Royal Wulff Sea Wulff Triangle Taper Mono Clear Intermediate Fly Line – Warm Saltwater
Sea Wulff Triangle Taper Mono Clear Intermediate is built for stealthy saltwater and inshore presentations where you want the line to ride just under the surface without glare or flash. The clear intermediate profile was originally designed for bonefish and tarpon, and it’s also a favorite for stripers on flats and beaches when fish are spooky.
This is a 105’ warm water line (rated 50°F and warmer) with a Triangle Taper Salt design: 30’ head/taper, 10’ handling section, and 65’ running line. Intermediate density sinks about 1.75 ips (Royal Wulff also describes it as 1.25–1.75 ips), keeping crab, shrimp, and other bottom-dwelling species in check.

Deirdre Duncan –
Used this line for bonefish fishing on the flats. The clear color helps the line stay hidden under the surface. The sinking rate is consistent and the line holds up well in saltwater. Great for low-visibility conditions.
Diane Turner –
Fished with stripers on a sandy beach. The line stayed under the surface without flashing, which helped when fish were skittish. The taper design made casting easier and the line didn’t tangle.
Boris Butler –
Perfect for crabbing in shallow waters. The intermediate density sinks smoothly and doesn’t drag. Clear color gives a natural look, and the 105-foot length is sufficient for most inshore trips.
