Double Haul Casting for Fly Fishing

*Floating the Shenandoah in the Winter Can Be a Nice Break, Even without the Fish*

When you fly fish for musky, casting technique isn’t just important, it’s everything. Musky flies are huge, heavy, and often wind-resistant, which makes them extremely difficult to cast without proper mechanics. Poor casting technique doesn’t just reduce your chances of success; it wears out your casting arm and back. If you’re not casting efficiently, the fish of 10,000 casts quickly becomes the fish of 20,000 sore, frustrating ones.

What Is Double Haul Casting?

The best method for casting large flies long distances is the double haul. A double haul is a fly casting technique where the angler uses both hands to increase line speed during both the back cast and the forward cast. As the rod hand moves through the casting stroke, the line hand quickly tugs or pulls down on the fly line, once during the back haul and again during the forward haul. This tug on the line helps bend the rod deeper, stores more energy in the rod, and transfers that energy to the fly line.

Think of it like giving the line a boost- adding acceleration to the movement of the rod tip to directly increase the speed of the line. A properly timed haul can dramatically increase the length of the cast and reduce the burden of casting heavy flies. The double haul allows casters to shoot line with far less effort and more precision.

For those new to fly casting, learning to haul may feel awkward at first. Start with a single haul and work up to the basic double haul. Use a streamer and a lighter fly rod while you refine the path of the rod tip, the timing of the haul, and the overall casting motion. A good drill: practice your overhead cast with 30 feet of line and focus on applying a short haul early in the stroke and a crisp, abrupt stop at the end.

When to Use the Double Haul

Use the double haul when you need extra distance, more control, or the ability to turn over big flies into the wind. If you’re making a roll cast or working in tight cover, you may not need it, but when you’re trying to push heavy flies out over open water, the benefits of hauling become obvious.

An efficient cast depends on generating additional line speed without exhausting yourself. If the speed of the line is low, the fly won't turn over or land where you want it. That’s why learning the double haul is one of the most important skills for fly fishers targeting musky or any species requiring long casts and heavy gear.

Typical Musky Flies

Just remember: timing matters. Haul too soon, or without coordinating your rod arm and haul hand, and you’ll cause a tailing loop or throw off the energy transfer. The length of the haul and when the haul is applied should match your casting stroke and the amount of line in play.

A Note on Gear

Another important aspect of casting for musky is using a heavy duty rod with a fast action. A fast-action rod has a stiffer tip and will allow you to generate more power in your cast as well as make more accurate presentations. “Roll casts” can be used to make a cast when space is limited or when you need to avoid making too much noise, however, this is difficult with heavier flies. Many fishers I have gone with use an almost upward cast so flies are basically side-armed out. Noise usually isn't a problem when casting for musky, but you definitely want to get as much distance as possible.

Final Word of Advice

Lastly I'd add that if you are concerned about casting all day it is more important that you pick you spots. One or two good casts are better than 10 crappy ones. While musky aren't the most spooky fish, hitting one on the head instead of in front will determine whether the fish follows or goes away. Don't wear yourself out if you know that is going to be an issue. Perhaps even a preemptive Advil might be in the cards. If the casting doesn't make you tired fighting a 50 pound fish will. Just make sure you set it hard!
