How do I calculate the terminal velocity of my board?

Use the `get_sink_rate` tool by providing the board volume, weight, water density, and shape factor.

Can I account for the weight of straps and fins?

Yes, both `get_sink_rate` and `compare_equipment_impact` allow you to include `strapWeight` and `finDragCoefficient` in your calculations.

How does water clarity affect my results?

The `calculate_visibility_loss` tool uses a water clarity coefficient to predict how much visibility remains at a given depth.

This MCP server provides physics-based calculations for board sinking dynamics. It determines terminal velocity using get_sink_rate, estimates time to reach specific depths with estimate_submergence_time, and predicts visual clarity loss via calculate_visibility_loss. You can also use compare_equipment_impact to see how straps and fins affect the descent.
