing the right product comes down to AIS type and features. A transponder both transmits and receives, making you visible to others, while a receiver only shows you nearby vessels, so choose a transponder for full two-way awareness. Consider integrated systems if you want AIS, VHF, and monitoring together. Confirm the unit works with your chartplotter or display, and that you have a proper antenna and GPS. Register your AIS with the proper authority for an MMSI. Review the product details before buying. With Vesper AIS aboard, you add real collision awareness and safety.
