Cast at an angle ahead — the drift brings the boat to your flies. Fan each cast a few degrees round the arc, and stay inside your own quadrant.

What it's for
The heart of lough-style boat fishing. The boat drifts downwind; you cast ahead of it at an angle, and your flies fish round naturally as the boat comes onto them. Fanning each cast around an arc means every drift covers a band of water, not one line through it.
The beats
Set the drift
Boat broadside to the wind, drogue out. The drift line is set by where the boat starts — the features you want are ahead of you, not beside you.
Cast ahead
Cast at an angle ahead of the drift — short, 10 to 15 metres. Not square to the side: the boat overruns a square cast and you're fishing slack.
Fish it round
Retrieve at or a touch faster than the drift so you stay in touch. The flies swing round as the boat closes on them — most takes come as they rise and curve.
Lift and fan on
Ease into the hang, lift off, and place the next cast a few degrees around the arc. Two anglers each fan their own side — bow owns forward of the oars, stern owns aft. Never cast across the middle.
Common faults
Casting square across the drift
Slack line as the boat overruns the flies; missed takes; on a shared boat, your line lands in your partner's water.
Fix: Angle every cast ahead of the drift and stay inside your own 90-degree quadrant. If the boat keeps beating you to the flies, strip faster or shorten the cast.
When you'll use it
- Any drifting-boat day on a lough — this is the default way to fish one
- Sharing a boat: the quadrant rule keeps two lines and four flies apart
- Strong wind: strip faster than the drift or you lose contact entirely
