Merry Christmas 2021

 Whew, it has been a real busy last 8 months or so of life. Lots of exciting but stressful work, spiced up with some unexpected challenges, anxiety about the coronavirus pandemic, environmental disasters, etc. Nevertheless I have a lot to be thankful for. Number one is my wife Rhonda, seen here where we're celebrating Christmas at her family's home in New Hampshire. 


I'm also thankful for our new dogs- little french bulldog rescues Violet and Petunia who are a lot of work but super loving. Here Petunia is in one of her favorite spots, sitting in my lab while I play computer games. Those EYES! <3 


And here's one with the whole gang together.

Foolishness vs. Fear Graph

 I'm not sure if I saw something like this before or thought it up from scratch, but I made the figure myself.

Fanatic Skysup WS edition foiling video and review

On Friday I had a good windsurfing session on my newish hydrofoil windsurfing board, the Fanatic Sky Sup Foil WS. I filmed it with a GoPro camera mounted to the end of the boom. I was using a 4.7 sail, and the foil was a Slingshot Infinity 76 in the "B" configuration, set as far back in the finboxes as possible. The wind was around 15 knots from the SW.

I'm really liking this board now, although it was a major adjustment from the first board that I started foiling on; an older Exocet formula board. The Sky Sup is meant for maneuver-oriented sailing (as opposed to speed-oriented sailing), and is also meant to be useable without the sail for SUP foiling or with an inflatable wing for "wingfoiling." It's very short; 210 cm, and the mast track is placed very close to the front footstraps. The footstraps are near the centerline of the board rather than out near the edge like on a formula board. These aspects of the shape and the placement of the fittings required me to radically change my stance, sail position, and body weight distribution from what I'd gotten used to. The sail must be held with the mast straight up, or or even raked towards the nose a bit, rather than raked back towards the tail as it would be when sailing fast on a board with normal geometry. Controlling the altitude of flight is done more with direct foot pressure and less by applying weight to the mast base. Because of the sail rake angle you need to set the boom lower and/or use longer than normal harness lines if you want to hook in. You can actually sail it without a harness, though, since the forces in the sail are so much less than on a non-foiling windsurfer.

I've used the board with sails from 4.2 to 6.8 meters squared. It handles the 6.8 adequately, but the sweet spot is with smaller sails. Compared to the formula board, the Sky Sup is more particular about having the right sized sail for the wind. On the formula board you have some more leverage to keep the sail sheeted in and the elevation controlled when the sail is overpowered, whereas on the sky sup you just have to sheet way out. When underpowered on the formula board you can still get it foiling with some "stir" pumping of the sail that applies lateral pressure to the vertical part of the foil and translates into forward speed that allows liftoff. But that doesn't work as well on the sky sup, where pumping becomes more about "porpoising" the horizontal parts of the foil. As I learn to pump the sky sup better the liftoff threshold may end up being about the same as on the formula board, but for really gusty conditions I think the formula board may still be a more forgiving foil platform.

The most annoying thing about this new board versus my formula board is that they don't use the same "finbox" system for attaching the foil to the board. The sky sup uses a "pedestal" mount with four bolts that go into two parallel mast tracks and allow fore-aft adjustment of the foil position. The formula board uses a traditional, fixed-position "deep tuttle box" mount with two bolts that go down through the deck of the board. Further complicating things, the foil itself has different configurations placing the vertical attachment more forward or back on the fuselage, and I need it in "C" position for the formula board but "B" position for the sky sup. The whole change-over takes half an hour or so of sitting in the driveway unbolting and rebolting things, re-greasing the bolts, etc., so I kind of have to commit to whether I'm going to be using just the sky sup for a while or just the formula board for a while. I think what I'll do is use the sky sup in our "windy season," with 6.8 sail being the max and waiting for 10+ knots before attempting to use it, and I'll switch over the formula board around June when we get into the light summer winds where I need my 8.0 or 9.5 more often.

Surfski kayak downwind paddling session

Yesterday I got some video of paddling in the ocean on my Nelo 560 surfski kayak, with a GoPro camera mounted near the stern of the kayak. The mount should be a bit higher to get a better perspective, and my stroke technique needs a lot of work, but overall I'm pretty happy with how the video turned out. Also the session was a lot of fun. :)

Should people be scared of the political left?

It seems like a lot of my fellow Americans, especially those who lean right in their political ideology, are terrified of SOCIALISM (or whatever they think socialism is) above almost all else. Some are convinced that we're on the verge of plunging into a dismal and oppressive communist dystopia like Stalin's Russia, and that even the most benign liberal policies like funding public schools or healthcare are pushing us down that slippery slope to the gulag. Others don’t go quite that far but are nevertheless convinced that any restraints on big business and the wealthy, or mercy for the sick and the poor, will lead to moral decay and economic collapse. Only ruthless, unfettered capitalism can prevent corrupt lazy losers from taking over and turning us into the next Venezuela, right? SIGH.

It's a testament to the power of propaganda that the GOP has been able to stoke this inordinate terror of the left at the very same time that their own party is engaged in alarming attacks on American democracy itself. I won’t get into all the details of the right’s voter suppression, gerrymandering, purging truth-tellers and protecting liars within government, pushing conspiracy theories about a “stolen” election, encouraging armed insurrection, etc. Let it suffice to say that under Trump, the GOP have come perilously close to achieving an "autocratic transition" - a switch from democracy to dictatorship. Yet, most conservative people still see Trump as a savior and not a threat.

Indeed, it’s ironic that these 70ish million conservative Americans; folks who are earnestly patriotic and scared of losing democratic freedoms, have empowered an authoritarian strongman who closely resembles the freedom-stealing autocrats they revile; the power-mad charlatans who’ve led their countries into dysfunction, disgrace, and worse. Trump’s macho image, his appeals to the grievances of “the common man,” his fiery demagoguery, his scapegoating of foreigners and minorities, his constant lying, his efforts to control the press and suppress the vote, his ostentatious wealth and trophy wives, his nepotism, and even his bizarre hair and style, all PERFECLY fit the mold of a dictator. Cuba’s Castro, Venezuela’s Chavez, North Korea’s Kim, Libya’s Gaddafi, Russia’s Stalin, and even Nazi Germany’s Hitler are cut from the same cloth as Trump. How is this not obvious to those under his spell?

I think the failure of so many to see the obvious has to do with how we have confounded the left-right spectrum with other types of societal variation. (In this context, “confound” means to mix something up with something else; to fail to recognize them as distinct things, like thinking that “hot” and “spicy” are the same thing.) Some other dimensions of societal variation that can get wrongly lumped-in with the right-left spectrum include autocracy-democracy, corruption-integrity, wealth-poverty, and dysfunctionality-functionality. All those things greatly affect the quality of society, and they can vary *independently* of the left-right spectrum. For example you can have a left-leaning society that is autocratic, dysfunctional, and poor, like Venezuela or North Korea, but you can also have a left-leaning society that is democratic, functional, and wealthy, like Norway or New Zealand.

Anyway, when we develop a blinding commitment to a right- or left-wing idealogy, many of the real complexities of the world collapse into an oversimplified, “right is always good, left is always bad” kind of thing. Our tendency to latch onto certain simplified views is a natural response to living in a scarily complicated and often hurtful world. For example, it’s totally understandable that someone who grew up under a left-wing dictator like Castro would associate socialism with corruption, oppression, and poverty, and would be generally averse to the political left. And of course, American politicians on the political right are in no hurry to disabuse Cuban Americans of those negative associations. Unscrupulous people love to take advantage of our oversimplifying tendency. They get us all emotionally riled up about something that genuinely concerns us, but then they hitch our fervor onto a dubious agenda that serves only them. Regardless of whether we’re tricked into the oversimplifying or we do it to ourselves, our confounding of left-right and right-wrong leads to all sorts of trouble, including:

1.     Failing to recognize and address problems like corruption and incompetence when they’re coming from our own side of the left-right spectrum.

2.     Reflexively rejecting anything and everything we associate with the other side of the spectrum, even if it might be beneficial.  

3.     Uncritically accepting lousy people and policies just because they’re under the banner of right or left that we’ve pledged to.  

4.     Thinking, “if right is good, further right must be better,” leading to extremism. (Or the same thing but with left.)

5.     Believing lies or baseless conspiracy theories about the other side because they fit in with our feelings and ideologies.

The way to get out of this “confounding” problem might be to increase awareness of all those other, important societal gradations besides just right-left. I think it would be especially helpful to recognize integrity-corruption and democracy-autocracy as important societal variables separate from the right-left axis. Autocracy and corruption are not endemic to left-wing societies. They can absolutely afflict right-wing societies, too, as folks now suffering from oppression in Turkey, or Saudi Arabia would attest.  

 There’s a kind of X-Y plot called the “political compass,” which has an up-down axis as well as a left-right axis, and which is accompanied by a quiz that places you in one of the four quadrants based on your personal views. https://www.politicalcompass.org/about On that, typical, political compass, the up-down axis is designated as “liberty-authority,” and it helps distinguish libertarians from classic conservatives, democratic socialists from authoritarian socialists, etc. That helps a little with the “confounding” problem that I’m talking about, but it’s not quite what I’m looking for. I think it would be more useful to make the up-down axis be more clearly a good-bad axis, with something like “functional democracy” at the top and “corrupt dictatorship” at the bottom. Then you could put different countries that we’re familiar with in the different quadrants to better illustrate that both right and left can fall into corrupt dictatorships.

Rough draft diagram-














Final thought: I’ve said that many important aspects of societies, such as integrity-corruption and democracy-autocracy, are independent of the left-right spectrum. An implication of that is that we do not need to be inordinately afraid of moving right or left, as long as we’re watching out for those other aspects of how society can go good or bad. However, I do think there is some danger of going to the EXTREMES of right or left because an extreme philosophy is more likely to get blinded to the other nuances.

Windsurfing edge of TS Eta, Lovers Key, FL

Most of my windsurfing lately has been on the hydrofoil since we haven't had enough wind or waves to justify getting the traditional shortboard gear out. That changed a few days ago though, when Tropical Storm Eta brought some BIG wind from the south, and big swells. The Gulf of Mexico looked really ugly at most of the potential launches. However, by launching at Dog Beach on Lovers Key, and sailing out through New Pass (an tidal inlet protected by two sandbars) I was able to get into the waves without dealing with any shorebreak or sketchy longshore currents. I used a 4.2 sail and a 106 liter Exocet Cross. It was easy to get out on that, but I was over-powered and over-boarded in a way that made it tough for me to carve on the waves. So no major tricks or anything that I can brag about. I still managed to get some video that shows the condtions.

Sloppy stars surfski kayaking practice in the ocean

I have a new-to-me surfski kayak that is fast but quite tippy in rough water. It's a Nelo 560.



To improve my rough water balance and comfort level for the October 3rd Key West Classic race, I've been deliberately paddling in the ocean at odd angles to the wind and waves. (It's not THAT hard to go straight upwind or straight downwind, perpendicular the bumps, but getting the waves from the side and at oblique angles is quite tricky.) I've sometimes done a workout like this as "sloppy squares," drawing boxes with my path, but I changed it up this week with what I'm calling "sloppy stars." I program the workout in my Speedcoach GPS as 10x800m with no rest between the segments, and then I just have to estimate what angle to go at and remember to always turn left at the end of each segment to make the star pattern. I'm pleased with how this turned out.
