If you fly fish in salt water, the double haul is not optional, it is the skill that lets you punch a cast into the wind, reach fish that are out of range, and turn over a big fly. Casters who struggle in the salt are almost always missing (or fighting) the haul. Learn it and the whole game opens up.
What the haul does
A haul is a sharp pull on the line with your line hand, timed to the casting stroke, and it does one thing: it dramatically increases line speed. More line speed means tighter loops, more distance, and the ability to cut through wind. The double haul simply adds a haul on both the backcast and the forward cast, doubling the effect.
How to build it
- Groove the timing first. The haul happens during the power stroke, a quick down-pull as the rod loads, then the line hand drifts back up to feed line.
- Practice on grass with a marked line, one haul at a time, until the pull-and-return feels automatic.
- Keep it crisp and short. A haul is a quick snap, not a long drag, timing and speed matter far more than how far you pull.
Tip Learn the double haul on the lawn, not on the beach with a fish in front of you. Grooving the timing with no pressure, ideally with an hour of instruction, saves a whole season of frustration when it counts.
