WindMar Documentation

WindMar is an end-to-end weather-routing and vessel-performance platform for merchant ships, built and operated by a serving master mariner. It combines physics-based performance modeling — calibrated against measured sea-passage consumption — with multi-engine route optimization, safety-aware weather routing, and regulatory compliance tooling.

What WindMar does

• Weather-aware route optimization — multiple independent routing engines cross-check every result; routes are optimized on fuel and constrained by hard safety limits on sea state, wind, and ice.
• Calibrated vessel performance — ship models are fitted to the vessel's own measured consumption, not generic curves, and validated against completed voyages before use.
• Safety-aware objective — routes respect operator-set weather ceilings, avoid resonant sea states, and report the weather actually encountered along every route.
• Extended forecast horizon — global model data with multi-layer visualization: wind, waves, swell, currents, tides, sea surface temperature, visibility, and ice.
• Voyage analytics — baseline-vs-optimized comparison, ETA/fuel confidence intervals, engine-log and noon-report ingestion.
• Regulatory compliance — IMO CII rating and projection, FuelEU Maritime GHG intensity tracking, ECA/HRA/TSS zone handling, charter-party clause verification.

Methodology

WindMar's physics layer is built on published, industry-standard methods — resistance and propulsion estimation in the Holtrop–Mennen tradition, wind loading per Blendermann, wave added resistance per ISO 15016 — extended with proprietary calibration against measured fuel consumption and a proprietary multi-engine optimization stack. Results are benchmarked against commercial routing services on a standing test protocol.

Open-source foundation

WindMar's foundation layer is open source (windmar-demo, Apache 2.0, archived at v0.1.5) — a fully functional self-hosted reference release. Commercial development, including the calibrated performance models, the modern engine stack, and safety-aware optimization, continues on a private line and is not part of the open-source release.
