Science is in our nature. Our latest innovation
is the Sharkskin technology, a fly line that is
revolutionizing the sport. Some say it does
for fly lines what graphite did for fly rods, but
you should check it out and see for yourself
if all the talk is true.
With cutting-edge angling technology
that is revolutionizing the sport, the
Sharkskin Series provides the ultimate
casting experience.
Sharkskin allows you to cast further with
less effort and with less line tangling —
elevating your fly fishing experience to a
whole new level.
Featuring 3M’s proprietary microreplication
technology, Sharkskin is a radical modification
of typically smooth-surfaced fly lines. Its micro
textured surface provides superior shootability
and floatation while eliminating line
flash and vastly reducing friction. All of this
comes with the added benefit of increased
durability allowing the line to last up to twice
as long.
This line sits higher in the water offering less
drag, easier mending, roll casting, pick-ups
and less water spray. The floating lines in this
series also feature 3M’s proprietary AST and
Dry Tip Technologies. |
What is Sharkskin?
By modifying the surface of the fly line with a micro-repeating structure, you can achieve surface interface
properties that mimic nature such as the ability of insects to walk on water, the shedding and self-cleaning ability of Lotus leaves, or the adhesion that allows a gecko to walk up vertical surfaces.
Scientific Anglers Sharkskin technology is a precise texturing process that embosses the surface of the fly line
coating with a repeating geometric micro-pattern. The finished surface is no longer smooth, no longer exhibits
unwanted line flash, and can be optimized via the engineered shape, depth, and frequency of the pattern to yield greatly improved line-to-water floatation, casting performance, and overall line suppleness and durability.
What is the specific benefit for a floating fly line?
The Sharkskin technology is a radical modification of typical smooth-surfaced fly lines…introducing a micropattern
around the entire circumference of the line. One of the pattern’s key features is that it changes the meniscus force balance that up until now, holds all other floating fly lines at close to a neutral buoyancy within the line-water interface…essentially ½ the line is above the surface and ½ the line is below the surface. The micro
texture greatly increases the upward meniscus force through a combination of the water’s interaction with the new surface and the trapping of air into the valleys of the texture. The result is an over 200% improvement in
resistance of the line to be forced into the water….effectively improving “floatation” of the line significantly beyond anything that can be achieved through the addition of glass bubbles or surface chemistries. The line sits higher in the water – less drag, easier mending, easier roll casting, easier pick-ups, less water spray.
What are the benefits of Sharkskin on casting?
Simply reducing running line diameters on weight forward (WF) lines has long been utilized as a way to reduce line
friction in rod guides. However, reducing line diameter also reduces line durability, and increases the propensity
for a line to tangle. Simple texturing of a fly line reduces the surface contact with rod guides during casting.
Scientific Anglers introduced the Bonefish taper and other key distance-casting lines that utilize a braided
monofilament core - modifying the surface of the running line, reducing the frictional interface during casting and
resulting in the ability to shoot farther but with few tangles. The Sharkskin technology takes this a step further, allowing lines not made on stiff braided monofilament to have this shooting and casting advantage and the advantage extends to the belly and tip of the line, not just the running line.
Because friction in the guides is reduced significantly, even when the line belly is in the guides, shoot distance is
increased allowing longer, easier casts. Casters who also double haul find haul resistance reduced which results
in easier, smoother hauls, even on hot days or when the line is dirty. This, along with reduced shoot friction, has
resulted in increased test casting distance when compared to the exact same line without the Sharkskin texture.
Distance increases compared to competitive lines without the advantages of AST, Sharkskin, and our new taper,
will be significantly greater. Although these new lines excel at distance, the features that allow that distance make shorter casts even easier.
What other features are improved with Sharkskin?
Another advantage of this new technology is complete elimination of line “flash”. Most other lines have slick, glossy surfaces that reflect light and can “flash” in the air scaring spooky fish. The micro-texturing process virtually eliminates surface glare, the finish is completely flat. When conditions are such that line flash is an issue, Sharkskin lines have an additional advantage over other lines.
One would expect this radical change to the line to diminish the coating integrity and resistance to cracking. Actually, the opposite occurs. The engineered micro-repeating pattern effectively introduces flex points that increase the suppleness of the line and in lab testing, the durability and resistance to cracking is up to 3X greater. A good analogy is how a bicycle chain, although made of metal, bends due to flex points in the links. |
