I was down at X Flats a few years back with the wind absolutely honking, and a permit came cruising along the edge. I threw what can only charitably be called a backhand cast — the wind grabbed it, the leader piled, and the fly landed something like eight feet off the fish. I remember thinking, well, that's that. And that permit stopped, turned almost ninety degrees, and bum-rushed the fly.
It didn't eat, and it spooked a second later. But it taught me the thing this whole post is about: fly fishing for permit is not a precision-under-glass exercise. It's about getting the fly close enough, fast enough, that the fish has to physically react to it — a standard lead of about three feet, adjusted constantly for chop, fly weight, and how fast the fish is moving. Then you fish the drop, and you set on what you see, because you will almost never feel the eat.
What This Technique Is (and What Problem It Solves)
Everything a trout angler learns about not spooking fish has to be partly unlearned for permit. Permit are erratic — they move faster than bonefish, they change direction constantly, and a fish that's forty feet away and heading left may be twenty feet away and heading right two seconds later. A cast placed at a polite distance ahead of where you think the fish is going is very often a cast the fish never sees.
So the accepted approach is close to the fish: show it the fly and accept the risk. Damien Nurre, who has spent years managing and guiding the permit fisheries of southern Belize, framed the mentality on Episode 14 as spook them or catch them. Either outcome beats the third one, where you throw three careful casts, the fish hears the line land each time, gets progressively warier, and leaves without ever having seen what you were selling.
How Close Should You Cast to a Permit?
About three feet in front is the working default, but that number moves constantly. On glassy calm water you may need six, ten, even twelve feet or the fly lands like a thrown rock. With a foot of chop you can crowd them to three feet or less. A heavy fly can be placed closer because it drops into the fish's line of sight quickly; a bead-chain fly might need an eight-foot lead just to sink into the zone in time.
Speed matters too. A permit moving fast in a straight line gets a longer lead. A permit that's stopped and tailing — nose down, focused on a small patch of bottom — gets the fly right in front of its face, or a foot past it, so the fly drops down through its line of sight. And a permit swimming away from you, which is nobody's favorite shot, is actually one that permit respond to unusually well: land the fly three or four feet past and off to one side so it comes back across as the fish moves forward.
Step-by-Step Mechanics
- Build the Leader with a Long ButtA common permit setup is three to four feet of stiff hard mono connected to the fly line, then a standard 9ft tapered leader off that. You get the length without losing the power to turn a weighted crab over.
- Know Your Fly's Sink RateBefore you fish it, drop the fly in the water beside the boat and count it to the bottom. You should be able to say, out loud, how long your fly takes to get down — because every lead decision you make all day depends on that number.
- Swim-Test an Unfamiliar CrabDrop it beside the boat and pull it at several speeds. If it spins at any speed, you can't fish it at that speed. Plenty of commercial crabs are tied too light, too stout in the hook, or slightly off-balance, and a fly that doesn't ride true won't get eaten.
- Read the Push CorrectlyA waking permit throws a V off its back — on a big fish the wake can be a couple of feet behind the head. Cast at the wake and you've cast behind the fish.
- Cast Fast, Sidearm, and LowOne or two backcasts, shot low into the wind, unrolling and dropping the last foot rather than pile-driving in. Get comfortable with the backhand cast — it's the same cast with an open stance, released on the other end, and it earns you a huge share of the shots you'd otherwise pass on.
- Let It Drop Into the Cone of VisionTake the slack out, then let the fly dive. This is where the eat usually happens, and it's why the fly's sink rate isn't a trivia question.
- Strip Slow, Then Let It Drop AgainA couple of slow to medium strips to get the fish's attention. If it hasn't eaten and there's depth to work with, let the fly sink again. If the fish starts to turn away, move it and hope it comes back.
- Set on What You See, Not What You FeelA permit eating on the drop rarely registers as pressure. Watch for the fish flaring its front fins, or a kick of the tail. That's the eat. Set then.
- Strip-Set — But Read the TurnRod low, line hand pulling. The one caution: if a good fish has already turned as you set, a long hard pull is how you break off. Come tight, then let the fish do the rest.
- Fight Light Over Structure, Hard in Open WaterOn a rocky or coral flat, back the drag off and let the fish run off the flat rather than grinding your line against something under tension. Follow with the boat, get clear, then crank it down and go to work.
Reading Conditions & Adjusting
Everything gets longer and lighter. Push the lead out to six, ten, or twelve feet and drop to a lighter fly, because on slick water the sound of the fly landing is the whole story.
Crowd them. A foot of chop hides your line and buys you enormous forgiveness — this is when you can put a heavier crab three feet off a fish and get a reaction instead of a departure.
The best shot on the flat and the closest cast you'll make. A tailing permit is a feeding permit, focused straight down at a small patch of bottom, which means you can get close — and means a "safe" cast well out in front is invisible to it.
Permit pushing through three or four feet of water need a fly that gets down through the column fast enough to intercept them. Go heavier, and lengthen the lead so the fly has time to arrive at depth ahead of the fish.
If a heavily weighted crab is wrecking your loops in the wind, drop to something lighter you can actually place. A fly that never reaches the fish accurately catches nothing, regardless of how good it is on paper.
Common Mistakes
Three tidy casts placed well clear of the fish, three landings it heard, three pickups it felt — and it leaves having never seen the fly.
Take the aggressive shot on the first cast. Spook them or catch them. A permit that reacted to your fly is a data point; a permit that quietly left is nothing.
I've done this exact thing — grinding away with a heavy Avalon in wind because it was the "right" permit fly, and putting every cast in the wrong place.
Go lighter. Accuracy is worth more than sink rate on almost every shot, and a fly you can place is a fly that's in the game.
A fly rolling or helicoptering on the retrieve reads as nothing a permit has ever eaten, and you'll never know it's happening because it's happening underwater.
Swim-test every unfamiliar crab beside the boat. Find the speed where it stops riding true, and stay under it — or retire the fly.
You're letting the fly drop, so you're not tight to it. By the time a permit eating on the drop transmits anything up the line, it's already decided the crab was fake.
Watch the fish, not the line. Flared pectoral fins or a tail kick is your cue — set on the visual, and accept that some of those sets will be at nothing.
The fish grabs it coming toward you, you give it a big sweeping pull to come tight, and in that moment it turns. Pop.
Set to come tight, then stop pulling and let the fish load the rod. Permit have relatively soft mouths — you don't need to drive a hook the way you do with tarpon.
Line under heavy tension against coral parts instantly; line under light tension slides across it.
Lighten up and let the fish take you off the flat. Clear the danger with the boat, then tighten the drag and fight it properly in open water.
Author's Story & Key Insights
The trip that reset how I think about permit was a half day in Belize with James Johnson and his father, hunting fish that were pushing hard V-wakes across a bay. Todd was on the bow, and what I remember most isn't the casting — it's how much of the work happened before anyone cast. Those permit would wake for two hundred yards, then the wake would simply vanish as the fish dropped down on a crab, and nobody had any idea where it would pop back up or which way it would be pointed. The whole job was keeping the boat positioned so that when the fish reappeared, the angler had a shot with the wind rather than into it.
That's the part that doesn't show up in permit videos. The cast gets all the attention, but the shot is manufactured well before it — by the guide reading the wake, by the angler having already decided what lead this particular fish gets, and by somebody having tested the fly beside the boat that morning. If you want to catch permit and you only have a week a year to do it, the highest-leverage practice isn't distance. It's the backhand cast and the double haul, so that a fish showing up on your wrong shoulder is still a fish you get to fish to.
EP 14 — Damien Nurre, Belize Permit Fly Fishing Icon Tell All
With Damien Nurre · Fly Fishing Insider Podcast
The permit setup, the crab patterns, and the spook-them-or-catch-them mentality are all covered here. Prefer to listen? The Fly Fishing Insider Podcast is on Apple Podcasts and Spotify.
Put the fly where the fish has to deal with it. I'd rather spook a permit that saw my crab than politely fish over one that never knew I was there — because the fish that reacted told me something I can use on the next one, and the fish that drifted off told me nothing at all.
Terms You'll Hear
- Push (V-Wake)
- The wake a permit throws swimming high in the column. It trails behind the fish's head, sometimes by a couple of feet on a big one.
- Tailing
- A permit feeding nose-down with its tail out of the water — the highest-percentage shot on the flat.
- Cone of Vision
- The zone in front of and above a fish where it can actually see your fly. Getting the fly into it is the whole point of the lead.
- The Drop
- Letting the fly sink freely after the cast or between strips. Most permit eats happen here, and it's why they're so easy to miss.
- Lead
- The distance you place the fly ahead of a moving fish, adjusted for water conditions, fly weight, and the fish's speed.
- Hard Mono
- Stiff monofilament used as a butt section to add leader length without losing the power to turn a weighted crab over.
- Backhand Cast
- The same cast made with an open stance and released on the back cast — essential when wind or fish position puts the shot on your wrong shoulder.
- Permit Alley
- The stretch of Belize flats inside the South Water Caye Marine Reserve, widely considered one of the most consistent permit fisheries in the Caribbean.
Recommended Fly Patterns
Recommended Gear
- Part 1 — Bonefish: seeing the fish, judging the lead, and the shrimp strip.
- Part 2 — Tarpon: the ready position, the 60-20-20 leader, and the first ninety seconds after the eat.
- Part 3 — Permit: accuracy over distance, fishing the drop, and reading an eat you'll never feel. (You're reading it.)
Tight lines, everyone!
Bonefish, tarpon, permit — one trip, three completely different games, and a grand slam that a few people manage in a lifetime. If you're ready to go find out which one humbles you first, let's plan it.
