I've been mulling over the thread that rotated around the video "a
conversation with Derek Hutchinson" and some of the comments. Derek
Hutchinson has said that he thinks design innovation in sea kayaking is
moribund, if not dead, and this got me to thinking. In many ways I agree
with him. Especially over the past few years with the popularity of the
"Brit Boats"; many of which are indistinguishable from designs of the 1970s.
I suppose you could say, "why tinker with perfection" but I'm not at all
sure that the Brit Boats are perfection. At any rate, whether you are
admirer of this style or not, they certainly don't typify much in the way of
innovation.

At the other end of the sea kayak spectrum you find the "big boats" that are
mostly refinements of boats by BC and PNW designers of the 1970s. There are
a few boats in the middle but, for the most part, looking at trailers of
boats at the Port Townsend Kayak Seminar last September I was hard pressed
to find anything radically different other than the traditional ones. There
were the rounded hulls of the "heavy haulers" and the hard chines of the
"brit boats"; the holes for skegs in one and rudders on the other.

This is in dramatically stark contrast to white water kayaking which has
undergone what can only be called (if you'll pardon the overused phrase) a
paradigm shift over the past 15 years. Rivers once populated by 12-foot-long
river runners has moved to a point where there are boats specialized for
water conditions and paddler size. And all of them are shorter than they
used to be. So you'll find creek boats, river runners and playboats with the
last two categories divided into boats further divided into categories for
paddler size. The RPM and RPM Max are good examples; featuring nearly
identical hull shapes with the only difference being the size; both length
and vollume. It's now common to see playboats offered in three (or more)
size ranges for small, medium and large paddlers.

It would be easy to dismiss this as marketing hype if it weren't for the
simple fact that the RPM and RPM Max are the two most popular kayak designs
ever produced for white water kayaking. In fact, when Dagger tried to drop
the line a while back they found that they couldn't do it. So many paddlers
demanded the RPM be returned to their product mix that Dagger capitulated
and put it back in the lineup.

So now a white water paddler can select a boat based on performance
requirements and not just settle for a boat that fits him (or her). So I
could watch a 150lb paddler do a few cool tricks in a playboat and go try
that playboat in my size with every expectation of having the boats perform
virtually identically regardless of the volume. It's just a matter of
scaling up or down. Volume changes but so does beam and length and cockpit
size yet performance for the larger paddler remains very close to the
performance for the smaller paddler.

I think sea kayakers and sea kayak manufacturers should be paying close
attention to this.

Historically there have been very few sea kayaks which were essentially
identical designs which were changed only to accommodate different sized
people. Matt and Cam Broze might have been the first to do this on a
production basis in the 1980s and 1990s with their Mariner Elan and Express
(and subsequent volume versions of the Express). They designed the Express
first, then modified it to a lower volume (lowered the deck), and then
reduced the volume even more for petite paddlers and called the result the
Elan. The result was one hull form with reasonably identical performance for
paddlers of different sizes.

There are also the Romany versions and several others. These, however, still
ask the paddler to make some compromises as the versions are fixed in size;
typically HV and LV If you fall between the cracks in sizes they you will
have to simply choose the best fit and hope for the best. And in most kayak
product lines the boat that fits you might have completely undesirable
performance characteristics. So if you love the performance of the "Brooks"
you might have to settle for the "Lopez" (or, worse yet, the "Moses Lake")
because nothing in the high performance range is made to fit you. You're
outta luck.

At least until recently.

Last September in Port Townsend I noticed that George Gronseth (
www.kayakacademy.com) had a few of his new design, the Illusion, in
different volumes. In fact George even had a cockpit mockup which was being
used to determine which version would best fit an individual paddler. They'd
seat the protential buyer in the mockup and then adjust the "volume" to the
point where the paddler felt most comfortable. Then Gronseth's manufacturer,
Sterling Kayaks in Bellingham, Washington, would churn out a nicely built
Illusion that not only fit the paddler precisely but would paddle pretty
much the same (for them) as a boat built for a bigger (or smaller) paddler.

Let me emphasize that the Illusion is not just offered in HV or LV (high
volume or low volume) like other designs. The Illusion is adjustable in
volume. If you need a deck height of 11-3/16 inches then you'll get a deck
height of 11-3/16 inches; not 12 and not 11.

This doesn't mean that Gronseth's Illusion will be the perfect sea kayak for
all paddlers; or even a single individual paddler. I remain convinced that
there is no such thing as the perfect "all around" kayak. I'll still want
one kayak for surfing and another kayak for long trips and yet another kayak
for rock gardens. I don't believe that will change (but we might be getting
close).

What it means, in my opinion, is that when Pam buys an Illlusion that is
sized specifically for her (this is pretty much inevitble, by the way) and
raves about it to me (also inevitable), I can buy one in the reasonable
expectation that the one I buy - sized specifically for me - will fit me
just as well as hers fits her.

There are still bound to be some differences, however. For one thing, the
length of the boat does not change and, since I'm a more powerful paddler
than Pam is, some of the performance characteristics will be different for
me than for her. And, of course, changing the volume of a boat - which means
flare changes too - means that stability factors will change. They'd change
anyway since I'm heavier and taller. Until George can adjust length and beam
along with volume, at least. You can take a look at the Illusion CV at
http://www.kayakacademy.com/catalog/Illusion.html .

I find this exciting and the trend towards customizing a boat for purpose
and size exciting. But the infinite adjustability of the Illusion is, for
me, truly innovative. Up until now you could only do this if you built your
own design or modified someone else's design (this can be problemmatic for
some designers) or did your own SOF (which Pam and I are going to do next
month at Cape Falcon Kayaks). In fact, this is more like the traditional
method of building a kayak.

Your comments and ideas are encouraged.

Perhaps I am more dense than usual today, but I seem to be missing the 
point. On the one hand, you speak of a lack of design variation; on 
the other you speak of custom-sized boats.

Is this not apples and oranges?

The fact that a boat is available in a multitude of sizes does not, it 
seems to me, make it a "new" or different design.

I must hasten to add that I applaud the movement to making boats in 
varying sizes. I think it's a great idea!

And I also agree -- although I cannot afford to follow up on the idea 
-- that having different boats for different purposes (or even 
different moods!) is also good.

But there seems to be a fairly limited range of variables involved in 
building a kayak, so that they will tend to resemble each other. And, 
it seems to me, there is a certain inertia in the marketplace that 
almost dictates that a kayak must look like other kayaks to gain any 
foothold in the market.

As an example, there were some reviews of a kayak in the past year or 
two (my memory isn't what I'd like it to be) which has sides that 
curved inward in the middle of the boat. This, to me, was a new 
variation in boat design, but it seems to have disappeared from view. 
I have seen nor heard nothing in many months about this design. 
Perhaps it was an ill-conceived design from the performance point of 
view and has justly been tried and sentenced. Until I read otherwise 
though, I will  hold my suspicion that people didn't buy it because it 
looked *too* different.

An interesting topic. I'm looking forward to reading other comments on it.

I thought I said "innovation" rather than variation. There has been a fair
bit of variation. Not a whole lot of innovation. The Illusion's advance is
in customization of fit and the design of a boat that makes it relatively
easy to manufacture it in custom sizes. This is not as easy as it sounds.
I'm hopeful that more customization will follow. It's much easier to do
multiple sizes in plastic boats once the tooling is made; just spit 'em out
and weld 'em together. Composite boats are more complicated and take a lot
more work.

Well, the idea of making a performance range variable across an multitude of
sizes is, at least, innovative.

You might have thought so 15 years ago when thinking about white water
kayaks. But a modern w/w playboat really doesn't resemble a 1994 river
runner very much. There was, of course, an evolution in the designs from the
old pointy-at-both-ends river boats through the Perception Pirouette to the
latest 6-foot long flat-bottomed playboat. But the product of 1975 and the
product of 2009 look far different from each other. So I'm not altogether
certain that making all kayaks look one way or another is all that important
except, perhaps, from a marketing standpoint.

I think that it was not enough of an advance in performance and too radical
an advance in "looks". But I never got to see one in real life let alone
paddle one.

The boats you are thinking of are from Warren Light Craft
http://www.warrenlightcraft.com/

The boat designer/builder spent many years as a multi-hull sailboat
designer.  He's used to going against tradition ;-)

The paint jobs on his boats are amazing.  I'm not sure if I ever want to
see the customer who goes for the "we can match the color of the kayak
to your vehicle"....

A year or two I got a tour of his manufacturing.  It's an interesting
process of vacuum bagging in an oven.

Craig,

As George Dyson wrote in "Baidarka, the Kayak":

"No matter how many of these vessels are built, and no matter how far we go with the evolution of their design, their form will bear a resemblance to the past because the laws of the ocean have not changed."

I worked as a teacher for 30 years or so.  And, every year at the fall "in 
service" we were treated to dissertations on innovative ways of 
accomplishing our task ... but about 90% of the time those new techniques 
were never evaluated for their efficacy.  To wit, there were _no_ follow-up 
studies to establish that the innovative techniques helped students develop 
skills or understanding any better than what we had been doing for years 
... techniques and methods which _had_ been tested, which were based on 
sound understanding of cognitive development in adults and younger folks, 
and how pleasure/reward motivates people.

So, when someone berates a community of developers of kayak designs for 
failing to be "innovative," my skin crawls.

In fact, a person like Craig might berate the Broze Bros. because they 
failed to "innovate" after developing and successfully marketing there 
epoch-making designs of ... when? ... the eighties?  the nineties?  When I 
visited their shop in 1993, they had essentially the same hulls on the 
racks they were selling in 2005.

There is a reason for the success of the Broze hulls:  they are based on an 
understanding of the physics and hydrodynamics of water, in particular, how 
changing the part of a hull engaged in the pressure distribution a paddler 
puts in the water makes the hull "carve," much in the same way a ski with 
side cut carves a parallel turn.  [If you ask Matt about this, he will 
freely tell you they applied ideas learned in designing skis to kayaks.]

So why would the Broze Bros. change their hulls?  To be innovative?  No. 
So they would __work__.  Engineers know that if a design meets its goals, 
and tinkering with it only degrades its performance, you should not mess 
with it!  If the goals change, _then_ the design might change.

Which leads me to the second reason sea kayak hull design innovation (the 
real kind, not the marketing kind) has plateaued:  paddlers are not doing 
radically new things with their hulls.  Most want a compromise boat that 
can carry a load, carve turns, roll layback fashion, pass through the water 
with a modicum of effort, and be easy on the pocketbook.  As we all 
realize, some of these design goals are in conflict with each other.  About 
the only thing to change in hulls the last several years is reduction in 
the height of the back deck because folks favor layback rolls nowadays.  In 
fact, many "older" designs have been modified to handle laybacks, by 
cutting the back deck down.

In contrast, the WW crowd _did_ change what it wanted to do with its hulls, 
and there _was_ true innovation in hull design:  playboats came into favor 
over trippers.  Someone who spends an hour or two exploring what he/she can 
do on one wave at river mile 17 does not want to haul around a lot of 
useless hull; planing and edging become paramount; volume and stability do 
not.  In brief, because there was a sizeable element of the WW fraternity 
which _changed_its_paddling_requirements_, hull form changed.  No similar 
change in paddling practice has occurred in sea kayaking.

Finally, a breakthrough in the basic understanding of the craft can also 
generate true innovation:  if someone develops a better understanding of 
hydrodynamics, then we may see some true design changes in sea kayaks, in 
the same way winglets appeared on airliners to increase wing efficiency. 
To date, nothing parallel has occurred in the science of pushing a hull 
through water.

Good point. The teaching of mathematics from elementary school through
university seems to have hit a serious speed bump due to "innovation" in
teaching.

Ya, but we're old guys. We really aren't likely to change our ideas.
Innovation is anathema to us because it represents change. In fact someone
backchannel mentioned that sea kayaking is chock full of old guys. Maybe
that's the reason. Heck, I'm as bad as anyone else my age as far as cranky
goes.

I don't think the Broze Brothers had to keep on innovating. Edison did it
(but there are even some questions about that) but how many strokes of
genius do we demand of a designer? And, to be fair, some of their innovation
was recognition of someone else's idea and implementation in their own
products (to wit: the Coaster). In Matt and Cam's case they had spent 20
years chopping up fiberglass hulls and rebuilding them. I think berating
them for not continuing to innovate would be pretty unfair.

The Mariner hulls worked pretty well but, again, as people get older they
find little need to change. If it works, then don't fix it. Matt and Cam had
built a pretty nice little business, had created at least one legendary
kayak, and eventually wanted to do something other than sit in a storefront
listening to other people plan kayak trips.

But, speaking as an engineer, tinkering with a design is pretty much what
engineers live to do. We don't need no goals; we just like to tinker.
Somewhere there are kayak designers who are tinkering with designs right
now. Maybe the problem is just getting those designs out and recognized. I'm
just curious as to why there were so few willing to take a Mariner design
and take it a bit further. Actually, someone has...  or at least thinks he
has. Brian at Cape Falcon Kayaks has tweaked the Coaster into a
skin-on-frame design that he thinks is an improvement on the original. I'll
be able to comment on that better in a month or so.

Well I'm not so sure about that. I drove over Deception Pass last weekend
(moving the Muthah-Ship to its Oak Harbor slip) and there were lots of
kayaks on the water. Certainly paddling Deception Pass is more radical that
what the majority of sea kayakers were doing 10 years ago; or even five
years ago. And anyway, most sea kayakers are over 40. Maybe we'll need to
see a large influx of 20-somethings enter the sport in large numbers before
we find out whether radically new things can be done with the hulls. For
years white water kayakers were told that it was the sales of sea kayaks
that supported the white water designs. That they didn't sell enough white
water boats to justify the expense of the new designs but that the sea kayak
crowd kept them going. I wonder if that's true any longer.

This was, I firmly believe, because the people who were doing white water
migrated into other sports. The last two years I was on white water it was
damned hard to find anyone over 35 on the river. And the older people were,
like me, mostly in RPMs. What changed was the demographic. No one my age was
interested in 65 foot drops, that's for sure.

This is a "chicken and the egg" argument. Does innovation stem from a change
in goals or does a new design promote a change in what people decide they
can do? It's probably a little of both. Pastic boats certainly changed white
water paddling and allowed people to do things that they wouldn't have
risked a fiberglass boat doing. But I also think that the sea kayaking
culture might be in for a new period of innovation. As I said in the
original post the Illusion offers an innovation in its ability to vary fit
over a wide variety of paddlers. The fit that white water paddlers have had
for the past five or six years is probably going to find its way into sea
kayaking.

Nice to see a spirited chat on here. It was getting way too quiet.
