- **TWD (True Wind Direction):** The compass direction the wind is blowing from.
## Boat Performance
- **BSP (Boat Speed):** Speed through the water (from your speedo).
- **SOG (Speed Over Ground):** Actual speed relative to the earth (from GPS).
- **VMG (Velocity Made Good):** Speed directly upwind or downwind.
- **Polar %:** Your current speed relative to the theoretical maximum for your boat.
## Navigation
- **HDG (Heading):** The direction the bow is pointing.
- **COG (Course Over Ground):** The actual path the boat is tracking (includes leeway and current).
- **Depth:** Current depth below the keel.
