FAQ
Questions Sailing VMG Calculator owners ask.
- 01
How do I calculate my apparent wind?
You can use the calculate_apparent_wind capability by providing the true wind speed, true wind angle, and your current boat speed.
- 02
Can I find my best sailing angles?
Yes, the get_optimal_angles capability uses your boat's polar data to find the most efficient upwind and downwind headings.
- 03
What is VMG?
Velocity Made Good (VMG) is the speed component in the direction of your target course. You can calculate this using calculate_vmg_performance.
