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.

Works with your existing hardware

Compatible with SignalK, NMEA 0183, and NMEA 2000. No proprietary sensors required. Add the HelmWatch Gateway for cellular connectivity on any vessel.

Free crew access for everyone

Invite family, friends, and crew at no extra cost. Role-based permissions let you control exactly what each person can see and do.
