Trolling
THE ART OF TROLLING SKIRTED LURES
Peter Pakula
Trolling skirted lures through
the ocean in search of pelagic fish ranging from small tuna to Godzilla
sized marlin is easier in essence than just about any other form of
fishing. The technology in electronics, rods, reels and harnesses, plus
their relatively inexpensive prices has even made small boat, even as
small as 12 foot (There is an 8’ game boat in Kona, appropriately
named “Brain Damaged”, though I certainly don’t recommend boats
that small!!!) viable platforms to hunt these fish on an even footing
with the large Game Fishing battle wagons, though indeed the larger
boats are certainly more comfortable and handle rougher seas with more
comfort and safety.
There are few things on this
planet that give as good an adrenaline rush as witnessing a rising
dorsal accelerating to intercept a surface run lure. Without exception
the take, and the moments following a strike are awe-inspiring and
totally addictive.
As with all forms of fishing the
starting point is rather technical, learning how the gear works on its
own and interacts with the other equipment is essentially a technical
exercise. Only when that has been understood and using it becomes second
nature can you effectively start enjoying the art of lure trolling.
Somewhere on the planet a season
is just ending and another just starting, anglers may have cracked their
first successes, or they are just about to. The conditions and currents
might have something to do with this,
though I suspect that many of the
marlin captures are a direct result of anglers having a better
understanding of the workings of the ocean and skills of trolling
artificial lures.
It is, at long last, accepted
that artificial lures are not only an effective weapon for catching
large game fish and the most spectacular of all. In many cases it is the
most effective, being responsible for many wins against those using
other methods. The best news is that trolling lures is very easy to do.
Indeed a novice can be very competitive with just a basic knowledge of
lure trolling.
Those who consistently miss out
on success may do so for a many number of reasons, not the least of
which is sheer bad luck. Though I suspect the main reason for failure is
because of a misunderstanding of basic lure trolling principles that
significantly decreases the chance of reasonable success.
Anglers generally experience
some form of trolling before using skirted trolling lures for game fish.
It might be trolling for trout along weed beds and drop-offs in a lake,
or trolling around the edge of the sandbanks, circling schools of small
pelagic fish or trolling for kingfish and small tuna along rocky shores
and reefs.
These forms of trolling have
many things in common. They all involve relatively low trolling speeds,
under five knots, and often at a slow walking pace. Lures are placed a
long way behind the boat so the lures will be in the ‘zone of
convergence’ that is, the distance behind a moving boat where
disturbed fish converge and resume normal behavior and hopefully, resume
feeding. In most of these types of trolling it is assumed that the boat
scares the fish. (In most cases in all forms of trolling this assumption
is incorrect, however the assumption remains ingrained
Unfortunately these types of
trolling have nothing whatever to do with trolling for large oceanic
game fish. In fact, it’s generally just the opposite. When converting
to blue water trolling, you have to abandon the idea that the lures
should be as far away from the boat and its wash as possible. When
trolling for the big game fish, the boat and it’s wash are actually
part of the system and the trick is learning how to use it to your
advantage.
THE MOVING
F.A.D.
When using skirted lures, the biggest difference is the speed. In blue
water skirted lures are pulled along at effective speeds from a minimum
of 6.5 knots, mostly 7.5 to 8.5 and as fast as 15 knots with the
accompanying noise, vibration and white water. These components actually
combine to form an effective ‘Fish Attracting Device’.
Many anglers, because of their
previous experience with other forms of trolling, run their lures way
back out past the end of the wash, fearing that the boat noise and wash
will scare the fish. In this form of fishing this is not the case. The
action is concentrated in the area between the transom and the end of
the prop wash and turbulence. This is known as the Strike Zone. This
area is where you should run your lures.
Indeed fish do get hooked on
lures a long way back, but they were probably on their way to the boat.
The chance of getting a solid hookup on a fish are far better on a short
line, due to less line stretch and belly.
It is possible that the wash
itself may appear to be a shoal of tiny baitfish foaming the surface in
a feeding frenzy, or perhaps they have come to know that the motor noise
and vibration could mean a trawler dumping trash over the side resulting
in an easy meal, perhaps it does attract small predators like striped
tuna and frigate mackerel that search the white water for a feed or
camouflage, this may in turn attract larger predators. Regardless of
what we imagine the wash represents to fish the boat does not in any way
scare these predators. The larger, bolder predators have even less fear
and will come in so close to the transom they almost ram it as if they
were attracted to it.
READING THE
WASH
Before we put the lures out, let’s slow down to an average trolling
speed of about 7 knots and have a look at the Strike Zone, the area
between the transom and the end of the prop wash or turbulence created
by the boat hull. You can read the wash behind a boat in a similar
manner to reading the water around a headland, island, reef or beach.
The features of the wash are
shown in the adjacent figure.
(Fig 1. Reading the Wash)
Down the center is the prop wash, a very
concentrated boiling confusion of white water, or so it
seems. This
white water is at its deepest at the transom, with the maximum depth at
the props. Perhaps it is not as deep as you might have imagined, and
comes very close to the surface within a few feet of the props. Although
it looks like solid white water, it is quite translucent, allowing
enough light to enable even small tuna to find tiny lures in the midst
of it.
Along the side of the prop wash
there are alleys of clearer water with little or no white water
turbulence; a nice place to run a lure, as it would be very visible.
Remember though that predators are used to chasing tiny baitfish that
are very well camouflaged. No matter what size or colour your lure is,
it will show up very clearly no matter where you run it, as will your
leaders and rigging.
Notice the white water coming
off the sides of the boat. This Side Wash is very shallow and almost
transparent consisting mostly of surface bubbles. A lure that is run in
this area is probably more visible than in any other area, as the frothy
white surface will highlight the lure’s silhouette.
Every boat has a different wash
format at every speed, in every sea condition and in every direction
traveled.
For example the wash is longer going into a current than it is going
with it. To maintain the lures position you may lengthen a lures
distance going into the current and shorten it going down current.
THE WINDOW
The next items to take note of in the Strike Zone are the waves following
the boat. These are pressure waves kicked up by the boat and vary in
size depending on the boat size and hull type. The distance between them
is the waterline length of the boat. These waves are the most important
part of the wash for trolling skirted lures, as they are run and
carefully positioned or tuned on the leading face of the pressure wave.
On close examination you’ll
note several things including:
They are largest at the transom and gradually get smaller further back
in the wash and generally fade out around the end of the prop wash and
turbulence. The top of the wave is steeper than the bottom of the wave.
The face of the wave is far more visible from behind than the
back of the wave. We’ll call this the ‘window’ as shown in the
adjacent figure.
(Fig 2. The Window) The further down the face of
the wave, the larger the ‘window’ and the more visible the lure is.
It is important to note that
some boats don’t have pressure waves, in which case the positioning of
lures is less critical. It is also important to note that the rougher
and choppier the sea the harder it is to distinguish where the pressure
waves are, though with a little experience you will get to know how
properly set lures appear and behave and position them accordingly.
WHAT A LURE IS
Until we can interview a game fish we really
don’t know why lures do catch fish. However over the years we have
come to understand why some lures consistently catch more fish than
others. It appears that they work because they trigger feeding and, or
aggression responses. Basically in the world of the predator anything
that moves and easily caught is possibly edible, the more like something
it’s used to eating and the sicker or more wounded it appears the more
likely a predator will commit its precious energy resource to an attack.
This is a natural hunting response. A cat will attack anything that
comes within range. A child will try and catch anything that is thrown
towards it. The factors that contribute to the effectiveness of a lure
are size, shape, colour, vibration, action, rigging and of course, but
often overlooked fact of, using them in an area likely to produce
results.
WHAT A LURE
DOES
The types of lure we are specifically discussing are surface running
skirted trolling lures. (Though much of the theory has relevance to
other types of lures and forms of fishing). When run behind the boat,
trolled, they tend to ‘work’ in a repetitive cycle. A lure that is
working properly runs through the following cycle: It comes to the
surface, grabs air ‘breathing’, dives down leaving a long bubble trail,
‘smoking’ and when it stops smoking, it comes up for another breath. It
should not run under the water without a smoke trail for any length of
time, if it does; it is called ‘lazy’. Also, it shouldn’t come out of
the water, ‘blowing out’ when breathing.
All the different shapes and
sizes go through these motions with different aggressions and timing.
For example, for many sliced headed lures the cycle is repeated every 15
seconds, some as long as 30 between breaths, Pakula lures are at their
best when they breathe every 5 seconds. Some lures come to surface and
softly breathe before diving, others explode on the surface causing a
sonic boom. Some dive as straight as an arrow, others may ‘swim’ off
the side or dive in deep consistent arc, others shake their heads or
tails as they dive. Smoke trails vary from pencil thin to almost
creating their own prop wash. This mainly depends on the shape of the
lure head, lure length and trolling speed. How often a lure goes through
the working cycle depends on sea conditions, boat speed, lure position,
line class and rigging.
LURE THEORY
Now that we understand the basic idea of where our lures
are to be run and what they are supposed to do we can now move onto the
lure selection. This is generally based on the level of information
you’ve got, varying from getting a set of lures recommended by your
local tackle store or from anglers fishing in the same areas, or perhaps
chosen by recommendations from manufacturers, web forums, and indeed
from personal preferences based on your own experiences.
Care should be taken if you
incorporate individual lure recommendations to form a lure pattern.
Think of it as getting advice for car parts, you could end up with an
economical 1200cc motor, 4wd diffs, balloon tyres, comfortable LTD body
etc, all great as separate items but when they’re put together it’s
a bit of a disaster.
When
choosing lures we tend to specify them according to the species of fish
we most desire to catch, such as Blue Marlin Lures, Sailfish Lures, Tuna
Lures, Wahoo Lures etc. Unfortunately this method of classification is
not only incorrect, it is often misleading.
A lure pattern should imitate a
selection of wounded or fleeing bait species that are likely to be in
the area at the time you’re fishing. As most predators will feed on
any available food source over any given period, if you get this right
and you’ll target whatever predatory species are around from small
tuna to monster billfish.
“Matching the hatch” is actually quite easy, as the species of blue
water bait are very similar throughout the world’s game fishing areas,
though it is very important to note that the food types change as they
migrate through an area at certain times of the year. By following this
system through you’ll also notice that through any given period there
are many available food species. By working out which food is most
likely to be in the area you can more accurately select a lure that
“matches the hatch” in action, colour and size. There is no doubt
that if you get this system right you’ll even catch the fish you’re
after out side the period considered to be a normal season.
NB: There may also be an argument for trolling a pattern of identical
lures if you think that there is only one dominant bait species that you
can imitate it successfully.)
SELECTING LURES FOR THE PATTERN
There are several considerations
in choosing lures to form a pattern:
Number of Lures
The next step is to decide how many lures you wish to run and the line
classes involved. The number of lures run varies greatly. In areas where
the fish are in great numbers, or there is a small crew to handle the
gear the number of lures is less than in areas where there are less fish
or more crew on board to handle the gear. For example in Cairns many
boats troll only two lures and no teasers. In other areas up to ten
lures and a brace of up to six teasers are used. In the following
we’ll assume that we’ll use five rods which is not too many for an
amateur crew of three or four to handle if you hook up to a hot fish.
Size
Each
line class has a maximum sized lure that can be effectively trolled due
to the drag setting used. There is however no minimum sized lure for any
line class. Nor is there any minimum sized lure for any species or size
of fish you are chasing. Granders have and will eat lures as small as
five inches long, however as they are rarely rigged to catch fish of
this size they are normally lost on smaller lures. As a guideline most
predatory fish, particularly billfish can swallow a meal of twenty
percent of their own weight. The largest lures that are readily
available are eighteen inches long that is equivalent to a bait of
around four to six pound, so even the largest lure you’ll use is not
out of the question for a small sixty pound marlin.
As
discussed earlier the Strike Zone is from the back of the boat to the
end of the wash or turbulence. To enhance this we select lures from
highly aggressive and large near the back of the boat to more sedate and
smaller as we get to the end of the prop wash which is also the end of
the strike zone. The greater the range of sizes used the more species of
fish you are likely to target. For example a five lure spread would
consist of one fourteen inch, one twelve inch, two ten inch and an eight
inch lure. There may be times when you may wish to eliminate smaller
species such as Skipjack or Bonito, in which case you wouldn’t run
lures under eight inches.(Fig
1. Reading the Wash)
Shape
The chosen set of lures should be compatible with each other in action,
vibration and effective trolling speed. The simplest way to do this is
run lures that are all similar in type, i.e. all Scoop Faced Chuggers
such as the Pakula Range, or all Sliced Head Lures such as Black Barts
and Hollowpoints. Mixing lures types when your just starting out is
really making the sport far more difficult and unsuccessful than it
could be. Each lure developer designs their lures to run in specific
positions within a pattern. Knowing where this position is just by
looking at the lure without a great deal of experience can be quite
difficult.
To make things more difficult the standard terminology used to describe
the lures position ie long corner etc is not appropriate, as it does not
convey the relevant information. Whether a lure works in a certain
position in a pattern relative to the others depends to great extent on
the angle at which the lure hits the water. As shown in the figures
below they vary considerably.
