The First Question; What
Kind of Paddling Do You Plan?
The
most important criteria for selecting a kayak is to pick one suitable
for the type of water you'll be paddling.
There are three basic types of paddling waters with boat characteristics
typical to each type, though there are a lot of subcategories also.
There are exceptions to the characteristics
listed, but these are the basic and typical ones. (You'll
find paddlers have many varying opinions and are not shy about sharing
them.)
3 Basic
Types of Paddling Waters and Boats
Type
of Paddling Waters
|
Typical
Kayak Characteristics
|
Whitewater
Fast-flowing streams with
obstacles and quickly changing currents
Surf
kayaks are a
variation designed for surfing that are
usually sit-on-top foam-filled hulls with fiberglass skins
much like surf boards.
e.g. rivers and creeks with
rapids, waterfalls and substantial and changing drops in
altitude over short distances
NOTE: There's a standard
scale to describe the intensity and dangers of paddling waters
by rating on a scale of 1 (flatwater) to 6 (extremely dangerous
whitewater). You may find this scale on KayakGuide.com or
books about paddling. Always remember however, that changes
in weather can also change the rating and danger of any water
body quickly.

in wind and waves
Typical
lengths from 16' to 22'
Faster

For
each of these three basic types of paddling, there are both recreational
and high performance "competition"
kayaks made of more exotic (and more expensive) materials to reduce
weight and more extreme shapes and dimensions for higher skill paddlers.
Sit-On-Top versus Sit-Inside a
Cockpit
Personal preference comes to play
in deciding between sit-on-top and sit-inside, but I'll share my
thoughts.
For whitewater or long distance paddling,
I prefer to sit inside a cockpit to protect myself from elements
or from rocks, trees, and other obstacles that can hit me in whitewater.
For
moderate weather flatwater and even mild whitewater (e.g. Class 2),
I prefer quality sit-on-tops for the
following reasons:
-
Easier entry and exit into the boat, which I use frequently to fish,
explore shorelines or portage
- Easier reentry and exit into the
boat in deep water, which I do to snorkel or swim
-
For SCUBA diving, some sit-on-tops offer decks designed to hold tanks
and gear securely, yet accessibly
-
For fishing, most sit-on-top kayaks are more suitable to mount
rod holders and keep tackle readily
accessible
- No need to empty the boat in deep
water; if water gets on deck it drains out through holes
- Exit boat quickly and easily if
capsized in shallow surf to help avoid a face plant on the bottom.
My all around favorite kayak is a
Current Designs Kestrel sit-on-top, a versatile, lightweight 14'
Kevlar hull, fiberglass deck with good internal cargo space and solid
performance. I also liked my 16' Heritage Nomad fiberglass sit-on-top
for calm flatwater, but sadly it is no longer made in the lightweight
fiberglass.
There are a couple of tradeoffs with
paddling sit-on-tops however. In open water on a sunny day, use sunscreen
or pants and shoes to protect your lower body from the sun. And if
you're paddling creeks and swamps with lots of tree branches you
may get scratched more than you would sitting inside a cockpit. In
cold water or weather, I always wear a wetsuit or drysuit for safety
in case I go in, so that's not a factor for me with either sit-inside
or sit-on-top boats. Some people think they can avoid wearing protection
from cold water by sitting inside a boat instead of on top. But I
don't think that's a safe practice because water can get inside or
the paddler might have to exit the boat in cold water.
If
you're buying your first boat, please read further in this article
about "Dimensions and Shape" and "Weight" because
there are many sit-on-top models sold that are too short (too slow),
too wide (too slow) or too heavy. Many of these boats are sold to
beginners playing on the typical fear that they are more likely to
be trapped inside a cockpit if they flip or that they need an excessively
wide boat for stability. The bottom line is that a boat that does
not perform well is not a safer boat in the long run.
Dimensions and Shape
Very
frequently I've observed that people new to paddling buy a boat that
is too flat on the bottom or too wide because they are too afraid
of "tippier" boats
with more rounded or narrower bottoms. Because such boats are slower,
they quickly regret their choice when they find themselves falling
behind
other
paddlers
and
getting
exhausted
paddling harder than those with faster boats.
The
length, width (also called the "beam"),
and hull shape all determine how easily the boat turns, how quickly
it paddles through the water and how stable it is on the water. The
table below explains how different characteristics affect kayak performance
and provide general guidelines on what we consider to be effective
dimensions in some cases.
Overview
Guidelines on Kayak Dimensions and Shape
Hull Characteristic
|
Effect
and Guidelines
|
Length
The
key dimension is the "waterline
length"; the length of the hull normally at the surface of
the water with a given weight paddler on board.
|
The
longer the boat hull, the faster it is.
Because kayaks move through
the water by displacing water around them, a kayaks top "hull
speed" is determined by it's waterline length. (Paddling
any faster than the hull speed is very inefficient and very
tiresome.)
|
Width
or "beam"
The
key dimension is the "waterline
beam"; the width of the hull normally at the surface of the
water with a given weight paddler on board. However, a beam
that is not normally in contact with the water may contact
the water if there are waves, thereby slowing the boat down
in rough conditions.
|
The
narrower the boat hull, the faster it is.
The
wider the boat hull the more stable it is
But
the shape of the hull across the bottom from side to side
also determines stability
I prefer no flatwater or
sea kayak wider than 26" in overall beam or it feels too
slow and hard to paddle.
|
Volume
The longer, wider and more
bulbous shape (fat) the boat, the larger volume of air it
holds and the heavier a load it can carry (weight of paddler
and gear).
|
Heavier
paddlers need to make sure the boat they buy is rated to
carry their weight
or they'll sit too low in the water.
Volume
is also especially important to whitewater boats, which are
sized not only by
length and width models but also by volume within a model.
This is because whitewater boat maneuverability and stability
can be affected significantly if it floats too high or too
low for a given paddler weight.
|
Rocker; hull curve fore
and aft (from front to rear)
The
cucumber and the banana
If you place a straight cucumber
on a table and try to turn it, it resists. But if you hold
a banana upright on a table like a kayak, it turns easily
since it only contacts the table at one point in the center.
Kayak hull rocker is the same idea.
|
The
more curve in the bottom of the hull from the front of the
boat to the rear of the
boat, the more easily it turns; like the banana on the table.
The
less curve in the hull over the length of the boat from front
to rear, the more
efficiently it will track and paddle in a straight line through
the water.
|
Stability; hull curvature
side to side
Aside from the width, the
hull shape also affects how stable it is.
Secondary Stability means
that the hull shape changes stability as the kayak tilts
more e.g. Heritage Nomad had a section of hull that normally
only made contact with the water when the boat tilted, serving
to help keep it from tilting any further. This had the advantage
of keeping the hull normally in contact with the water narrow
and fast while still providing "secondary stability".
|
Looking
across the bottom of a hull, a flat shape (or even catamaran
hull) gives the
most stability.
A
more rounded hull is faster since it has less contact area
with the water to carry
the same weight.
A
more rounded hull is usually easier to turn as well, especially
with more advanced
turns tilting the kayak up on one side.
Some
hulls are designed to provide more stability as the boat
tilts more. There are
tradeoffs and paddlers should try a boat for some time and
distance to get a feel for its performance.
|
Weight
Don't
overlook the weight of a boat. Not because less weight does make
a boat faster, but because if you
like paddling, you'll want to transport your boat to new Places to
Paddle. So you'll need to lift it onto your vehicle or trailer and
then carry it from the vehicle to the entry point on the water. Can
you say hernia!
For myself, I prefer that a
flatwater kayak weigh no more than 40 pounds.
Weight is determined by two things;
size and material. Unfortunately, for a larger, higher performance
flatwater or sea kayak, you'll have to pay more for lighter materials.
There are now lighter plastics however, with the weight of fiberglass
that are cheaper. The most expensive and lightest boats are kevlar
or carbon fiber.
Collapsible Kayaks
Sometimes there's nothing quite as
nice as being able to take your own boat with you in a duffel bag
when you travel. Collapsible kayaks offer that capability. The tradeoffs
are usually the amount of time and effort to assemble or repack the
boat, more money and some performance compromise. Though with many
contemporary models, the performance of modern collapsibles is as
good as many high-performance regular kayaks.
There are cheap inflatable kayaks
sold that are not as durable as others and are much slower. I would
avoid these.
There are three basic types of collapsible
kayaks.
3 Basic
Types of Collapsible Kayaks
Collapsible Kayak Type
|
Typical
Characteristics
|
Inflatable
These typically have multiple
air chambers to provide flotation in case one leaks, though
the boat may not be navigable with a deflated chamber. Better
inflatables have air bladders that tension against a low-stretch
fabric shell to stiffen the hull when the bladders inflate
and tighten against it.

|
Easy
and fast assembly and repacking in as little as 10 minutes
Somewhat
slower to paddle straight
More
suitable for flowing streams or shorter distances
Materials
range from durable composite fabrics to cheap flimsy PVC
Flotation
from multiple air chambers in case of a leak
Typically
sit-on-top or canoe designs, though there are a few sit-inside
designs
that even take spray skirts
|
Skin-On-Frame
These are typically wood,
aluminum or synthetic material sectional rigid frame whose
pieces are assembled into a basic hull shape inside a strong,
low-stretch kayak skin. Levers expand the assembled frame
to provide tension that stiffens the hull into a high-performance
shape.
|
Assembly
time ranges from 15 minutes to over an hour
High
performance, light weight designs exist at a price
Aluminum
frames require cleaning and lubrication to prevent oxidation
and ease assembly.
Sand
and grit must be washed from the frame and skin to prevent
wear especially at joints
and stress points.
Flotation
must be added for safety.
|
Hybrid
These are simpler assembled
frames that are tensioned by inflating air bladders in a
taut synthetic skin.
|
Assembly
time as low as 15 minutes is almost as quick as inflatables
Good
performance, light weight designs exist at a price
Flotation
from multiple air chambers in case of a leak
Typically
sit-on-top design
|
Innova, Feathercraft and Folbot are
well established, reputable brands building excellent collapsible
kayaks. My favorite hybrid collapsible is a Feathercraft Java, a
versatile 16' that can be assembled as either a single or a double
in 15 to 20 minutes.
Options
and Accessories
There
are many special adaptations of kayaks.
A
couple of the most common accessories are removable skegs that help
boats track better to maintain course without a lot of extra paddling
effort, especially in wind. But skegs can become annoying in shallow
water, so some
boats
have
skegs
that
are
retractable
by
the paddler from the cockpit. Similarly, rudders can make for more
efficient control of the boat, especially in the wind or when fishing
or taking photographs with both hands.
For
fishing, I
have a sit-on-top fitted with a rod holder in the console
between my knees that makes
it ideal for trolling a line over my head while paddling;
a great way to catch trout. Other fishing accessories include a
variety of
stabilizing floats that can be deployed to allow the paddler
to stand and cast
in deep water, trolling motors, bait wells, catch wells, and
tackle
holders.
Others
fit navigational aids such as compasses or GPS mounts on their boats.
And
of course there are a variety of water resistant hatches, straps,
netting or brackets to hold everything from camping gear and food
and water to your paddle so you can take photographs or fish with
both hands.
The
latest gadget mounts are for waterproof
high-definition video cameras like the excellent Contour GPS.
For
paddlers that also like sailing, there are a variety of sailing and
kite rigs that can let the wind propel your boat under the
right
conditions. There are more popular with sea kayakers that have long
distances to paddle in sea breezes over unobstructed open water.
One
of the best things I saw for paddling in hot sun was a
cleverly designed, rear-mounted bimini shade that could be deployed
or stowed by the paddler on the
water, but I have not seen it sold in years now.
Because
paddlers
enjoy finding new uses for their boats, the variety of accessories
and customization will never end.
A Few Final Thoughts
There
are other factors to consider, but I don't want to over-complicate
things, so I'll just mention
a few I think should be considered.
Repairability may be important to
you. You may want to research how repairable a kayak material is
and how costly the repair. Fiberglass can be repaired by a handy
paddler with no outward sign of the repair left. Some plastics are
almost impossible to repair in an invisible manner. For example,
polyethylene plastic usually requires welding by a professional with
the right equipment, material and skill. But fortunately, polyethylene
is a tough, heavy material that's less likely to need repairs (unless
it's been exposed to the sun too long which makes it brittle).
The most important final thought
is to try out the boat for enough time to know how it performs. A
day paddle with a group is best since you can gauge how it paddles
relative to others. Don't take a 5 minute paddle and make up your
mind on a boat; it's not enough time.
Talk to other paddlers that own the
boat. And read internet search results and unbiased reviews.
