What Makes a Fly Line Better for Saltwater

First off, you’ll need a fly line that is made especially for saltwater fishing. Anything other than that will result in a line that will quickly crack and break, rendering them useless and you will be out of $50 or more dollars.

So you’ll need one made for saltwater and then you’ll have to get a weight that fits the size of your rod and reel. This will ensure you can cast properly. You’ll need to be able to cast accurately and with occasional distance. A mismatched line will not allow you to do that.

When to Use Saltwater Fly Line

Anytime you’re fishing in saltwater you’ll need a line made specifically for it. You could get away with using a freshwater line for a little while as long as you properly clean it after. Otherwise, it will decay and break quickly.

There are all types of lines that can be used in saltwater. Sinking, floating, float tip, weight forward and they all come in a variety of weights. Allowing you to fully customize and maximize your set up.

You’ll be able to throw heavy lines to tarpon as well as throwing something smaller to sea trout, and smaller ed fish. Allowing you to delicately present smaller flies as well as big ones.

Best Types of Saltwater Fly Line

Below, we’re going to go over several different types of saltwater fly lines. Each of them is going to have its own list of pros and cons. Ensure you think about what kind of line you need and which of the lines below will best help you.

Weight Forward Taper (WF)

The WF taper is regarded as one of the best fly lines for saltwater fly fishing. The first ten feet or so of the line is thicker and heavier. Allowing for strong and accurate casts that will allow you to place a fly gently into the water.

Double Taper (DT)

On a double taper fly line, the first fifteen or so feet will begin to fine very slowly. The rest of the line remains straight. The widening of the line allows for delicate presentations that won’t spook fish.

Level Taper (LT)

The level taper is a straight line throughout. This might be thought of as a pro, but it means it’s actually hard to control except for very specific circumstances. However, it is very cheap and great for a budgeted angler.

Shooting Taper (ST)

Typically, shooting tapers are used in completion settings to see who can cast the farthest. However, they can be great tools for when you want to cover a lot of water with a streamer.

Saltwater Fly Line Weight

The weight of the fly line should correspond with the size of your rod, reel, fish, and fly. You want something that is going to be strong enough to handle the strength of a tarpon.

You’ll also need line that is going to allow you to land a small fly easily in front of a fish’s face. That’s why you can’t just buy one line and use it as a catch-all. Throwing a 4/0 hook on a light line will simply not work well.

Tarpon, larger salmon, and other strong fish will need to use at least a size 10 line. The strength of these fish means you’ll need something strong to move them. While a lighter line will be needed to throw small crab imitations to the noses of redfish.

Length of Saltwater Fly Line

Typically, you’ll be using 40-50 feet of your fly line at one time. Maybe a little bit longer if you plan on throwing a shooting line with a heavy closer attached to the end of it.

Because of this, you’ll most likely have another 50 feet of fly line on the reel. Which is often going to be more than enough to bring a fish in, as long as you have paired the proper weight of the line to the fish.

If you’re still worried about having more line on your reel then make sure you have backing on your reel. Typically you’ll also get 100 feet of that too. Get a strong backing because any fish that takes you that far is usually a good one.

Features to Look for in a Saltwater Fly Line

There are a few different features you need to have when picking out your saltwater fly line. Below we’re going to cover some of the more popular ones that you’re going to need in order to catch fish.

These will include, color, density, taper, as well as being able to stand up to warm and cold climates. There are many other saltwater fly line features, but these are the four that you should always keep in mind.


The color of your fly line is especially important when throwing streamers, or using a sinking line. Stripping a bright orange sinking line through the water would potentially spook the fish you are after.

Choose something that matches the clarity of the water. A dark green or olive could be good for murky water, while a blue or darker shade could be great for clearer water or blue waters you could encounter.


Most coatings added to the best sinking saltwater fly lines have tungsten added to them. The amount of tungsten added is what controls the sink rate of the line. This is important because you need to know how fast your fly falls.

The best saltwater floating line will sometimes have hollow micro balloons added to the coating. This allows the line to sit on top of the water and makes the leader the only part that could sink. Great for throwing shallow or topwater flies.


The majority of saltwater fly anglers are going to use a weight forward taper. The exception being when an angler uses a shooting taper. Allowing them to cast further and search the water for fish.

So, you’ll need to think about what type of fishing you plan one going before you head out. Is this a spot you’ve been before? then a WF will work best. Is this a new area where you’re not sure where the fish will be? Then a shooting will be ideal.

Temperature Control

A lot of saltwater fishing will be done in either very cold water, or in areas where the water is warm but the air is extremely hot. So you’ll need a line that can handle these two extremes.

If fishing in cold northern waters you should make sure the line is set up to handle those types of temperatures. If not, then the line could expand and contract causing breaks and rips.
