Fly reels
Tackle · Last reviewed 2026-08-10
Mostly a line store, and occasionally the only thing between you and a fish that has taken all of it.
For most trout fishing a fly reel is a place to keep line. Fish are played by hand, line is stripped and held in loops, and the reel barely turns. Anybody choosing a first outfit should spend accordingly.
That changes entirely with fish that run. A salmon, a big sea trout or anything saltwater will take line past the loops in your hand and onto the reel, and at that point the drag becomes the only thing controlling the fish. A reel that stutters at the start of a run breaks tippet; one with insufficient capacity runs out of backing.
The practical distinction is therefore between a line-store reel and a fighting reel, and the specifications that matter differ completely between them. Arbor size affects retrieve rate and how much the line coils; capacity is quoted as a line class plus a length of backing.

What it does
Stores the fly line and its backing, balances the rod at the handle, and — on species that run — provides a smooth braking force that gives line before the tippet reaches its limit. On species that do not run, it does the first two jobs and very little of the third.
How to choose one
- Match the reel to the line class so the outfit balances at the handle.
- For trout, prioritise weight and balance; for anything that runs, prioritise drag smoothness.
- Startup inertia matters more than maximum drag — the first moment of a run is when tippet breaks.
- Check capacity in line class plus backing length, and take the backing seriously for salmon and saltwater.
- A large arbor retrieves faster and leaves the line with a wider coil memory.
What the numbers mean
LINE CLASS RANGE, such as '5/6', is the line weights the reel is sized for. CAPACITY is quoted as a line plus backing, e.g. 'WF6F + 100 yd of 20 lb backing'. DRAG TYPE is usually disc or click-and-pawl; disc drags are smoother and stronger, click-and-pawl are simpler and traditional and are perfectly adequate where fish do not run. ARBOR SIZE — standard, mid or large — affects retrieve rate and line memory.
Care, and how it fails
Rinse in fresh water after saltwater use and dry before storing. Back the drag off when the reel is put away, for the same reason as any other reel: leaving friction surfaces compressed for months produces a sticky drag that will lose a fish. Check that backing knots are sound before a trip where they might actually be reached, which is the moment nobody wants to discover them.
A line store in fresh water and a brake in salt
The fly reel is the one component whose importance changes completely depending on what is being fished for, and buying advice that ignores that is why people own the wrong one.
IN MOST TROUT FISHING IT IS A LINE STORE. The fish is played by hand on the line, the reel holds what is not being used, and the drag is barely engaged. A simple click-and-pawl reel that balances the rod is entirely adequate, and it is what generations of river anglers used without disadvantage.
IN SALT AND FOR ANYTHING LARGE IT IS A BRAKE, and the requirements change completely. A bonefish, a bass in current, a trevally or a tarpon runs further and faster than a hand can control, and the fish is played from the reel. That needs a drag that is smooth from the very start of the run — startup inertia is the specification that actually breaks tippets — and it needs to keep working while soaked in salt water.
BACKING CAPACITY STOPS BEING A NUMBER ON A BOX. A hundred metres of backing is ample for most temperate fishing and inadequate for tropical fish that run further than that in one burst. It is worth checking rather than assuming, because it is the one specification that cannot be worked around on the day.
ARBOR SIZE IS PRACTICAL RATHER THAN FASHIONABLE. A large arbor recovers line faster per turn and puts the line into wider coils, which reduces the memory that makes a cold-stored line coil like a spring. That matters more in practice than most of what is written about it.
AND THE SALT REQUIREMENT IS ABOUT SEALING AND MATERIALS. A drag that is not sealed will take salt into itself and seize, usually some weeks later and always without warning. Rinse in fresh water while it is still wet, every time — not at the end of the trip.
BALANCE IS REAL AND IS OVERSTATED. A reel that makes an outfit feel tip-heavy is tiring over a long day. It is worth a moment's thought and it is not worth a purchase decision on its own.

Where to go next
Where it is used
- Fly fishingIn freshwater trout fishing the reel is mostly a line store; in salt water it is the component the whole outfit depends on. Same class of tackle, completely different job.
- Saltwater fly fishingThis is where the reel stops being a line store. A bonefish takes a hundred metres of backing in seconds, and a smooth sealed drag becomes the most important component in the outfit.

What it works with
- Arbor knotWhere the backing meets the spool. Fly reels have unusually large arbors and unusually thin backing, and this is also the fishing where a fish reaching the arbor is a real prospect rather than a theoretical one.
- Fly linesIn salt the reel stops being a line store and becomes a drag and a backing capacity, because the fish run further than a hand can control.

Arbor knot
An arrangement joined to the knot that actually builds it, written where the knot is characteristic of that arrangement rather than merely possible in it. This is the edge a reader travels: they arrive looking for the arrangement and need the connection it depends on.

Understanding it
- How a fishing reel worksA fly reel plays no part in the cast and the whole part in a run, which is worth seeing against the other two layouts rather than in isolation.
- Presentation and dragLine control is done with the hand for most of fly fishing, and with the reel only when a fish has run past the line on the water.
- What salt water does to fly tackleThe reel is the fly component salt attacks hardest, because it is the one that gets immersed and the one whose drag does real work under load.
- Why fly tackle is built the way it isWhy the reel sits behind the hand, why it is often a line store, and why in salt water it becomes the most important component.

How a fishing reel works
A mechanism edge from a record to the explanation beneath it. How tackle behaves is established practitioner knowledge reported consistently across independent traditions, and the label says that rather than claiming a test that was never run.
