Helmwise coordinates six specialized AI agents working in parallel to deliver comprehensive passage plans in seconds. Real-time data, conservative safety margins, and professional-grade exports.
Each agent is an expert in its domain, running in parallel via the Model Context Protocol to deliver analysis in seconds.
Aggregates real-time data from NOAA, OpenWeather, and NDBC buoy networks. Multi-model weather forecasting with automatic worst-case scenario selection when sources disagree.
Predicts tides and currents from official NOAA harmonic stations. Calculates ETA adjustments based on tidal current effects along your route.
Calculates optimal waypoints, bearings, and distances using great-circle navigation. Isochrone-based weather routing for the most efficient passage.
Assesses risks and generates GO, CAUTION, or NO-GO recommendations. Identifies restricted areas, finds emergency harbors, and enforces conservative safety margins.
Comprehensive database of 70+ ports across the East Coast, Gulf, West Coast, Great Lakes, and Caribbean. Marina facilities, entry requirements, and local knowledge.
Monitors NAVTEX broadcasts, coast guard alerts, and notices to mariners. Surfaces active navigation warnings along your planned route.
Built for mariners who take safety seriously.
Multi-model weather aggregation from NOAA, OpenWeather, and NDBC buoy data. Isochrone-based routing finds the optimal path considering wind, waves, and currents. Stale data (older than 1 hour) is automatically rejected.
Official NOAA harmonic station data for accurate tidal predictions. Current analysis adjusts your ETA based on tidal flow effects along each leg of your passage.
Every passage plan receives a clear GO, CAUTION, or NO-GO assessment. Conservative safety margins are non-negotiable: 20% clearance under keel, 20% weather delay buffer, and 30% fuel and water reserves.
Detailed information on 70+ ports including marina facilities, fuel availability, entry requirements, approach hazards, and local knowledge. Covers the East Coast, Gulf, West Coast, Great Lakes, and Caribbean.
Export your passage plans as GPX files for import into your chartplotter or navigation app. Generate professional PDF briefings with weather, tidal, safety, and route details for your passage portfolio.
Install Helmwise as a Progressive Web App on your phone or tablet. Access your saved passage plans offline when you lose connectivity at sea. Syncs automatically when back online.
