Kayak: The Aleut Paddle (reference to a skinboat blog post by Wolfgang Brinck) IQYAX

None of what follows is meant to provoke an argument with anybody. 

When I learn how to do anything (I'm old and I can do many different skills)--I make every possible mistake, usually come up with new ones.
• When I was little my mother told me I used to jump up and run out of the room, and miss the hallway and run right into the wall.
• I just told a friend who backpacks that I only just found out that most of the weight is carried on the belt. I used to remove the belt. On none of the backpacks I have would the belts (re-installed) fit properly on my waist. Totally clueless about one of the basics. We both laughed (at me) for five minutes.
I wonder now if making every possible mistake actually facilitated learning all my skills (I'm currently working as a teacher, I'm still a professional photographer--specializing in photographing works of art (very technical, very low pay), I've been a carpenter, electrician, plumber, activist, consultant. I've done a lot of things. OK resume over.)

THE ALEUT QUESTIONS
Just how did they paddle at 10 knots? I'm passed the discussion that maybe they were fast, but not that fast.... George Dyson made a strong case in 1991, so I'm proceeding on the premise that the Aleuts did indeed paddle their iqyaxs over significant distances at 10 knots. Over 2000 meters (1.25 miles 1.1 nautical miles (Nmiles) is slightly slower than Olympic speeds which I think top out at 12 knots. but these guys apparently could do this for several miles.

The Aleut Question is how did they do this? broken down into 'questions' would be How exactly did their gear work? What was their technique? and Is the extent gear (iqyaxs, paddles etc) really representative of the 10 knot gear?
Until someone paddles a baidarka 10 knots for a significant distance, and can do this repeatably, we really don't understand.

 My goal is to figure out how the Aleuts made 10 knots. I think I've got some very solid ideas. My plan is to give myself a year to build at least one baidarka (properly called Iqyax--or so I'm advocating). I've given myself a year (which in boat building is actually an infinite amount of time...)  By the end of 2014 I will have either
•Proved my ideas, developed them into something at least interesting;
• Disproved my ideas and shared what I've learned here, or
• Failing to do as much as I hope--share the whole list, my hypothesis, conjectures, designs, here on this blog.

I've been reading about Aleut paddles, and Greenland Paddles 
So my first step:
I just made an 'Aleut' paddle, 96" long, completely flat face, ridge at the opposite side. It was almost impossible to use, fluttering too much. Used backwards--no problem.
(No loss I can make these paddles in a few hours and enjoy it).
I'll round the power face edge and laminate a slight double-concave center ridge (exactly what you think this means) on the face.
A flat paddle face is a mess, but my Euro paddles are concave--which should be worse. They do have  a slight center ridge. So I'm thinking that balancing a paddle face is a subtle but not very difficult art. What I could do is use clay to make a center ridge--so I could easily move it around. I could then make an asymmetrical paddle face (to exacerbate the problems) and move the ridge around to balance it.

There are two basic issues with the topic of discussing paddles.
1. Descriptions. language is limited. I think I know what's going on, but I've been reading this stuff for years. A good diagram with terms would be helpful.Break down the problem, quantify it. (Above is an example of this exact problem. I should have a picture and drawing of my paddle.)
2. I don't think we've even begun to understand what the Aleuts achieved. Always in kayak discussions, skinboats less so than the others, there are too many 'experts', too much conventional (limited) thinking, too much noise and not enough knowledge and experience.
I think it would be safe to say (admit) that we really haven't even begun to understand what the Aleuts accomplished as long as people are making baidarkas and paddling them slower than 'plastic' boats (epoxy, like my strip-builts, or the mold made epoxy/glass 'yaks).

We can't know about the tools (paddles, iqyax, etc) until we can use them. Until yesterday I hadn't been in the ocean in 4 months-I wasn't as strong or as skillful as I am when I've been paddling regularly. I think any discovery of what the Aleuts really did will require a lot of deliberate practice (E.Anders Ericsson) and a high skill level.
Take the issue of 'which is the power face?'  It's easier to paddle with the ridged side as the paddle face. Wolfgang Brinck has clear photographic evidence that the Aleuts paddled ridge forward.
So what's easier to us the first time or 100th time we try a paddle has limited value compared to Aleuts who were doing 10 knots actually did.

I tried to help someone make a GP paddle. He'd never done any woodworking--so he was struggling.  I use a wood plane like most of us use a pencil.
The Aleuts compared to most of us (but not all perhaps) is probably just like this; probably more so.
I've got some ideas that I've given a lot of thought to, and I have some pretty good basic paddling skills; but what I've often noticed is how much of the discussions I've seen seem confused at best. Take as an example the common comment about GP paddles being better for the shoulders. Shoulders shouldn't really be an issue with a good stroke technique. (Jen Keck of Aqua Adventures taught me to practice 'Frankenstein paddling' --arms straight out--it forces you to rotate your torso. (Granted there are a lot of shoulder problems that aren't solved by stroke technique, and too when I'm in shape and paddling a lot, I use my shoulders at the end of my rotation.)
I've seen instructors, people who are actually paid salaries to teach kayaking, paddling shoulders only. What about the This is the Sea DVD's are most of the 'stars' really mostly using their shoulders? Maybe I'm just misunderstanding what I see. In This is the Sea number 5, a paddler hurt his wrist and yet was still trying to use a feathered paddle. (You could duct tape a paddle to your wrist, or put a hook on a plaster cast and still paddle--but you couldn't paddle feathered.)
This shoulder and feathered paddle stuff strikes me as a litmus test for blindly accepting conventional wisdom. (But here too, maybe I'm missing something. My friend who had trouble with the block plane, told me there are feathered Greenland paddles in the archeological collection.)

OK, I'm drifting into a rant here. I'm not too worried--as I don't think anybody is reading any of this stuff. If I pick up a few readers I'll edit more and watch what I say. (I'd rather paddle at 10 knots than argue about feathered paddles. Uh, I'd rather paddle at 4 knots than argue about anything.)
I'll try to add some photos of my 'funny' Aleut paddle before I tweak it.
I should also try to find or make a definitive drawing of paddle parts so we have a clear set of terms.

Toggle Kayak Handle Design

Let's see if I can add a couple of images.
I've designed a kayak handle that I'll make when I get some time.

Most kayak handles are one of two configurations. 1. A luggage handle loop that has two ends attached to the deck -- these are dangerous, especially in the surf.
Kayaks a long and currents or waves can swing the far end around wrenching your wrist.  2. A 'T' or short piece of PVC on a rope. These won't twist your hand, but they're usually flopped over dragging in the water, or  tucked under a deck line making them inaccessible.

The one I've designed is like the best ones available, Gnarlydog has a good blog on this subject: http://gnarlydognews.blogspot.com/search/label/grab%20handles
and lists the best ones available.

About my design:
• It sticks up making it easy to grab, it's always in same place, and because it sticks up it can be grabbed by a boat hook or lasso'd by a tossed line. Handle at bow is sideways, Aft is in-line - so it doesn't interfere with my Featherlite rudder. It'll also have to stand taller (and might incorporate a rest for the rudder blade)
• It's flexible enough to not wrench your hand. (I plan to use hydraulic hose or something similar for the 'post' so there are still some mechanical issues to sort out. )
It also has other benefits. It's open on your dominant side making it easier to slip your hand in. (on the other side it's closed,  it's still no more difficult than the T-handles. Aft: opening abaft (I didn't read all those Patrick O'Brian novels without learning a thing or two.)

Nothing attached to the deck of a kayak should be rigidly attached. I made a prominent rudder rest that someone grabbed onto and ripped a large hole out of the deck. He felt bad, but actually did me a big favor. Bad design. My kayak is a strip built wood core--so it has one of the strongest decks on any kayak-yet a little leverage... (As I was already halfway to drowning, it wasn't a problem, but on another day...... Yikes)

Feel free to comment on the design, ask questions, make a set of your own. Same rules as Linux. 
Just don't commercially crank them out and sell them. I know a lot of sea lions and orcas...if you know what I mean.... f
Let's see how the photos feature works.... (I"m hoping clicking on them will make them full size to read the notes.... if not I'll reload them into another Post)

See you on the water.

OK New post.
APPLE HEADACHES
I had tried to create a blog called Rotten Apples on GoDaddy, but could never figure out how to make it work. I called tech support, nice fellow sold me another $200 worth of stuff that still didn't work. Called him back. Left a message. No response.

Apple makes terrific stuff, but they have a few problems. Being better than Microsoft is no longer enough, Apple now has to be better than Apple. New Widgets are terrific, but they need to fix the old chronic headaches.
1. iTunes--Once you have a few thousand tracks, iTunes becomes a mess. I had all these ratings, lyrics, notes, custom lists, etc, etc... all the wonderful possibilities, then iTunes melted down a couple of years ago. AppleCare told me to reset or reinstall and I lost all that customization. So customizing iTunes is temporary.
2. Managing tracks. Through the mysterious workings of having multiple Macs, ipods and ipad, etc... I wound up with two iTunes accounts. I wasn't aware of this, until I discovered multiple tracks, the first ones I purchased from the iTunes Store--all those lifelong favorite tunes, began cutting out halfway through the song.
Dan Ariely did a study demonstrating that how an experience ends is more important than how it started, or how long it lasted. If it ends badly---it's bad no matter how good it was just before the end. He even cited the case of a Mozart symphony (I think) on vinyl that played almost all the way through, beautiful, uplifting, brilliant--but a scratch neat the end of the last movement caused the whole experience to be ruined.
Somehow Apple has engineered this into iTunes. AppleCare suggested deleting the tracks, then going back in Time Machine and reload the song from an uncorrupted original.
There's no way to find and pull out all the bad tracks. They lie in wait ready to smack you down. There's nothing  that sticks out. Then, how long ago were the good tracks? no way of knowing. Are these tracks all associated with the oldest iTunes account? I think so, but I'm not sure.
3. Syncing with my iPod and iPad. This has become almost random. The iPad never synced photos very well. Just the other day I wanted to show students some images I'd made. I dragged 3 jpegs into one of the files that is on my iPad. Then I sync'd, re-sync'd and re-sync'd.... it took about 4-5 attempts before it worked, instead of a few minutes, class was long ended when it finally worked.
I have a lot of Audible Books, periodically iTunes simply refuses to load them, then once they are loaded, it refuses to sync them to my iPod. It did this the other morning. So I did a reset iPod......an hour later I had to drive to work without an audio book. The first 20 minutes were lost because of the Screwed you! dialogue window that popped up long enough after I'd selected Reset.
DOES ANYONE IN THESE COMPANIES EVER SEE HOW REAL PEOPLE USE THESE PRODUCTS AND SOFTWARE???
4. Now my iPod won't scroll up and down. It could be caused by the cracked glass touch screen, but it scrolled just fine until I did the Reset, so I'm left wondering, and paranoid. (Are these problems engineered by Apple because they want everyone to immediately jump to IOS7? My son asked me if I was using iTunes 11. I said, I think so. He laughed.

Have you seen the South Park episode where Cartman is turned into a human centipede because he blythly selected 'accept terms' on an iTunes upgrade. Everyone, including his mom, is incredulous that he would agree to anything he hadn't read.  Are my hassles somehow connected to the cryptic box that appeared the other day announcing 'iTunes conditions (or something) have changed.'
How can these Agreements be legally binding? Does anyone ever read them? Is it possible to read, understand and alter them? I can't see these things being held up in a court. You have a product, the company tells you it needs to be upgraded, we trust them, then after they start the process (by downloading the file) up pops an agreement and nothing more will happen until you agree to it. It's not a business agreement, it's a shakedown.

So here's what I think (otherwise this is just a beef from someone who doesn't amount to a blip on the concerns of the manager of the Apple Care phone center guy in Bangalore....)
The day will come when people do most of their writing, designing, image and video editing on machines that are not connected to the internet, that use out of date software. Smartphones and pads will be how people will connect. Files from our Isolated Computers will be transferred to phones and then over the internet.
The dates on these Isolated Computers (Quarantined? I have an opportunity for a terrific neologism here.... don't blow it) will be 2009 or 2007, and just keep being set back every year.

I have the sneaking suspicion that most commercial software have time bombs written in, I suspect that many of these may be introduced with the last upgrades before a new version is offered for sale. How many times has an application started to act wonky and you think, 'Oh, well, I may as well pay a few bucks and upgrade....' Once computer code is compiled there is no way to find this stuff. I'm willing to bet that if I'm right that these bombs have cost us more money, and caused more hassle than all the spammers and virus makers combined.

There are two ways to uncover if this is happening. First, a whistle blower.  But hey, Silicon Valley is no NSA. Not likely. Second, scientific method. Techs with large numbers of computers can upgrade some but not all prior to a new version and then document what happens.  An alternative method would be if users all over the globe began sending bug reports to non-industry connected sites that can compile, sort and analyze the data.
Has anyone else suddenly experienced a scrolling problem on their 5 year old iPod after they updated to iTunes 11, but not yet to IOS7?  A lot of these might just be bugs, code is 10% writing 90% debugging, which means I'm probably just paranoid, but ah-ha! it makes it easy to dismiss Time Bombs as just another bug.

With the Adobe monthly rental fee, I asked myself, do I need to upgrade? I use Illustrator a lot, Photoshop some, Lightroom a lot, but not as much as Illustrator. Lightroom seems to continue to make improvements, but Illustrator and Photoshop (CS5) can do everything I can think of, no version in the past few years has really made that much of a difference--so I can see using these until I die or go blind. At some point however, all the system upgrades, HTML upgrades, etc will jam them up. (When I lost Rosetta I lost a lot of software I occasionally used, and had to upgrade a few others, like Nisus Writer. Microsoft Office that I had stopped working. The newer version of Office on my school computer was no different, and had the same dumb multi-step garbage MS is famous for, so there was no way I was going to pay for more of the same. Instead I found OpenOffice.)
So at some point, in the near future, I will need a 2012 computer running an old date, with the Network disconnected.

Oh last thing (I'm rambling, but no one's reading any of this so, ah so what, eh?)
The reason my iPod glass touch screen is cracked is there is no practical way to carry the thing. It either goes in a pants pocket, with keys, or when I lift a kayak instead of my leg I now have 75 pounds pressing in the middle of the glass. In a back pocket, you sit down on it. In a shirt pocket, it slides right out, or bounces out if you leap (I guess I leap more than most people.)
Every time it bounces off the floor I think two thoughts, 'That's amazing tough, and Steve Jobs must think that the way we are supposed to use his dingus is holding it in one hand while we sit on the floor in our living room (where there is no couch, but maybe ten bowls of strawberries and untreated pancreatic cancer) and do nothing else. I'm sure if he was asked, 'What are you supposed to do with it when you're doing something else?' he would've responded, 'You're not supposed to do something else.' with a few expletives.
A protective case? I've bought more than a few of these. They are bulky, an inch thick and seem designed for rugby players. The Apple Store always amazes me, 50 choices of iPod and iPhone holders, an amazing range of colors and patterns, and not one belt loop, not even a neck lanyard.
So far the best carrying option I have found and use is a DryCase (no case just a tough vinyl bag) and wider lanyard, but the lanyard not hanging on my neck, but hooked on to some gear on the back of my life jacket(PFD). The DryCase doesn't hang, it's tucked into the front of my life jacket. When it just hangs around my neck, it swings around and it's not very comfortable on my neck. 
The new iPods have the tiniest little wire connector. Sorry. That's not much of an improvement.
When the iTime, iWatch, comes out, I wouldn't be at all surprised if it was a wrist watch without a watch band, or if it does have a band, it won't have a clasp.

I went on line to make the tentative steps of buying another iPod. Asked about engraving, I copied and pasted some Chinese characters. I know the thing will be engraved in Shenzhen, and I'm pretty sure I read somewhere that in China Chinese purchasers can get Chinese characters, but apparently not yet here.

I'll try another iPod restore. And I'll write my next journal entry into a composition book. Funny how I still have 20 year old journals, but all the things I've written on a computer in the 90s are long gone.

Always Will N 2

Is this how to add a new entry??


Welcome to WillN2
I've been WillN2 start a blog for quick sometime now. Made the mistake of getting sucked into the GoDaddy vortex.  The money goes in and nothing comes out.
Their easy help packages I found to be a complete joke.

Disqus worked once for me, and then it never worked again. All this hassle with the passwords. Anyone under thirty won't remember when the way to keep your passwords safe was 1. never use the same one twice, 2. never write them down and 3. never use anything that's a common word, a number, birthdate, your dog's name. The same people who had these solutions quickly began asking for your first school, first pet, your first grade teacher's name as security questions.

This is why I don't buy anything from iTunes, haven't purchased a new App in over a year, and it's also the reason Apple Tech Support gave complete access to some hacker who who knew one of the other e-mail addresses of a Wired reporter a couple of years ago.
I also don't read the New Yorker, Wired, National Geographic and probably one or two other magazines on my iPad--I can't. The security procedures are a disaster. I've seen about three issues of Wired about as many of the New Yorker. I loved the single app-issue of National Geographic. I paid for a year, I never got passed some ad afterwards. I gave up and forgot about it until I noticed they'd renewed the subscription and charged my credit for the next year.
I think Conde Nast means NO ACCESS in Gran Marnierian.

I find a lot of tech peace of mind in the mantra, "someday, this stuff is going to work."

Anyone else have these hassles? I complain a lot. I like things that can actually work. When I first learned Photoshop 2.5, it made me crazy. I could do things with it, made a lot of money on my first photo I did with it. (Can I post photos here? Have to figure that out.)  That first image was 60 megabytes, took me almost a month. Waiting for the thermometers to fill up took more than a half hour in many cases. I read four books waiting for those things.
The crashes and headaches drove me back into the darkroom. I didn't give up on Photoshop, but it was incredibly satisfying to be able to understand everything that was happening making an image. I built machines to process film, rock my trays, a special little light to bring up the highlight detail, figured out sepia toning--it's not just orange Instagram users.
I got tired of looking at the surface of photos, the four colors printing in magazines, the limitations of color negative, positive--even Kodachrome. The palettes and textures are limited after you've looked at a million or so images.
That's where the sepia toning came in. Bluring the image just slightly, partially is a better word, allowed the image to separate from the surface of the paper. I found out later Gerhardt Richter, a great German artist using oil paint, had done the same thing.
Now, except for a few people, and a lot of college kids, chemical photography is effectively extinct. That's okay, no regrets. I'm happy I was able to do what I did, and I really like digital. With digital there aren't all those amazing images that didn't turn out because of exposure, focus, and development problems
