### Will A Fishing Line Sink Or Float? (An Engineer Explains!) –

I have been asked a few questions about fishing line physics, both on our Facebook group ( https://www.facebook.com/groups/campingfieldguide/ ) and in the online blog community. It’s a good thing I have a great professor who helped me out with this article.

This blog will be about all kinds of fishing gear, I will try to explain how fishing lines work, the mathematics behind it, why they are used in different ways, what problems they can solve and probably why the first one works.

We all know that fishing line sinks, right? It’s just a basic rule of physics, right?

Because not every fishing line is constructed the same, some fishing lines float while others sink. It’s critical for anglers to understand whether fishing lines may float or sink since it can influence the sensitivity of your line, the movement of your bait, and the presentation of your bait.

Monofilament and fluorocarbon fishing lines will sink in general, whereas braided fishing lines will float. Other variables, such as the protective coating on the fishing line and the salt level of the water, may affect whether the fishing line floats or sinks.

There’s a lot to learn about why certain fishing lines float and others sink. In this article, I’ll peel back the layers of science that go into determining whether a fishing line floats or sinks.

## What’s the Science Behind Floating or Sinking Fishing Line?

To properly comprehend why a fishing line floats or sinks, we must first grasp some fundamental physics.

### What exactly is buoyancy?

Buoyancy is the property that affects whether a fishing line will float or sink. The more buoyancy an item has, the more it will float. The lower an object’s buoyancy, the more likely it is to sink.

The surrounding fluid exerts an upward pull on an item called buoyancy. The amount of upward force generated is determined by the volume of the item that is partly or completely immersed. When the upward force is higher than the object’s weight, it will float. When an object’s weight exceeds the upward force, it sinks.

Large ships, such as cruise ships or freight ships, are built utilizing this basic buoyancy concept, which allows them to float while being composed of steel.

### Major Contributors To The Buoyancy Of A Fishing Line

The density of the fishing line and the water determine its buoyancy.

The fishing line will sink if its density is greater than that of the water. The opposite is also true. The fishing line will float if its density is lower than that of the water.

The greater the density differential between your fishing line and the water, the harder the water will press on the fishing line and the slower the fishing line will sink.

Although the density of water varies based on its salt content, the average density of water is calculated as follows:

• 0.036 lb/in3 (1 g/cm3) in freshwater
• 0.037 lb/in3 (1.25 g/cm3) saltwater

The density of the Dead Sea is 0.045 lb/in3 (1.24 g/cm3), which is 21 percent denser than seawater and so thick that you will naturally float on the water rather than sink.

## Is Monofilament Fishing Line Floating or Sinking?

A monofilament fishing line is a kind of fishing line that is often used by fishermen. However, whether a monofilament fishing line would float or sink in water seems to be a point of contention.

Monofilament fishing line has an average density of 0.0415 lb/in3 (1.15 g/cm3), which is 15% heavier than fresh water and 12% heavier than saltwater. Because the density of a monofilament fishing line is greater than that of water, it will sink in both freshwater and saltwater.

### What Is The Rate At Which Monofilament Fishing Line Sinks?

Since we’ve established that a monofilament fishing line sinks, another common question fishermen have is how quickly a monofilament line sinks.

This is something I’ve thought about as well. So I put on my engineer’s hat, pulled out the calculator, and estimated how long a monofilament fishing line would take to drop 10 yards deep.

 Line Test Monofilament Line Diameter on the Average Freshwater Saltwater 4 lb 0.203mm 0.0079 0.0079 0.0079 0.0079 0.0079 0.0079 Seconds: 17 18 milliseconds 6 lb 0.010 millimeters in 0.254 millimeters sixteen seconds sixteen seconds 8 lb 0.0110 mm 0.0110 mm 0.0110 mm 0.0110 mm 0.0110 mm 1 minute 1 minute 1 minute 1 minute 15 seconds 15 seconds 10 lb 0.305 mm 0.0120 mm 0.0120 mm 0.0120 mm 0.0120 fourteen seconds fourteen seconds 12 lb 0.0140 millimeters in 0.356 millimeters Thirteen seconds Thirteen seconds 14 lb 0.0150 millimeters in 0.381 millimeters Thirteen seconds Thirteen seconds 17 lb 0.401 mm 0.0158 mm 0.0158 mm 0.0158 mm 0.0158 12 second timer Thirteen seconds 20 lb 0.0180 mm 0.0180 mm 0.0180 mm 0.0180 mm 0.0180 mm 12 second timer 12 second timer 25 lb 0.50 mm 0.0197 mm 0.0197 mm 0.0197 mm 0.0197 eleven seconds eleven seconds 30 lb 0.550 mm 0.0216 mm 0.0216 mm 0.0216 mm 0.0216 eleven seconds eleven seconds 40 lb 0.0236 mm in 0.600 10 milliseconds 10 milliseconds 50 lb 0.0276 mm in 0.700 9 seconds 9 seconds 60 lb 0.0315 mm in 0.800 9 seconds 9 seconds 80 lb 0.0354 mm in 0.900 8 seconds 8 seconds 100 lb In 1.000 mm, 0.0394 8 seconds 8 seconds

## Fluorocarbon fishing line floats or sinks.

Anglers often utilize fluorocarbon fishing line as a leader line for a variety of reasons. One of these reasons is because fluorocarbon fishing lines sink in water, making bait presentation easier.

A fluorocarbon fishing line has an average density of 0.063 lb/in3 (1.78 g/cm3), making it 78 percent heavier than fresh water and 74 percent heavier than saltwater. As a result, a fluorocarbon fishing line will sink in both freshwater and saltwater since its density is greater than that of water.

### What Is The Rate Of Fluorocarbon Fishing Line Sinking?

I computed the anticipated time it would take a fluorocarbon fishing line to sink one yard, similar to the monofilament rate of sinking chart.

 Line Test Fluorocarbon Line Diameter on Average Freshwater Saltwater 4 lb 0.180 mm 0.0071 mm 0.0071 mm 0.0071 mm 0.0071 15 seconds 15 seconds 6 lb 0.0087 millimeters in 0.220 millimeters Thirteen seconds fourteen seconds 8 lb 0.250 mm 0.0098 mm 0.0098 mm 0.0098 mm 0.0098 Thirteen seconds Thirteen seconds 10 lb 0.280 mm 0.0110 mm 0.0110 mm 0.0110 mm 0.0110 12 second timer 12 second timer 12 lb 0.300 mm 0.0118 mm 0.0118 mm 0.0118 mm 0.0118 eleven seconds 12 second timer 14 lb 0.330 mm 0.0130 mm 0.0130 mm 0.0130 mm 0.0130 eleven seconds eleven seconds 17 lb 0.380 mm 0.0150 mm 0.0150 mm 0.0150 mm 0.0150 10 milliseconds 10 milliseconds 20 lb 0.0161 mm in 0.410 10 milliseconds 10 milliseconds 25 lb 0.480 mm 0.0189 mm 0.0189 mm 0.0189 mm 0.0189 9 seconds 9 seconds 30 lb 0.500 mm 0.0197 mm 0.0197 mm 0.0197 mm 0.0197 9 seconds 9 seconds 40 lb 0.0236 mm in 0.600 8 seconds 8 seconds 50 lb 0.680 mm x 0.0268 mm x 0.0268 mm x 0.0268 8 seconds 8 seconds 60 lb 0.770 mm 0.0303 mm 0.0303 mm 0.0303 mm 0.0303 7 seconds 7 seconds 80 lb 0.0362 mm x 0.920 mm x 0.0362 mm x 0.920 7 seconds 7 seconds 100 lb 0.0401 millimeters in 1.020 millimeters 6 seconds 6 seconds

## Is Braided Fishing Line Floating or Sinking?

Because of its better throwing, enhanced sensitivity, and ability to float on water, braided fishing lines are often employed for topwater fishing.

A braided fishing line has an average density of 0.035 lb/in3 (0.97 g/cm3), which is 3% lighter than fresh water and 5% lighter than saltwater. Because braided fishing lines have a lower density than water, they will float in both freshwater and saltwater.

## What Does All of This Mean to You…

We covered a lot of ground in this article, but we hope you found it helpful.

Fishing lines made of monofilament and fluorocarbon have a greater density than water, causing them to sink. Because braided fishing lines have a lower density than water, they will float.

The sinking rate of a fishing line indicates how quickly it will sink. The rate of sinking is determined by the line and water density, as well as the line diameter. The sinking rate charts calculate how long a fishing line will take to sink one yard. Use this chart as a reference to determine how long it will take your bait to drop to the required depth.

Tight Lines and Happy Fishing

When you think of a fishing line, you probably think of it as a line that can support hundreds of pounds of weight. However, not all fishing lines are created equal. Some are stronger than others, based on their ability to carry large amounts of weight. Today, I’ll explain how this difference is measured, and why it matters..
