How do I calculate the drag force for a planing surfboard?

Use the `get_drag_force` tool and set the `isPlaning` parameter to true to account for skin friction in planing mode.

Can I find the speed at which my board starts to plane?

Yes, use the `get_mode_transition_threshold` tool with your board's wetted surface area and shape coefficient.

How much power is needed to maintain a specific velocity?

You can determine this by calling `get_required_power` with your target velocity and the drag force calculated from `get_drag_force`.

This MCP server provides precise hydrodynamic calculations for surfboard design and performance analysis. It allows AI agents to determine the total retarding force using get_drag_force, calculate the energy needed to maintain speed with get_required_power, and estimate deceleration via get_speed_loss. It also identifies the transition from displacement to planing modes using get_mode_transition_threshold.
