Netanyahu's party claims Israel's election was stolen.

Sound familiar?

An incumbent attempting to establish a false reality through accusations and loud repetition. These people don't get embarrassed.

Unmanned Vessels--Would You See This?

I've been reading forum posts by sailors concerned by the increase in unmanned monitoring vessels. This concerns a collision on Lake Erie. The NTSB has recommendations for improving the safety of such operations. What bothers me is that they assigned no responsibility to the powerboat that ran down what could have been a kayaker. It was daylight, and the drone was transmitting AIS, which the powerboat was not monitoring (not required, but it was a 45' boat moving at 25 mph, which in my mind, increases responsibility).

 Read the report. Reach your own conclusions.

NTSB report 

 ----- 

 A small excerpt from the NTSB report, MIR-26-32.

... While the USV was underway near the WE08 site, the recreational vessel owner
was transiting back to Safe Harbor Toledo Beach on a southwest heading at cruising
speed (about 25 mph). Having owned and operated vessels in the Monroe area for
over 20 years, the operator had a thorough understanding of the area and was
navigating his vessel visually. Although the sun was positioned at a low angle in the
western sky off the starboard side of the vessel, the operator told investigators that
the sun was not impairing his vision. He stated there was about 2–3 miles of visibility.
 

With an overall length of 15.7 feet, the USV had a similar length to a small-sized
recreational vessel such as a kayak, canoe, rowboat, or powered skiff. The USV had a
yellow hull, meant to help make it more visible to other vessel operators. However,
due to the vessel’s design, only about 1 foot of freeboard was visible. Additionally,
most of the main deck was covered with solar paneling, which was dark in color, thus
obscuring the vessel’s yellow coloring and making it blend in with the surrounding
water. At the time of the collision, waves were 3 feet, which would have intermittently
obscured the USV’s hull as it dropped through the troughs of the waves and made it
difficult to discern the USV in the water (figure 15 shows the vessel underway in
similar wave conditions). Further, most of the USV’s hull appeared dark yellow when
viewed from the side, as the vessel’s design cast a shadow on the hull....

Winter is Coming

 I previously posted lead-acid battery voltage vs. temperature and state of charge (SOC).

 

If you have switched to lithium iron phosphate, there is also a relationship between temperature, voltage, and state of charge. The drop is less, but remember that lithium cannot be charged below freezing and the battery management system (BMS) will disconnect the battery from charging below about 35F. Additionally, the BMS will disconnect the battery completely below 11.5 volts (typical setting) until charging current is applied and the battery rises above 11.8 volts (typical).

 

 

I installed a Li-Time battery (weight savings, price, and the lead was dead) and I have experienced both sorts of cut-offs (very low slow solar through the winter, and charger failure). In both cases, the battery woke up when charging was applied.

 

 

Childs Hill, A Grown-Up's Mountain

 I'm quite sure I will not reach the summit, but I toil on the slope. Sailing. Shop skills. Engineering skills. The view is improving every year. As for understanding people and cultures, I'm not far above the canyon, but at least I know that.

 

 

Trump Aranges Deal for Rusian Diesel

A coward. A corrupt politician trying to sway an election. Un-American. A humiliation to the Republican Party. A humiliation of the Republican Party. Please count the American servicemen's lives that have been spent and lost in the fight against totalitarianism and communism. Trump spits on our brave men. He likes Putin because he is like Putin.

There aren't enough words for a worm like this. Further, the entire Republican Party, every Representative and Senator, has made itself culpable. No blame-shifting allowed, when you support such a man. You are hiding behind such a man.

Keeping the Gasoline Tank Cool (And protected from UV)

By law, above-ground gasoline tanks are ALWAYS painted white or silver. This minimizes solar heating and thus minimizes day/night breathing emissions. I'm a tank inspector from way back. I had a consulting business, and I've been around, over and in thousands of tanks, from 500-10,000,000 gallons. 

 E10 loves to absorb water from the atmosphere. If the water content reaches about 0.5% (more in summer, less in winter), the water will separate, taking the alcohol with it and creating a 15%-by-volume layer that won't burn. Phase separation, as this is called, is very unusual because absorption from the air is a very slow process, taking months. The usual cause, in fact, is a leaking filler cap or vent, not absorption.  It's a slow process, taking months to become important. But prudence requires closing the vent whenever the engine is not in use. Spray can sneak in through the vent.

Water absorption does NOT need to reach phase-separating levels to cause problems. At just a few hundred ppm, sludge generation increases. The gasoline becomes weakly conductive and galvanic corrosion blooms in the carb bowl (brass and aluminum are an active pair). Gasoline also evaporates, and the loss of the most volatile portions can make starting more difficult, and increase gum formation. Better to keep it sealed. 

But a sealed tank builds pressure. Over time, UV damages the tank and the tank becomes weak.  It would be nice to keep it out of the sun. Some people like Sunbrella covers. But on my boat, it would just get grungy with spilled oil, gas, lichens, and algae. 

 Paint is simpler. Since the tank is mostly covered by the seat, there was no need to paint the whole thing. If it was, I might paint the whole thing, leaving only the code stamp exposed (not on a seam).

Simple. The tank is protected from UV and stays cool. It's been seven years, 365 days per year, and the paint is still there.

  

Tiller Pilot Cover

 The leading cause of death for tiller pilots is moisture intrusion in the rain. In the UK they are common on eBay, but not here.

 A few days ago I had to take a 4-hour rainy sail to move my boat between marinas for service. After three years (Total Boat Krypton) the bottom needed anti-fouling paint, and Herrington Harbor North has decided that hauling trimarans scares them, so they won't do it anymore.  

So when the rain started, I pulled out the cover I had made from a scrap of clear vinyl snipped from an old dodger.  No sewing was required. I just folded it, somthing like wrapping a box, and popped a rivet in each of the corners. The bottom is open for ventilation. The tiller pilot stays bone dry, since it produces a small amount of heat in service, sufficient to prevent condensation and evaporate any stray drops.

You can see the buttons and use them right through the vinyl. Very easy.

Public Service Anouncments in the Election Cycle

No, they are not, Donald. These are taxpayer-funded election ads. 

This is how tyranny starts. He read the tyrant's handbook and memorized it. Please watch this docuseries on Netflix. It is an excellent history of tyrants, starting before Rome, moving through Hitler, Qaddafi, Idi Amin, North Korea, and forward. It is not about current events.

Reporting in the White House

 

 

Does he even think about what he says?

 “There’s something wrong with a country that can allow people to write purposely negative stories,” Trump added. “Now, if they want to write them, that’s fine, but I don’t have to let them into my, into the people’s house.”

 No, Donald, it's not your house. You are a guest.

And the Justice Department, the toadies they are, can seem to do much better.

"The Justice Department urged a federal judge to keep CNN, Politico and MS NOW reporters off White House grounds, arguing that President Donald Trump may restrict their access over national security concerns ..."

Let's focus on "security concerns." Either (a) your people are releasing classified information, which is both unlikely and also an internal problem, or (b) the press saying negative things about the administration is treasonous, simply because they disagree with you. Really, it is the latter. You could argue that making the country sound divided and mentioning potential weaknesses is bad for national security; but this forces the leap to saying the administration has the right to control the narrative in all things, and that takes Donald so far past the First Amendment it's just criminal.

I hope this goes to the Supreme Court. He'll get stomped. I've seen a lot in the prior four-year term, and even more in the past 20 months, and this once again goes beyond the pale. The President does NOT get to control the narrative. If he can't take the heat, that speaks to both megalomania and clinical narcissism.

 Say what your think needs to be said.  Check your facts, and then say it. I wish I could keep this a strictly-sail blog, but I've got to say what I have to say. We have a rogue administrator with unrestricted power. A tyrant that believes he is unbounded by law.

  

 

Big Oil

1. An invasion/interference in Venezuela.  An oil deal in progress. Venezuela has 17% of the world's reserves, more than any other country. Not great oil, and hard to get to, but we will.
2. A war that closes the Straights of Hormuz.
3. A war that closes the Bab-el-Mandeb (Red Sea). The US had forces in position that could have impacted this quick movment, but not one strike was made. Either a major f__k-up, or intentional. Too major, I think, to have been accidental.
4. Conversation about ending the war very soon. I'm thinking that is because our objectives, items 2 and 3 above, will be complete.

And so a large portion of the world's supply of oil will be constricted, possibly for decades. 

• Iran is not defeated but rather enraged and positioned to choke the straits. Drones will make it easy.
• By military arm-twisting and bribery, we will have secured oil from Venezuela. 
• The price of oil will soar, allowing Big Oil to print money. Yes, we could restrict exports, but the administration has made no effort to do that and will not. 

This, by the way, is part of why the war in Ukraine was not interesting. No benefit to us. Even among liberals, I think there is a sense that this is Europe's problem first, ours only second.

The business in Gaza is nuts, from the music festival start to where we are now. I think the timing was convenient for the above "conspiracy theory," but probably only that.

Pipelines will be built to the Mediterranean. That will take time.  The straits will become less relevant within 2-5 years. Some already exist, and I am sure they are looking to upgrade this capacity. Not so good for China, but they will find a way.

So is my Big Oil conspiracy theory good for the US or not? It's not nice or globally neighborly, but financially, it's not clear. It depends on how you are invested, to be sure, and how you are employed.  Some benefits will spill beyond big oil, and fuel prices will be up for a while.

But I don't see current events as random.  I see greedy, certainly corrupt, politics. We elected a casino guy--what should we have expected?

Today Trump asked the Ukraine to stop targeting Russian diesel production. It could cause a shortage. Isn't the hypocrisy in that just mind rattling?  Another example of "watch the shiny ball" to distract people from the important stuff. Unfortunately, there are gullible people.

Yes, I am posting more politics. Free speech.  What happens when the people do nothing and say nothing? I hope to get back to sailing and tinkering. I'm retired now. That is what I should be doing. But it's raining today.
