Learn Curve Casts

Curve casts deliver drag-free drifts and precise fly placement that straight casts cannot match — curving left, right, upstream, and downstream to solve presentation problems on any water. Mac Brown has taught curve casts since 1987 and used them on the first day of fly casting programs at Western Carolina University — where all 30 beginner students could throw curves left and right within a single session. There are five curve cast types, each produced by a specific combination of loop plane, rod plane, and acceleration rate.

Learn Curve Casts

There are many different methods for learning to use curves for presentational casts. They also have a specific intent for matching the water current to either drift with no drag or actively reposition the fly. Learn curve casts to enable you to raise and lower your flies when fishing rivers and streams at a distance.

These specialty fly casts need to be learned on grass before you fish, because a goal without a plan is just a wish!

Learn curve casts to enhance your presentation in all directions when fishing. Many believe curves are used only for across-current presentations. Imagine presenting your fly patterns directly upstream. Using a curve enables the pattern to cover a much greater distance without the fly line shadow directly above the fish you're trying to deceive!

Fly casting is full of principles, fundamentals, mantras, and whatever else you want to call the theory of fly flinging. Your personal journey as a fly fisher will be enhanced when you first break away from all the rules. You need to think outside the box for your presentation to really take off. Intent and specific goals for every practice session are important!

The following suggestions for curve casts help open hundreds of potential layouts. Creative practice on the grass will help you solve presentation problems you couldn't perform on the stream. The fishing problems of presentation are and always will be your greatest teacher. The highlighted text in red will help show just how rules are meant to be broken for gaining greater control.

Loop Plane Curve Casts

Many seasoned anglers would call these types of curves advanced casts. The loop plane helps determine the potential curves at your disposal. I taught these curves for the fly casting programs at Western Carolina University on the first day of class. All thirty beginner students could throw the curves left and right, which emphasized to them that they are in charge of the outcome! For a deeper look into loop planes used in fly casting, here is a link.

All unrolling loops either fail to straighten, straighten, or have excess energy remaining, which leads to a kick. The kick is actually a wave reversal that backs up toward you, the caster. I used the terms negative and positive casts for teaching these types of curves in 1987. It may benefit you to brush up on a few terms here for the descriptions of these casts.

Negative Curve Casts

Negative curve casts are performed with very little rotation for the final delivery stroke. Power application is very different than what you learned for pick-up and lay-down casts. The rod points directly ahead toward the completion of the slow traveling fly line. Rod fade is implemented to reduce the rod leg tension, which causes the fly line to land in a 90-degree curve. Rod fade is the method you must use to develop consistency in the placement of the curve. The finesse of learning many different applications to power the loop is up to you, the fly fisher!

Positive Curve Casts

Positive curve casts offer many new concepts to emphasize for enhancing the resultant curve. On the final delivery, throw faster with a tight loop and stop the rod perpendicular to your target. If you want a larger curve, you can also tug the line right after stopping the rod or implement a greater pullback on the rod.

Flicking a beach towel to break the sound barrier is a great analogy for understanding positive curve casts. The pullback on the towel causes the end to speed up. Hence, the greater pullback will also lead to larger curves used for fishing. When you use this same concept with a vertical loop plane, you have mastered the Tuck cast! It's very practical for sinking your flies in a hurry!

Transverse Waves for Curve Casts

A wave introduced to the unrolling loop is made by moving the rod tip at a right angle (perpendicular) to the target. This move may occur during the casting stroke or after the rod stops. In fact, if you wanted to be really creative, you could attempt both for the same cast! The flow of this movement can be represented by the symbols > or <.

Everyone will have different appreciations for this cast and what it opens up for potential presentations. I like to think of transverse wave casts as snap casts introduced at right angles. The rate of these snap movements is important because you have both curves at your disposal! The rod tip path is very different than what you learned for all of the straight-line mantras.

For example, using a vertical rod plane and loop plane, travel out slow and recover fast. This should enable big right-angled curves to occur in front. Now, using the same vertical rod and loop plane, travel out fast and recover slowly. The curve is opposite, to the left.

Remember, your actions during the casting stroke will influence the fly leg of the unrolling loop. Line mend is the fly line reposition move after the stop. The line mend affects the rod leg of the loop. Learn to use these motions before the fly line lands! How cool is that! Accomplish your goal with a proper layout in the beginning!

Circle Casts for Curves

Circle casts can be used for curves as well by implementing rod fade when you're ready to lay the line down on the water. Using a counterclockwise rotation with a vertical rod plane, implement a change in rhythm with a brief stall before delivery. Fade the rod down in front once you're near the target area. This produces a large curve to the right. The pause is very different than what you learned for straight casts.

Now, using the same motion as described above, accent the forward delivery and you have a large curve to the left. Circles are often easier to control than straight-line casts because they maintain constant tension at all times. Learn to throw circles all around your body and in all directions to open up many new areas of discovery in your casting game. Learn curve casts by playing around with circles to increase your presentations.

Skewed Line Curve Casts

It is a well-known fact that the 180-degree rule is most efficient for teaching accuracy and distance. Learn to skew the backcasts by deviating from the 180-degree rule for dealing with obstacles. My friend Al Buhr has some great examples in his book Two-Handed Fly Casting that provide illustrations. When you skew the fly line on the backcast, you are altering the forces made for the forward casts. Al's Cut Cast is a great example of using the skewed line for a presentation with intent! Learn to skew the 180-degree rule and what you can accomplish for creating greater control with the layout.

Frequently Asked Questions

What is a curve cast in fly fishing?

A curve cast delivers the fly line, leader, and fly in a curved layout rather than a straight line — curving left, right, upstream, or downstream to achieve a drag-free drift around conflicting currents or to place the fly in positions a straight cast cannot reach. Curve casts are controlled by loop plane, rod plane, and the rate of acceleration applied during the casting stroke. There are five distinct curve types each with specific fishing applications.

What is the difference between a positive and negative curve cast?

Negative curve casts use very little rotation on the final delivery stroke — the rod points directly toward the target at completion and the underpowered loop falls in a curve. Positive curve casts use greater than normal force — the loop travels with excess energy that kicks into a curve at turnover. Negative curves produce softer presentations. Positive curves produce tighter, more driven curves useful for reaching under overhanging vegetation.

When do I need a curve cast for trout fishing?

Any time a straight cast would drag the fly — when currents between you and the fish run at different speeds, when the fish is holding around a bend or behind an obstacle, or when you need the fly to land upstream of the fish with the leader already curved away from the fish's window. Curve casts are also used to raise and lower flies in the water column at distance — a technique most anglers never develop.

How do I learn to throw curve casts?

Start with the horizontal rod plane cast close to the ground — this lets you see the loop traveling and the curve forming without losing track of the line in the air. Practice negative curves first — reduce power gradually on the delivery until the loop fails to straighten and falls in a curve. Once the motion is understood add positive curves by increasing force and rotation. Mac Brown's beginner students at WCU threw curves left and right on day one — it is a learnable skill with the right instruction.

Where can I learn curve casts from a certified instructor?

Mac Brown Fly Fish in Bryson City, NC offers private fly casting lessons covering all five curve cast types, loop plane control, and advanced presentation casts — led by Mac Brown, the only FFI Master Casting Instructor in North Carolina, teaching curve casts since 1987. Online lessons available worldwide via FaceTime, Zoom, or Skype at $400 per session.

What is a transverse wave curve cast?

A transverse wave curve cast introduces a wave into the unrolling loop by moving the rod tip perpendicular to the target — either during the casting stroke or after the rod stops. Moving the rod tip out slow and recovering fast produces a large curve to the right. Moving out fast and recovering slowly curves the opposite direction. The direction and rate of the snap movement control which curve you produce.

What is a circle cast and how does it create a curve?

A circle cast maintains constant tension throughout the stroke by rotating the rod in a circular path rather than a straight back-and-forth motion. To produce a curve, implement rod fade — a deliberate lowering of the rod toward the target — near the delivery point. A counterclockwise rotation with a brief stall before delivery produces a large curve to the right. Accenting the forward delivery from the same motion produces a large curve to the left.

What is rod fade and why does it matter for curve casts?

Rod fade is a deliberate reduction of rod tip speed and rotation during the final delivery stroke — used to underpower the loop so it fails to fully straighten and falls in a curve. It is the core technique behind negative curve casts and is what separates a controlled presentational curve from an accidental tailing loop. Without rod fade, negative curves land randomly. With it, the caster controls the size and direction of the curve consistently.

What is a skewed line curve cast?

A skewed line curve cast deviates intentionally from the 180-degree rule by angling the backcast away from the straight-line path of the forward delivery. This skew alters the forces acting on the forward cast and produces a curved layout. Al Buhr's Cut Cast — detailed in his book Two-Handed Fly Casting — is a practical fishing application of the skewed backcast that delivers the fly around obstacles with precise directional control.
