Choosing a Kayak for Fishing
Kayaks come in all shapes and sizes but a few particular
styles work well for kayak fishing. Kayaks were first developed
in the northern regions around the Arctic Ocean, the Bearing
Sea and the North Pacific and Atlantic Oceans. Inuit people
used them as transportation of people or materials, hunting
and fishing and even racing. Several designs emerged with
boats having two or three cockpits and ranging from 17'
to 60' in length. Constructed from wood and animal skins
there were typically multiple paddlers using single-blade
paddles. The designs from major manufacturers today differ
very little in many areas.
In brief here are a few of the different styles of kayaks
out on the market.
1. Sea Kayaks - typically long, narrow
and lightweight these kayaks are designed for one or two
paddlers. The length of these boats is geared towards long
paddles in open waters that don't require great maneuverability.
The longer water lines of these boats makes them better
at tracking a straight line and doing it quickly. Typically
made of fiberglass there are now models made from carbon
fiber or even kevlar. Not very well suited for fishing
as they are what are known as sit-inside kayaks where you
are litterally down inside the boat with little deck space
for storage of gear.
2. Surf Kayaks - These are similar to
a whitewater kayak with a few changes to their hull shape
to provide more control when on the face of a wave. Typically
on the shorter side (8'-13') they do exactly what the name
suggests - carve waves. Another relative of the surf kayak
is the surfski. The surfski is crazy long at 20+ feet and
usually around 18 inches narrow. Born out of Australia
as surf racing kayaks they're also popular now in the US
as flatwater racers.
3. Whitewater Kayaks - These are the
kayaks you see most often on TV or in commercials. Some
lunatic wearing a helmet sits in a 9' coffin and bounces
off rocks and barrels over waterfalls. Usually made of
tough polyethylene plastic to withstand the beatings a
river can give they range in size from five and a half
feet to ten feet in length. These are also a sit-inside
style with the paddler wearing a spray skirt to keep water
out of the cockpit.
4. Inflatable Kayaks - If you need to
be able to put your kayak in a bag and carry it around
this is your choice. They're inflatable by any number of
methods but most come with a foot pump. They have multiple
chambers to inflate for safety reasons and use very little
air pressure, around 3 pounds per square inch (PSI). Some
new kayaks from companies like Seyvlor are now featuring
rigid frames for additional support. Design-wise they most
resemble sit-on-top kayaks.
5. Sit-on-top Kayaks - Angler's first choice. The
rotomolded (rotational molding) version of the sit-on-top
(fiberglass and other materials can be used to create one
but roto is most common) are designed to be an unsinkable
bubble of plastic. Large, two-piece molds are bolted together
(top to bottom) with an appropirate amount of superlinear
polyethylene plastic inside. The plastic starts in an almost
powder form that is dyed to achieve kayaks in multiple
colors. The mold is placed inside a giant oven and fired
from the outside with propane or natural gas burners. As
the kayak mold heats up the plastic melts. The oven is
designed to rock back and forth as well as rotate thus
spreading the plastic around and creating the kayak hull.
When the kayak is removed from the mold it is injected
with air to help it keep shape while cooling. Interesting
note about the colors - different dyes will affect the
plastic differently. Red boats shrink more than yellow
by a few inches. Also, some colors require more plastic
and create denser boats.
Here's the meat of it - the rotomolded sit-on-top kayak
is the most common kayak fisherman's choice for many, many
reasons. We will discuss the basics and try to explain
the features most commonly looked for by fishermen making
the move from a float tube, boat or shore into a kayak.
A few basic generalities that impact the performance of
the kayak.
- Length - longer boats generally are faster and will track
(move forward in a straight line) but less agile. Shorter
boats can turn quickly but may prove more difficult to
track over open water. Top speeds are rarely that different
between sit-on-tops because the longer kayaks create more
friction. The advantage most people find isn't a higher
overall speed but that the power it takes to move a longer
or narrower kayak is less.
- Rocker - Kayaks are built with a curvature of the hull
that bends the kayak up at the ends. The greater the rocker
the more serious the curvature. This can counteract some
of the agility problems in a case where a 15' boat only
has 13' of contact with the water because of the rocker.
Rocker also assists kayaks in getting over the swell or
chop and reduces the amount of water taken over the bow
in less than ideal weather conditions.
- Width or Beam - Width of the hull combines
with length to help create the stability and speed profile
of each boat. A 15' foot kayak that is 35 inches wide is
going to be slower than a 15' kayak only 27 inches wide.
Water displacement and is reduced as is friction. All kayaks
will still wobble side-to-side and width plays a part in
creating stability. If the width of the kayak is designed
with bouyancy on the edges, away from the centerline, it
will create more primary stability. This
is typical of kayaks like the Cobra Fish 'n Dive or Hobie
Outback and their reputations for being "rock solid". A
flat bottom will also create primary stability over a v-shaped
hull. The tradeoff for a flat bottom or bouyant edges is
that at the same time they're creating primary stability
they are most likely reducing secondary stability. Secondary
stability is the end-all be-all of keeping your kayak upright.
It provides the ability to lean at an agle into the water
without flipping over by creating a larger cross section
to the water the further they are tipped. A chine effectively
widens the beam of the boat when it's on tilt and creates
more chances for recovery. Over time paddlers tend to migrate
from boats that have great primary and lean to something
with better secondary stability, especially if they fish
in rougher water conditions.
Now that you understand the tradeoffs and benefits of kayak
designs the rest of the decisions you make are going to be
cosmetic and functionality based. Let's get to the good stuff...
