Strong Arm Crab – The Permit Slayer
When it comes to fooling permit, few flies have earned their place like the Strong Arm Merkin Crab. Designed by seasoned flats guide Dave Skok, this pattern combines realism, movement, and balance to create one of the most effective crab imitations ever tied.
With its wide profile, lifelike materials, and signature “strong arm” claws that kick and twitch on the strip, this fly mimics a fleeing crab perfectly. The weighted eyes ensure it rides hook-up and lands softly—ideal for sight-fishing spooky fish on shallow flats.
Why You'll Love It:
- Proven permit and bonefish pattern with lifelike crab profile
- Signature “strong arm” claws provide subtle movement and realism
- Rides hook point up to avoid snags and improve hook sets
- Weighted for accurate casts and perfect bottom presentation
- Tied in fishy, natural colorways for tropical waters
Whether you're targeting permit in Belize or redfish on a muddy flat, the Strong Arm Crab is a confidence fly that’s ready to convert your next shot into a hook-up. Don’t hit the flats without it.
This pattern is also available in an assortment here.
