Enlightenment

Many years ago, in a Grade 7 or 8 Social Studies class, Paul Kardash spoke some words which have stuck with me ever since.  Their longevity has more to do with their incongruity than their insight.  “One day Buddha was sittin’ under a tree when enlightenment come to ‘im”  Words that only a barely literate Ukrainian history teacher could ever formulate but a memorable quote nonetheless.  Well, yesterday Bob was sittin’ on his boat when enlightenment come to him too.  Twice.

We left the boat unplugged this summer so the first thing we did when we got back onboard was to plug it in and then turn on the breakers.  We have a kind of flaky “system” for our air horn which involves a pancake air compressor running off AC.  It works reasonably well and gives us a very loud horn but its a kludge.  When I turned the breakers on of course the compressor started up.  It sits on the flybridge under the forehead so its pretty loud in the cabin because it runs directly over our heads.  It used to really bother the damncat.  When we arrived on Sunday it ran and ran and ran and ran so eventually I went up top and unplugged it.  Yesterday I resolved that problem which turned out to be simply that I had left a garden hose attached to the compressor.  We used the garden hose to blow the lines before we left the boat.  No big deal – smallish enlightenment.

The other problem was more serious.  We have a 48 volt bow thruster.  Its a pretty good thruster – hydraulic would be better but high voltage is good.  The 12 volt thrusters are pretty well crap – they simply can’t draw enough amps for long enough to do anything useful.  I’ve seen lots of 24 volt units and they have a decent reputation.  Ours is the only 48 volt system I have ever encountered.  The advantage of a hydraulic system would be that you could lean on the control and leave it on all afternoon without it ever letting up.  We can thrust for maybe a minute at a time before it starts to run the batteries down. 

I’m getting close to ready to fire the engines so I was trying the rest of the systems yesterday.  When I tried the thruster I got nothing.  No little light, no thruster noise and when I checked the batteries, no voltage.  Seriously not good in other words.  The way the system works is that we have 4 x 12 volt batteries wired in series to run the thruster.  They are charged by a great big heavy 48 volt transformer that runs off 110 service.  Underway the transformer gets its power from the inverter.  The transformer is only 2 years old but when I tested its output I got nothing.  That kind of pissed me off because I just replaced the damn thing 2 years ago.  As it turns out I likely didn’t need to do that but its too late now.

When I was about 8 years old I tore apart a windup clock to see how it worked.  I couldn’t put it back together and went to bed in tears but by the next morning father had put it back together.  As a result of father’s kindness (and no doubt some serious late night frustration) I never really learned anything from the experience.  I’ve never been shy about tearing things apart since – lacking father’s assistance to restore them to working order overnight I sometimes regret my enthusiasm for disassembly but I continue undeterred. 

I don’t really know jack shit about electronics but I figured the transformer wasn’t working anyway so what did I have to lose?  When I got the covers off it was a lot more complicated than I was expecting but I was able to recognize the output windings and when I measured the voltage across them it was around 93 or 94 volts AC.  That seemed to me to be about what it should be.  I recall reading somewhere that AC output will be slightly less than twice what the resulting DC voltage will be after it is rectified.  48 times 2 would be 96 so 93/94 volts seemed reasonable.

The rectifier circuit board looked OK too – no burn marks, no exploded capacitors or corroded connections.  It has 2 medium sized transistors with big heat sinks that clearly do the rectifying but it also has a bunch of other smaller wires coming off the board and leading back to the input circuit board.  That’s when enlightenment come to me.  For some reason it occurred to me that perhaps the output circuitry was watching for voltage on whatever it was supposed to be charging in order to turn itself on.  Clearly the transformer was putting out power – I could measure it, I could hear it humming and it was slightly warm to the touch.  That power just wasn’t making it through rectification to the output wires.

So I ended up kludging everything back together in the engine room with a couple of leads hanging out connected to the output side of the transformer.  Then I jump started those leads to the 12 volt engine system.  There was a great big spark when I did that, likely because the depleted batteries would look like a dead short.  However when I tested the voltage on the dead batteries after the spark, sure enough they were reading just over 5 volts.  More usefully that 5 volts slowly climbed to over 6 volts and then declined to under 3 volts.  I left it alone for a few hours and the next time I checked it had climbed to 54 volts.  I haven’t checked it again this morning but I expect it has stabilized somewhere over 50 volts. The little green LED on the transformer also came on and stayed on.  The lesson learned is that likely the transformer I threw out 2 years ago had nothing at all wrong with it.

Re-adjusting to life afloat

This morning I launched the anchor again.  I like to pull it before we leave the boat because it hangs way out over the dock and I’m afraid someone will bang their head on it.  When I pulled it in July it was so I could take the bow roller back to the prairies to rebuild it.  Over the past couple of days I got all that new stainless mounted with some very expensive SS bolts.  Over 5 bucks apiece for the 6” bolts and over 4 bucks for the rest of them.

After we got the anchor lowered overboard I pushed the button on the windlass and it came back aboard just as easy as can be.  That’s a huge improvement over the old method where I had to perch out on the bow pulpit to help the anchor over the hump with a boat hook. 

Next step is to fire up the old Lehmans and the antique Onan.  If all that goes well I think we’ll take the boat over to the club on Wednesday afternoon.  We’re the featured attraction at the speaker’s seminar Thursday evening.  Our topic is “Cruising Offseason to Alaska – What Were we Thinking?”

The view from the left coast

coldest-year-in-10000

2014 was either the warmest year in the past 100 years or among the 3 coldest years in the last 10,000.  Take your pick.

I’ve been having a lot of trouble with that “warmest in the last 100 years” claim which has led me to a variety of websites.  The problem with the warmest claim is twofold:

  1. Its presented as confirmation of anthropogenic global warming – warming caused by man’s emissions of CO2 in other words.  But even if it actually is a warmer year, it doesn’t by itself confirm anything.  And as I am about to argue, its not actually the warmest year in the last 100.  More importantly the current measured temperatures continue to stubbornly diverge from the alarmist  predictions of the warmists.  In actual fact the so-called warming trend has been in a 20 year pause now.  GlowBullPause
  2. Independent of any AGW causation, the measurement itself is suspect.  Whenever you do a measurement you have to consider the margin of error.  If you measure something by pacing it off with your feet you wouldn’t subsequently claim that the distance was exactly 6.37283013 feet.  (or maybe you would in which case everyone who saw you take the measurement would immediately assume you were a fool)  In the case of the “warmest in 100 years” claim, the margin of error is reported as 1/10th of a degree but the margin of warmest is reported as only .02 of a degree.  In other words the margin of error is 5X as large as the difference reported.  The claim is every bit as bogus as you reporting an 8 decimal point distance by stomping it off against your shoe.

This information is not immediately popular in our current locale.  Try to imagine my dismay.

Red Radio

We must be back in BC. They've already apologized for Islam and trash talked the 1%. All that remains is the (mandatory) daily queer segment. Apparently if we distributed wealth evenly that would be better because everyone could (more likely WOULD) then spend their wealth. They didn't elaborate on exactly where those newly affluent consumers were going to do their consuming in the absence of capital accumulation.

Oh well. At least it's not 90 below zero with a wind blowing.  It is raining mind you.

Torturing the language

……… in the name of political correctness.

So this morning a couple of thugs have taken some hostages somewhere in France.  The media has jumped all over that because France is the topic du jour.  Two weeks ago a hostage taking in Montreal wouldn’t have made the national news, let alone one in far away France.  The big debate on the TV this morning is whether this latest hostage taking is “terrorism” or just a regular garden variety kidnapping.  I expect it is terrifying enough for the victims, no matter whether their captors worship Allah or God or pink lizards.

CrescentStarWhat’s bugging me this morning is the phraseology we use to describe these incidents.  What we’re talking about of course is Islamic extremism or Muslim terrorists.  Everybody knows that.  “Terrorism” has become code for Islamic extremism.  Despite that we could never admit that there may be a fundamental problem with Islam, that would be xenophobic or racist.  I heard an argument the other day where one person opined that the violent incidents we are seeing are caused by a few bad apples to which his opponent responded that, given the number of bad apples we are seeing, perhaps there is something rotten in the orchard.

We don’t have to live in fear.  We REALLY don’t have to live in fear out here in Buchanan but as a global society we don’t have to live in fear either.  We do have to name the threat and so far I see absolutely no willingness to do that.

We are INVINCIBLE

The trunk of the car is mostly full – there’s more room left than I expected but I’m sure there’s more left to put in it than I think too.  All of a sudden today a snow storm appeared in the forecast for Revelstoke.  I’m dunno where the hell that came from – the weather has been uniformly good from the coast all the way to Calgary for close to a week now.  But all of a sudden this morning they started showing heavy snow for Revelstoke on Sunday morning which is exactly when I expect we will be passing through Revelstoke.  Fortunately it is not a problem. 

Thanks to the geniuses in Victoria WE ARE INVINCIBLE.

I haven’t been able to get the Black Knight sketch out of my mind ever since we started into this winter tire bullshit.  We may however hole up in Golden for a little longer than we otherwise would have.  Or the weather forecast may be wrong.  Hard to imagine I know but I hear that it occasionally does happen.  Or maybe these new tires really will make us invincible although, as SWMBO just pointed out, every other idiot on the BC highways will now also think that he is invincible.

Well …. that was complicated

…….. way more complicated than it needed to be.

As I wrote about here, the nanny state assholes in Victoria have decided that drivers in BC are too stupid to make intelligent decisions about winter travel.  By the time I wrote that post I had called the tire shop in Preeceville and ordered 4 tires mounted on 4 new rims.  No problem – he’d call me as soon as they were ready – likely about 10 days. 

BullshitWinterTires

Its almost exactly a month since that first call and I only got those tires mounted today because I have been hounding the tire guy since last Monday.  His attitude completely baffles me.  When I finally got inside his shop today he was as friendly and efficient as he always is – I was in and out the door in under 45 minutes.  The only thing that took any time at all was persuading the Lincoln to air up the bags enough to lift the car off his jack when I was ready to leave. 

For the period in between the phone call and this afternoon however it was as if he really didn’t give a damn whether he had my business or not.  He simply never phoned me back, no matter what commitments he made to do so.  Every time I phoned him he’d put me off for a week with some story and a promise to call me.  Then about 10 days later when I realized that he still hadn’t called the whole cycle would start over.   I last talked to him Thursday afternoon when he assured me that the rims were coming on the bus that evening and he’d have them ready on Friday.  He didn’t call Friday or Saturday so I called again this morning.  At that point he said it would be another couple of days because “he had to make a trip to get the tires”.  I didn’t completely lose it but I was pretty firm when I pointed out that on Thursday the story had been that the rims were arriving that night and he had claimed all along that he had the tires on the shelf.  That got me a commitment to get the tires mounted and balanced this morning but I was sceptical so I called again at 11:30 to confirm and in between I phoned every tire shop within 60 miles to see what other options I might have. 

Strange. Very strange.  Meanwhile the tires work like any other tire I have ever owned – they go around.  I don’t buy into the government bullshit which assumes that because I have winter tires I am somehow immune to winter driving conditions.  Our departure and travel times will still be governed 100% by prevailing weather conditions.  So far it looks good for a Saturday departure but 5 day weather forecasts are almost as full of bullshit as BC tire legislation.
