Boat Polars Database
Free polar diagrams and target speeds for 81 sailboats, sourced from real ORC VPP certificates. Find your boat, discover optimal angles, and sail faster.
Target Speeds
Know exactly how fast you should be going in any wind condition and angle.
Optimize VMG
Find the perfect sailing angles for maximum velocity made good.
Learn & Improve
Understand polar diagrams and use them to race smarter and faster.
Understanding Optimal Angles
Watch three boats sail at different angles. The boat at optimal TWA (True Wind Angle) achieves the best VMG upwind.
Upwind VMG Comparison
True Wind Speed: 10 knots
Key Insight: The green boat sailing at 45° has the highest VMG (Velocity Made Good) upwind, even though it's not the fastest boat speed. This is the optimal angle for making progress toward an upwind target.
