Roll it up, let it land, then one smooth peel off the surface. The water's grip loads the rod for you — no false casting, and slow everything down: dense lines carry speed.
Line management
The water haul: casting sinking lines
Draft reference — pending review.
What it's for
You cannot lift a sunk line into a backcast — it's under the water, not on it. The water haul uses the surface's grip on the line to load the rod: roll the line up to the top, let it land straight, then use that tension for one smooth delivery. Safer for you and your boat partner, and kinder to the rod.
The beats
Roll it up
Retrieve until the sink-tip or head is within range, then roll cast the whole lot up and forward so it lands on the surface, straight in front of you.
Let it land
Let the line touch down and sit for a beat. That surface tension is your casting weight — don't snatch it off.
Pin and sweep
One smooth, accelerating backcast straight off the water — the line peels off under tension and loads the rod deeply. No false casting; a dense line carries speed a floater never will.
One shot
Deliver on the very next forward stroke, slightly open loop, and let it shoot. Slow everything down — thin, dense lines generate more line speed for the same effort.
Common faults
Ripping the sunk line off
The rod jars, the line comes up in a heavy spray mid-cast, the cast dies — or three metres of Di5 and two flies come past your ear.
Fix: Always roll the line to the surface first. If the lift still feels heavy, you've too much line out — strip another two metres before the roll.
When you'll use it
- Any sinking or fast-intermediate line, boat or bank
- Boobies and heavy lures on Di7/Di8 — the payload that punishes a normal overhead most
- Tired arms: the water haul does the loading your double haul would have done
