Model Evaluation

📊 Weather Model Validation & Consensus Engine • HRRR, NAM, GFS, ECMWF, GEM, ICON

🏆 Option 1: Robust Cached-Weight Consensus (Steps 7 & 8) Recommended (Top)

Blends forecasts from all 6 models using performance weights saved in your browser cache. Instantly loads using a quick parallel download.

Weights: ✓ Default Equal

⚖️ Priority Weight Overrides ?

Selected Model Consensus Blend

🏆 Option 2: Real-Time Live Validation & Consensus (Alternative) Less Robust (Bottom)

Downloads 7 days of actual history and past forecasts, evaluates them in real-time to calculate weights, downloads current forecasts, and averages them in a single synchronous operation. Heavy on data, slower loading time (~6-8s), and subject to recent archive data availability.

Set Custom Gybe Angle (TWA)
💡 Downwind VMG: Sailing dead downwind (180° TWA) in a Flying Scot is slow because the Apparent Wind drops. Heating up the angle (sailing at ~142° TWA) builds Apparent Wind, which speeds the boat up enough to cover the extra distance faster.
Active Wind: 10.0 MPH @ 0°
Target True Wind Angle (TWA): 142.2°
Target Boat Speed: 5.3 MPH
Downwind VMG: 4.2 MPH

Starboard Gybe Heading: 142°
Port Gybe Heading: 218°
Total Gybing Angle: 75.6°
