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.

4 tools expose this connector's capabilities to your AI agent.

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

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

The apparent wind speed is 11.85 knots and the apparent wind angle is 32.4 degrees.

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.

Your Velocity Made Good (VMG) is 4.72 knots.

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

The estimated leeway angle is 3.5 degrees.

You can use the `calculate_apparent_wind` tool by providing the true wind speed, true wind angle, and your current boat speed.
