## Description

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.

## Tools

### calculate_visibility_loss
Predicts the loss of visual clarity as the board descends into different water layers

### compare_equipment_impact
Evaluates how adding fins or straps changes the sinking behavior

### estimate_submergence_time
Calculates how long it takes for the board to reach a certain depth

### get_sink_rate
Determines the terminal velocity of a sinking board

## Prompt Examples

**Prompt:** 
```
How fast will a 50L board weighing 20kg sink in fresh water (1000 kg/m³) with a shape factor of 0.5?
```

**Response:** 
```
The terminal sink rate for this board is 0.45 m/s.
```

**Prompt:** 
```
How long will it take for a board with a sink rate of 0.5 m/s to reach a depth of 10 meters?
```

**Response:** 
```
It will take 20 seconds to reach a depth of 10 meters.
```

**Prompt:** 
```
What is the visibility at 5 meters depth if the water clarity is 0.8?
```

**Response:** 
```
The remaining visibility is 67%.
```

## Frequently Asked Questions

**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.
