How do I find the best place to start my turn?

You can use the `get_optimal_cutback_point` tool. Provide the wave shape, your current speed, and your board type to receive the distance to the ideal initiation point.

Can I adjust for different surfboard types?

Yes, all tools account for board types like shortboard, fish, or longboard to adjust the physics of the turn radius and re-entry.

How do I know if I have enough time to complete the maneuver?

Use the `analyze_section_timing` tool. It calculates the time remaining before the wave section moves past the cutback zone based on your speed and the section speed.

This MCP server provides precise maneuver analysis for surfers. By analyzing wave geometry and board dynamics, it helps surfers determine the exact moment to initiate a turn. Use get_optimal_cutback_point to find the ideal initiation location, calculate_maneuver_radius to determine the turn's curvature, and calculate_reentry_angle to predict the return to the wave face. It also includes analyze_section_timing to ensure the surfer stays ahead of the breaking section.
