Description
Floating Flotsam Crab – Rainy’s | Size #4
The Floating Flotsam Crab by Rainy’s is a next-generation crab pattern designed for one of the most exciting—and technical—situations in saltwater fly fishing: fish feeding on crabs near the surface.
Built with proprietary 3mm Cross-Link foam, this fly floats naturally and maintains a realistic profile that mimics crabs swimming or drifting in the water column. While traditional crab flies are designed for the bottom, the Flotsam Crab targets a completely different behavior—when permit, redfish, and other predators key in on floating or swimming crabs.
This is not an everyday pattern. But when the moment happens, it’s one of the most effective flies you can have in your box.
Why It Works
• True floating crab profile designed for surface and mid-column feeding
• 3mm Cross-Link foam construction for durability and buoyancy
• Natural drift that mimics swimming or displaced crabs
• Creates a unique presentation most fish rarely see
• Designed for high-visibility, high-opportunity shots
Target Species
• Permit
• Redfish (especially flood tide)
• Bonefish (opportunistic feeders)
• Snook
• Tripletail
• Other surface-feeding saltwater predators
Colors & Conditions
• Tan – Sand flats and clear water
• Olive – Grass flats and darker bottom
• Blue Crab – High contrast / aggressive scenarios
(Based on how crab patterns are selected by bottom type and forage visibility )
