The Hairy Mary Double Hook Fly is a long established and highly respected pattern in sea trout and summer salmon fishing. Tied on a quality double hook, this version offers improved balance and stability in the current, helping the fly track correctly through deeper pools and steady glides. The added strength of the double hook provides reliable holding power when connected to powerful fresh run fish.
Recognised for its dark body and vivid blue hackle, the Hairy Mary creates a strong underwater silhouette. The contrast between black and blue gives the fly a subtle attractor quality, while the mixed bucktail wing produces natural movement as it swings across the current.
This pattern is particularly effective during low light periods and at dusk, when sea trout begin to move and feed more confidently. Its slim yet lively profile allows it to fish at the correct depth without excessive drag, making it suitable for both rivers and larger spate systems.
NB This fishing fly is barbed.

How To Fish The Hairy Mary Double
Evening Swing
Cast across and slightly downstream and allow the fly to swing naturally through the pool as light fades. Sea trout often respond confidently at dusk.
Controlled Deep Arc
In higher water, fish at an angle and let the fly sweep steadily across the current, maintaining tension throughout the drift.
Introduce Movement
Add short pulls during the swing to make the bucktail flare and the hackle pulse, encouraging reaction takes.
Low Water Salmon
Use during summer conditions when a smaller, balanced profile is needed to tempt salmon in clear flows.
The Hairy Mary Double Hook Fly remains a dependable and traditional sea trout fly, valued for its movement, contrast and consistent performance in both low light and summer river conditions.
