## Description

This MCP server provides precise sailing vector mathematics to help sailors optimize their performance. It connects AI agents to critical sailing calculations including apparent wind determination via `calculate_apparent_wind`, efficiency analysis using `calculate_vmg_performance`, sideways drift prediction with `estimate_leeway`, and finding optimal headings through `get_optimal_angles`. It is designed to help navigate complex wind conditions by calculating Velocity Made Good (VMG) and leeway based on boat polar data.

## Tools

### calculate_apparent_wind
Determine the wind conditions experienced on the vessel

### calculate_vmg_performance
Calculate the efficiency of the current heading relative to a target course

### estimate_leeway
Predict the sideways drift caused by wind pressure

### get_optimal_angles
Find the most efficient headings for upwind and downwind travel based on boat characteristics

## Prompt Examples

**Prompt:** 
```
What is my apparent wind if the true wind is 15 knots at 45 degrees and my boat speed is 6 knots?
```

**Response:** 
```
The apparent wind speed is 11.85 knots and the apparent wind angle is 32.4 degrees.
```

**Prompt:** 
```
Calculate my VMG for a target course angle of 20 degrees with a true wind of 12 knots, boat speed of 5 knots, and true wind angle of 40 degrees.
```

**Response:** 
```
Your Velocity Made Good (VMG) is 4.72 knots.
```

**Prompt:** 
```
Estimate the leeway for a boat moving at 5 knots in 10 knots of true wind at a 30 degree angle.
```

**Response:** 
```
The estimated leeway angle is 3.5 degrees.
```

## Frequently Asked Questions

**How do I calculate my apparent wind?**
You can use the `calculate_apparent_wind` tool by providing the true wind speed, true wind angle, and your current boat speed.

**Can I find my best sailing angles?**
Yes, the `get_optimal_angles` tool uses your boat's polar data to find the most efficient upwind and downwind headings.

**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`.
