Why boat owners choose HelmWatch
The only boat monitoring platform with AI intelligence, automated safety escalation, and official nautical charts.
Lowest price in the market
$99/year per vessel with unlimited crew access included. Competitors charge $156-$600/year for basic monitoring without AI or safety features.
An AI crew member that knows your boat
HelmWatch is the only monitoring platform with a conversational AI agent. It knows your engine make, maintenance history, and current sensor readings.
Real nautical charts, not Google Maps
Every map view renders your vessel on official Electronic Navigational Charts (ENCs) with depth contours, buoys, and hazards. No competitor does this.
Automated safety escalation
File a float plan and HelmWatch handles the rest. 7-level escalation chain with automatic check-in reminders and emergency contact notification if you don't return.
