Roadmap

Where we're going

From MVP to AI-powered weather intelligence. Here's our plan to build the most capable marine weather platform on the planet.

1

Phase 1 — Live now

Foundation & Launch — shipped

Live today

4D weather visualization (wind particles, waves, currents, isobars)
Smooth weather playback — time-interpolated animation
Comfort-aware routing (4 modes: Fastest → Comfort+)
Motor-out departures + arrival-fallback routing
GFS + ECMWF IFS atmospheres + CMEMS ocean & wave forecasts
Model disagreement heatmap + cross-model route agreement band
Route uncertainty band (models agree/diverge on YOUR track)
Rust isochrone routing engine
Departure planner with weather window analysis
Track My Passage — live voyage sharing
Satellite-sized GRIB export
Email-request routing (subject line in, GPX out over satellite)
Route watches — forecast-drift alerts by email & browser push
Anchor Check — anchorage exposure verdicts
Offline last-forecast cache + installable app (PWA)
Squall-risk layer (surface CAPE)
Chartplotter GPX, Google Earth KML, public developer API + docs portal
Stripe billing with pause/resume; affiliate program

Phase 2 — Depth

Mobile, Offline, & Marine Models

Next

Native iOS & Android apps via Capacitor
Offline weather packs for remote passages
NOAA WW3 wave + RTOFS ocean-current marine models
Anchor Check — full coastline-geometry exposure model
Lightning-strike layer (Blitzortung network)
Tier 1 spectral comfort (JONSWAP reconstruction)
Iridium GO position relay integration
3

Phase 3 — Intelligence

AI, MFD, & Professional Tools

Later

Optical-flow storm advection + CorrDiff AI super-resolution
MFD integration (B&G, Raymarine, Garmin)
SignalK live instrument data for comfort calibration
High-resolution regional models for US, Europe, Canada, and the Pacific
Crowdsourced hazard layer (shoals, debris, whales)
Tier 2 spectral comfort (directional wave spectra)
Custom model building (fine-tune on your region)

Forecast Model Expansion

More models, clearer confidence

OpenSail's roadmap adds independent atmosphere, wave, and ocean-current sources so sailors can see both the forecast and where models disagree.

Global Forecast Core

More independent global models for offshore routing and cross-checking (GFS and ECMWF IFS are already live).

  • ECMWF AIFS
  • NOAA WW3
  • GEM / GDPS

Ocean & Coastal Detail

More current and coastal-water sources for passages near land.

  • RTOFS / HYCOM
  • NOAA OFS
  • Regional tide/current systems

Regional Atmosphere

Higher-resolution wind and pressure where local effects matter most.

  • NOAA HRRR / RRFS
  • DWD ICON-EU / ICON-D2
  • AROME / ARPEGE
  • HRDPS / RDPS

International Expansion

Additional national models as access, licensing, and validation allow.

  • UKV / Met Office
  • JMA GSM / MSM
  • BoM ACCESS

Planned sources are staged behind validation, attribution, and regional coverage checks before they appear in the live model selector.
