Read full descriptionHide full description
VesselAware™ transforms marine VHF voice communications into real-time, geospatial intelligence. VesselAware™ delivers transcribed and translated radio traffic, detected locations, vessel information, and categorized maritime events alongside existing AIS and operational data. VesselAware™ identifies distress calls, hazards, hails, security events, and other activity as it happens, turning previously isolated voice communications into structured, location-aware data. The result is a richer Common Operating Picture that gives watchstanders and decision-makers a more complete understanding of maritime activity across their area of responsibility. VesselAware™ makes boating safer and less stressful by transforming VHF radio communications into easy-to-understand alerts and information. Get notified about urgent calls, nearby hazards, and hails to your boat while seeing relevant vessel activity on a clear map.

Verdict
The clearest difference is in-app purchases: VesselAware at none against CH16's 2. VesselAware also leads on ads (none vs shown) and update cadence (daily vs every 2 months). CH16's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
