Why is Russia Bombing Blogger Sites?

Historically, Russia represented about 0.2% of my page views. Reasonable enough. More that 95% of the trafic came from the US and UK (England, New Zealand, Australia, and Canada), with a smattering from Europe. Makes sense. These are the people that sail and who speak English.

Starting during the last election, and continuing today, though slightly less dramatic, 10-60% of the traffic comes from Russia. None of this represents sailors or actual viewers. Probing eyes? I can't imagine why. Intentional swamping of data lines? Probably. Sponsored by the Russian government? That seems certain, give the scope and level of control. I must assume this ratio of junk traffic is uniform across the net.

And Putin wonders why relations remain frosty? Does Trump yet fully accept, in his heart, that these people don't use the same rule book we do? Perhaps he is coming to that conclusion, though why it was not school-boy obvious last year I can't guess.

Attainable Adventure Cruising

It's not smart to advertise links to sites that could siphon readers and dollars away, but sometimes you run across a page that simply must be shared. Though I have never met John, I have exchange considerable correspondence and consider him a friend, for the good character and free exchange of ideas he has shared. His site (https://www.morganscloud.com), complete with on-line e-books, is a treasure.

Do I agree with him on everything. Heck no. I don't agree with myself all of the time. I have more of a coastal and multihull perspective, and he has an off-shore perspective. But John displays rare combination of open mindedness and traditional, conservative seamanship that is extremely refreshing. I respect his opinions, always.

Coal is Not Coming Back

This is NOT me getting political. This is simply a list of observations on how Appalachia has been bamboozled.

  1. Pipelines = Cheaper Gas. More pipelines mean reduced oil and gas prices, meaning less reason to burn coal. Although coal remains cheaper than gas, there are more costs associated with burning coal (unloading, stockpiling, grinding to dust, emissions controls, boiler fouling, increased wear, coal ash disposal). And since most people like cheaper fuel and gasoline, most people at least tacitly like things that make gas cheaper. This will lead to continued at least quiet bipartisan support of fracing.
  2. Time Line--Utility Plant Move Slowly. Even if coal were significantly cheaper than gas--which more pipelines and drilling prevent--power plants are decades in the planning and construction. If you were budgeting for a power plant, would you propose coal, knowing that the neighbors will oppose permitting and that the regulatory pendulum will swing back in 4 years, but no more than 8? No matter my political temperament, I would not see this as a long term strategy. I would not stake my job on a coal-burning plant that would be shut down a few years after it opened. Therefore, planning of new coal plants is very unlikely. At most a few might go through a few motions, but they won't commit the money.
  3. Clean Coal. I'm an engineer and like the science. But I wouldn't invest in something that is economically marginal and still politically vulnerable.
  4. Most States Determine Their Own Rules.  I know several coal plants that were closed, all the result of local pressure. States can set their own rules. A change at the federal level will have no influence on most closures. Finally, no matter how conservative the voter, no coal plant will receive support at the local level (NIMBY).
  5. Health Care. Unemployed miners should be able to figure out where that is headed.
They allowed themselves to be distracted by glitter and words they wanted to hear, but that just couldn't be true.Times change, they always have, and it's a little cruel.

I'm not even sayin' whether this is good or bad, it's just what the facts reflect. You don't put the genie back in the bottle. Historically, can't ignore the bloody shirt, and there is a case against coal that goes far beyond global warming.

Happiness

Life consists of many part and moods; when my thoughts drift to what is important, I think of Lin Yutang and The Importance of Living. It belongs in the library of any philosopher, and no sailor, climber, or person wanting to milk the full value from life can not be a philosopher. From a chapter on happiness, adapted to my experience (inspiration from Chin Shengt'an):

_______________

My Seven Happy Moments. There have been more, and will be to come, but these few thoughts step forward today:


  1. A Cigarette boat comes joins the 6-knot parade out of the the harbor through a narrow channel. But he can't wait in line, guns the throttle, passes to starboard, and runs definitively aground in 12 inches of water. When you return to the harbor after a brief sail, the young men are still aboard, arms akimbo, visually proclaiming "we're cool." Is this not happiness?
  2. You are anchored in a pastoral cove, alone with your thoughts. There is only the faintest breath of air from the east, just enough to swing the boat, but not enough to ripple the water. It is not hot, just warm. Without a cloud in the sky, the sun is a low, an impossibly large red orb that cannot last. Is this not happiness?
  3. In preparation for a climbing trip to the Wind Rivers and Tetons that will involve long pitches on snow and ice, you climb pitch after pitch of easy rock rock at a convenient crag near home, unroped, to build speed and confidence. Nearing the top of a straightforward 5.5 crack, you overhear several 20-somethings chat about how difficult the climb was (with a rope), lament that there fathers could not join them, but allow with great understanding that "Dad is in his 40s" and it's unrealistic to expect so much. I easily top-out sans rope, and while walking past them mumble that I'm 48 (some years ago) and that my 12-year old daughter also enjoyed the route. Is this not happiness?
  4. I sit in the backyard with a good book (Lin Yutang), with DEET-based bug repellent on one leg and catnip-based repellent on the other, the stuff of another article research project. The DEET leg is all alone, and the mosquitoes only circle the other, confused and unable to process critical landing information regarding the tasty mammalian flesh below. Is this not happiness?
  5. Since my daughter was old enough to baby sit, she would fill bags with teacher-like stuff and spend hours developing an activity plan and preparing for her "job." During her senior year of high school, after several false starts, she announced that she knew what she would do in college. She is going to be a teacher (this was some years ago--she is student teaching now). Is this not happiness?
  6. Your career of 32 years comes is victim to massive consolidation following a merger with a company that does not understand what you do. At the same moment, you realize that for the first time in your life you have a chance to chose your path. A cross roads to be faced as an adult, with all of life's experience to draw upon. Is this not happiness.
  7. My daughter is home on break from college. We are sailing in light winds and she is collapsed, semi conscious on the bow. Is this not happiness?
 The kids, armored against jelly fish.
_______________

 Sometimes I write solely to practice putting words on paper in a thoughtful way. Unfortunately, I don't have a philosophy sufficiently considered to express at length. Whenever I examine it closely, it flits away, unwilling to pinned down or well understood. Faulkner said that "free time only exists when not measured" (The Sound and the Fury), and so perhaps philosophy can only be fresh and thus worthwhile so long as it is unexamined, not ruined by anything more than a furtive glance in its general direction. Maybe it's simpler than all that. We should just be happy.

European Paddle vs. Greenland Paddle

For an old guy, Greenland paddles win.

A Euro paddle blade is leaf-shaped, nearly half as long is it is long. Or rather that is what we have come to accept as normal and 21st century. It is superior for whitewater kayaking and racing, where it provides a positive, even harsh grab on the water.

But over the years I've run into folks using Greenland paddles with their sea kayaks.  Though the urban legend is that they were long and slim because that is the only thing they could make from drift wood, when you consider the craftsmanship that goes into a skin-over-frame kayak, that sounds like lame reasoning; these people could craft anything from a few bits of wood and sinew, and in fact, they used broad paddles in other craft. They developed what we now call the Greenland paddle because it has some unique advantages.

These are works of art. Mine was fashioned from a 6' x 3/4" x 3 1/2" (a common 1 x 4) board and a center of aluminum tube in a few hours, and probably performs better.

The length is about the same--a little less than 8 feet. The blade in only 1/2 the width of a Euro paddle, but the length of the blade is over double, resulting in greater projected area. Because it is not scooped like the Euro paddle, the catch is much softer, and it does not generate as much instantaneous power. However, because it has a higher aspect ratio, it actually creates greater lift once the stroke is underway.
  1. Lighter. My Greenland paddle is 25% lighter than my fiberglass Euro paddle.
  2. More buoyant for rolling. 
  3. More lift when used in a sweep stroke for rolling or bracing, because of the higher aspect ratio.
  4. More resistance and better grip on the water at mid-stroke.
  5. Smoother catch and release.
  6. Easier on the wrists, shoulders, and elbows.
  7. Quieter.
It was "1" and "6" that caught me attention. Although it does not provide the same acceleration, it is faster through the water over the long haul, easier on the body, and significantly lighter. I'm still not used to the look, but it is more efficient over a long day.

Downsides? A few, but they are minor.
  1. Harder to buy. But you can make them rather easily. They don't need to be laminated and beautiful.
  2. Not as much blade in the water in shallows. But you can use a shallow, more horizontal stoke.
  3. Most designs do not feather, but that can be fixed by incorporating an adjustable ferrule. 
  4. Typically the shaft is fatter (1 1/2-inch vs. 1 1/4-inch standard or 1 1/8-inch small). Hand size and whether you wear thick gloves (a smaller paddle works better with thick gloves) may dictate which is better, but I find the fatter shaft is harder on my wrist and hands. Personal preference enters in. 
  5. Learning a new stroke. Where a Euro paddle is simply pulled, the smoothest and most powerful stoke on a Greenland  paddle is delivered by a gliding pull with the blade moving at an angle, as when swimming the crawl efficiently. The blade is high aspect and generates a lot of lift when moving sideways. the stoke is also lower angle.

Feather. Most sea kayakers adopt a feathered paddle after some experience. By angling the blades about 60 degrees relative to each other, even when the arms cross between stokes, the wrists remain in a neutral plain, never flexing. The key is to pick a control hand that grips the paddle, and to let the shaft rotate in the other hand during the cross over. The non-control hand need never grip the shaft tightly. Gloves help.

Whitewater paddlers often use an non-feathered paddle--it can be problematic to keep track of the twist angle when paddling rapidly or throwing out a quick brace stroke. I use zero feather in technical whitewater.

Greenland paddles are typically not feathered, because a more shallow stroke is used, minimizing wrist flex, and by tradition. Many paddlers find an non-feathered paddle easier to roll, because similar to the whitewater case, they don't have to remember the feather angle. However, I have wrist problems and really like feather, although less than the traditional 60 degrees used with Euro paddles. My Greenland paddle is feathered only 30 degrees.

It's  little ugly, but by using aluminum tubing in the center I dropped the weight to about 65% of a common paddle and gave it 30 degree feather.  I am wondering if less or even no feather might be best for Greenland paddles. It may be a matter of learning a new stroke.


Where can you get a Greenland paddle? First, make you own. There are many on-line sites with instructions, and if you are handy in the wood shop, a basic paddle won't take much over an hour or cost more than $5 to make. You can buy them, of course, but artwork and craftsmanship cost money.

If you want adjustable feather or a Greenland paddle that can be broken down for storage, Duckworks sells carbon fiber ferrules for ~ $25. This also makes it possible to create feather. Duckworks offers two ferrule options:
  • Standard. Allows for O degree, 60 degree right, and 60 degree left feather. The shaft is 30.6mm (1 1/4-inch), which is generally considered standard for kayak paddles.
  • Greenland. There is no allowance for feather, although you can obviously mount the ferrule with some rotation to create a fixed feather angle. The shaft is 38.6mm (1 1/2-inch), the traditional fatter Greenland paddle diameter. 
Additional holes (you drill em') can create custom feather angles.


This is the elegant way to do it [details on Duckworks]. Add a slightly longer center section and 30 degrees of feather, and this is my dream paddle!
