REVIEW:
The SealLine SmartTrack Rudder System -
Fixed
foot braces with rudder control by Tim Walsh
The nay sayers of rudders in the kayaking world have long argued rudder
systems that require sliding foot braces to control the rudder sacrifice
much needed energy and overall kayak control for the sake of a poorly
executed turn. They have also lamented that rudders, due in part to
their primitive design, create excess drag making for a wearier paddler
at the days end.
The SealLine SmartTrack Control System, a system with solid foot braces
and toe operated rudder control, claims to have remedied those ailments
and created a rudder system that has many advantages over existing systems.
The design, created by Manatee Design, has even won the 2001 Industrial
Design Excellence Award which is sponsored by the Industrial Designers
Society of America, and Business Week magazine.
While fixed foot peg rudders systems have long been the norm in flat
water racing kayaks and some sea kayaks manufactured overseas, this
is the first system, from North America, designed to be retro-fitted
to existing kayaks or as the equipment on new kayaks. When I caught
wind of the opportunity to do a trial installation and operational test,
I jumped at the chance to try something this innovative.
Upon picking up the demo kayak, a Northwest Kayaks Synergy and the SmartTrack
Control System I headed home to tackle the project. As I opened the
box and started pulling out parts and pieces, nightmare visions of the
"assemble it yourself" barbecue grill I tackled last summer
started streaming through my mind.
My fears were quickly extinguished when I discovered all packages were clearly marked and the accompanying packing list provided me a quick check list of the ½ dozen or so components and parts bags.
I was immediately impressed by the fact that each component of the system had its own set of clear, concise instructions including clear graphics and a contact phone number for further information.
Though I was provided with a 12 page "Instruction Notebook" intended for use by Certified Installation Centers, I chose not to use this source of information as I wanted to see if the installation could be performed by the "average backyard mechanic".
The
system is comprised of three major components: the Vertical Adjustment
Plate used to adjust the height of the foot pedal from the bottom of the
kayak and is also a slick way to allow the use of existing foot brace
holes for retro-fit installations; the Toe Pilot Foot Control which includes
the foot brace, associated toe pedal and side rails; the Blade Housing
which includes the rudder and associated hardware. All parts and pieces
appeared to be of stainless steel, plastic or some other material resistant
to the corrosive ocean.
At first I wasn't sure with which end of the kayak to start, but after
spending 15 minutes or so studying the instructions and another 15 minutes
disassembling the existing rudder system I began with the Vertical Adjustment
Plate. The instructions state most people will prefer to have the foot
peg portion of the system 3-4 inches lower than the existing foot bracesto
allow comfortable operation of the Toe Pilot Foot Control. For my size
11 feet, I found about 1 inch lower to be adequate. Using the pre-drilled
holes in the Vertical Adjustment Plate, I simply attached a Pilot Foot
Control and its associated Side Rail to each of the two Vertical Adjustment
Plates, using the supplied hardware, at a height I felt would allow
me to operate the Toe Pilot while resting my feet on the pegs.
I
then attached the combined Vertical Adjustment Plate and Toe Pilot Foot
Control assemblies to the kayak, aligning the pre-drilled holes in the
Vertical Adjustment Plate with the existing holes, from the former foot
peg assembly, in the kayak hull. I was fortunate enough to be using
a kayak where the existing holes in the kayak matched those in the Vertical
Adjustment Plate. One beauty of the SmartTrack Control System is that
existing holes can be used and if they do not match with the Vertical
Adjustment Plate, the needed hole(s) can be drilled in the Vertical
Adjustment plate itself thereby alleviating any stress the "do
it your selfer" may feel about drilling holes in their kayak.
The next step in the process was to install the Blade Housing. At first
the four pages of instructions look a bit intimidating until you realize
that they are written to include the three, most common, existing rudder
installation methods and so only a portion are appropriate for a given
retro-fit. The Synergy had a Rear Mount system with a bracket that is
bolted to the flat stern of the kayak. Removing the existing bracket and
installing the provided SmartTrack bracket was a snap using the existing
holes in the stern of the kayak.
Once
the bracket was mounted, I routed the control cables, which arrive attached
to the Toe Pilot Foot Control, back through the existing cable housing
to the tiller plate on the Blade Housing. To attach the cables to the
tiller bracket I used a nifty device SealLine calls a Cool Rudder Wedge
(CRW) that made the process quite painless compared to other methods I
have seen employed.
In
fact the CRW is itself, a revolution installation of rudders. The trick
to installing the cables was to have someone else sit in the kayak and
operate the Toe Pilot Pedal while I kept the Rudder Housing straight and
they provided feedback as to proper tension. The instructions provided
great insight into the best position (angle) of the Toe Pilot Pedals depending
upon the foot ware the paddler may use. Fine adjustments can be made at
the slide rail on the cockpit end of the system.
The
final steps required installation of the rudder into the Blade Housing
and attaching and routing the rudder cord. Installing the rudder is a
bit tricky, but again the clear instructions made the process go smoothly.
Unlike other rudder systems which require the paddler to give a mighty
heave on one of two cords to deploy the rudder, the SmartTrack uses a
coiled spring, which is imbedded into the rudder, to facilitate deployment
of the rudder. When installing the rudder, a Tension Control Knob is used
to set the correct tension on the spring. The single rudder control line
is connected to the rudder using one overhand knot wedged into a slot
in the rudder. It is then routed through a couple of eyelets on the rear
deck and to a cinch cleat beside the cockpit at a convenient position
for the paddler. The instructions warn that the knot must be flush or
it will interfere with rudder operations. I did find getting the knot
into the slot to be a bit of a hassle even after following the suggestions
provided.
As I stepped back to view the completed installation, I was amazed how,
unlike the barbecue project, there were no extra pieces on the ground,
no multiple trips to the hardware store and during the whole installation
process, only PG language was used. Overall the installation went quite
smoothly and is definitely a project that can be accomplished by the endeavoring
paddler with basic hand tools.
Now that I had the SmartTrack System installed, it was time to take the kayak out on the water and see how well it performed. After all, the proof is in the paddling. Before heading out on the water I considered the different aspects of a rudder system that would be important to the user, contrasted them with the claims of the manufacturer and with the known functionality of rudder systems that have been in existence for some time. I decided to pay particular attention to: ease of operation and control, functionality and performance, and overall durability and reliability.
One
claim of the manufacturer is that the foot braces can be adjusted while
seated in the kayak. Though most kayakers who use the same kayak on
a regular basis usually set the foot braces to a comfortable position
and never move them, the easy adjustment will be beneficial to persons
who get into an unfamiliar kayak and don't get the adjustment quite
right the first time. It will also benefit kayak rental organizations
where there is frequent adjustment of foot braces as clients come and
go. To prove the ease of adjustment, I reached down beside each leg,
grasped the adjustment bar and pulled the each Toe Pilot Control back
one notch. Each assembly slipped back and locked into the next notch
with ease, however the springs that are supposed to hold the Toe Pilots
in their forward position did not seem to do the job and the Toe Pilots
tipped aft. This was easy enough to overcome by pushing the Toe Pilots
back forward, to their appropriate position, with my toes.
When
foot braces were adjusted to a comfortable position, I started to focus
on the systems primary functions, tracking control and turning. Most
existing North American rudder systems require the paddler to push on
a foot peg which is attached via cable to the rudder. The foot peg slides
in a track, pulls the cable, and turns the rudder. The SmartTrack System
uses fixed foot braces on which the paddler can brace his or her feet
and small toe pedals, attached by cables to the rudder, to turn the
rudder. SealLine refers to the toe pedal as Toe Pilots. As I paddled,
I started making turns by pressing the Toe Pilots forward, on the left
or right, to turn the kayak. I was surprised by how little deflection
was required to turn the kayak. Kayakers who are familiar with other
rudder systems may feel the need to "kick" the rudder hard
one direction or the other to attain full deflection; however I did
not find this necessary. To perform extremely sharp turns, I found,
as with all other rudder systems, it more effective to edge the kayak
and use a sweep stroke... with the SmartTrack System the fixed foot
braces provided the solid control necessary to execute this type of
turn. Another significant advantage of the fixed foot braces employed
by the SmartTrack System is transfer of energy. When paddling, much
of the energy put forth by the paddle stroke is transferred into moving
the kayak forward via the foot pedals. If the foot pedals slide, as
in most other rudder systems, there is a significant loss of efficiency.
With the SmartTrack System I quickly noticed the power I gained with
the stationary foot braces.
Drag
has long been a nemesis of rudders and as long as something is trailing
in the water, there will be drag. However, the hydrodynamics of the
SmartTrack rudder were tested at the University of Washington and SealLine
claims their rudder is 25% more efficient than the standard aluminum
rudder available on the market. I was provided with two of SealLines'
rudders, one high performance rudder made of composite materials and
one standard rudder made of a high density plastic. I installed the
high performance for most of the testing and only switched to the standard
to determine any difference between the two. With the kayak empty and
the rudder trimmed to neutral, both rudders were very quiet and drag
was unperceivable with either rudder. Once I began to execute turns,
I could definitely feel the drag and hear the rudder in the water, however
I was not able to sense whether it was less than any other rudder nor
was I able to perceive any difference in performance between the standard
and the high performance rudders.
As most sea kayaks are intended for some level of touring duty, I put 50 pounds of weight in the stern of the kayak to simulate a fully loaded kayak. The turning performance of the system was predictably degraded though the kayak was still maneuverable and I could easily track in a slight cross wind. One side effect of the additional weight, on this kayak, was that the Rudder Housing drags in the water, making a gurgling noise and increasing overall drag.
Equipment
malfunction or failure can plague any sporting activity and kayaking is
no exception. Fortunately, kayaks do not have any moving parts other than
a rudder or skeg, if so equipped. The primary challenges of a reliable
rudder system are its resistance to jamming from sand or gravel and how
easily field repairs can be made in the event of failure.
I tested the SmartTracks resistance to sand in gravel in two areas, one
was the Rudder Housing and rudder itself and the other was the Toe Pilot
Control and associated side rails.
When touring in kayaks, the kayaks are often turned over on the beach
in the evenings to keep out moisture and various critters. When the
kayaks are turned, the rudders are often driven into the beach gravel,
especially if turned solo from the bow. Another way sand or gravel can
become lodged in the rudder assembly is during landing in rougher conditions
where the waves or surf are churning up the sea bottom. To test these
scenarios I scooped up a couple of handfuls of sand and gravel and poured
them over the Rudder Housing. I then lightly rinsed the material off
and paddled out letting the waves do the rest of the cleaning. When
I released the rudder it fully deployed, this time with a grinding noise
and without the resounding "thunk". I retracted the rudder
and attempted to deploy it again. It stuck a bit, but did drop into
position after working the control line a bit. On the final attempt
to retract the rudder it would not retract. I paddled to the beach to
investigate and found a few lentil sized pieces of gravel were lodged
between the rudder and the housing. I quickly dislodged the gravel and
the system was again in operation.
While
it can be the more extreme situation, surf landings or even landings with
significant wind waves can result in a cockpit full of water sand and
gravel. To test this scenario, I tossed a double handful of sand and gravel
into the cockpit, sloshed it around a bit and then rinsed it out by sloshing
sea water around then pouring it out by overturning the kayak. I then
paddled off shore to see how the Toe Pilots operated after experiencing
a bit of grit. Though I could feel the grit in the system and they did
not feel as smooth, they did rock forward allowing the rudder to turn
with ease. The other moveable portion of the system is that which allows
the Toe Pilot Controls to adjust fore and aft for different leg lengths.
Reaching into the cockpit and grasping the adjustment bars, I was initially
able to slide the Toe Pilot Control assemblies fore and aft a short distance,
but not the full range of motion. After sliding the braces forward to
the position that fit me, I paddled around a bit and then back to shore
and rinsed the kayak out again. While on shore, I attempted to slide the
assemblies back and forth and they would not move. After more rinsing
with sea water and multiple attempts to dislodge the assemblies, I headed
home to investigate the problem. Cleaning the sand and gravel out of the
system required full removal of the assemblies from the boat which required
one end wrench and a phillips screwdriver. After using a garden hose to
clean out the tracks, one assembly still would not operate. Upon further
investigation a small piece of grit, which prevented the rudder cable
from sliding through the Toe Pilot, was found and removed at which time
the assembly operated fine.
A fixed foot brace rudder system, available to the paddling masses, is long over due and the SmartTrack System is a quantum leap in the right direction. The System performed very well in my first two areas of concern, but did not fare as well in the third. It installed easily, was simple operate and adjust while underway. More importantly, it did a fine job of providing tracking control and turning while supplying rock solid foot braces for more secure boat handling. I felt the reliability challenges I met with the SmartTrack System were due in part to its precision engineering. When a couple of pebbles or a speck of grit can bring a well engineered system to a standstill, a more rudimentary solution may be more desirable.
SmartTrack Cool Rudder Wedgie and Control Cable Up-Date
The tiny wedge parts of the Cool Rudder Wedgies (CRW) used with the SmartTrack rudder system have been updated. The SmartTrack control cables have been updated as well.
SmartTrack changed the control cables from a nylon coated stainless steel cable, to uncoated stainless cable. The nylon coating was a problem because the nylon would rot off and gum up the system. The older sand-cast Wedgies work fine on the original Cascade Design's nylon coated cable. The old Wedgie has been a sporadic problem on the new uncoated cables; sometimes they work, sometimes they do not. SmartTrack redesigned the Wedgie to fit the new cables; it is slightly different now and is injection molded stainless steel.
In the image you can easily see the difference between the old (on the right) and the new (on the left) Wedgies. The most easily identifiable difference is the length of the slot down the center, Old: 1/2 in. slot, New: 5/16 in. slot.
The older CRW work well on the original SmartTrack systems by Cascade Designs equipped with nylon coated control cables. The new version CRWs will also work on the older coated control cables. For best results use the new version CRWs with the modern uncoated control cables.
There is a quantity of SmartTrack products that contain the older versions of the SmartTrack parts still on the market. You may find older SmartTrack kits, CRW, Control Cables, Blade Housings and Spare Parts Kits with the original Wedgies, and/or nylon-coated cables.
Smart Track kits with CRWs, sold through Tom’s TopKayaker Shop, will include extra new version Wedgies, and instructions, in every kit that contains old version Wedgies. This will allow the user to determine witch wedge style will work best for their equipment. At some point the supply of old version Wedgies and nylon-coated cable will run out. Compatibility will no longer be an issue. At that time duplication of CRWs in kits will be unnecessary.
The updated equipment will be the norm, the older version phased out completely.
