Wimmin on sailboats

Amfortas is a kindly soul and he’s contributed this to the topic of live-aboard boats:

I know that clip and she has a well set-up boat, she still needs supplies but she’s semi-self-sufficient, which is a good way to be.

He then also sends some piccies. The Laura Dekker ones I have on file and more – it’s a bulging file but a couple are included with pics I’ve not seen, all affirming the joy of sailing:

Laura Decker and that girl in the clip know just what sailing can do to a soul, as distinct from powerboating. There’s a sort of symbiosis with nature involved.

Methinks one day Laura will, in conjunction with her father, build the next Guppy. They certainly rebuilt that one and far from the perception that Laura just ‘assisted’, she had a major hand in what went onboard and where.…

Boat – the circuits

Very, very rough diagram, with Paint and GIMP the only graphics programmes onboard:

 

circuits roughly

Notes

1.  The philosophy is twofold:

[i] to keep AC, DC, house lights and outboard entirely separated;

[ii] to minimize power when mechanical will cover it.  No servos, inverters etc.

Generator is earthed [or watered] via metal strip.  Outboard earthing is taken care of by manufacturer.

2. Regs say Gen, Battery and OB must all be outside cabin by at least 1 metre. First two have own storage lockers, with run-off and ventilation.  Outboard is covered and secured.  Gen only used  on open to the sides part of  cockpit which has roof.  Refuelling by putting on towpath first.

3.  As you see by the diagram, I’m no electrical engineer but one can’t be all things.

4.  Houselights have their own batteries and wind-up mechanisms and I’ve been using these at home – they work.  It also applies to heating, which is battery driven pads inside sleeping bags.…

Boat

Amfortas kindly sent me this:

… and this:

… and I didn’t respond at first, as I didn’t see where it fitted in initially.  So I had to look at the long term plan.  There are two phases for the boat.

As a canalboat

No need for navlights, so cooking is initially via generator powered AC devices and later gas canister stove, houselights are individually powered by batteries – I’ve tested these already and they work well, give long hours in LED -two lanterns are wind-up type

As well as the generator is the outboard at a pinch but I don’t want to rig that up and compromise it.

Water is via the 100 ten litre water carriers I have – one has been sitting there full for two months now – and that supplies me with enough ballast for the boat too on the canal [to stop rocking].  Remembering I have four pontoons supporting the sides as well.…

Spycam on the past

rue toilets

Not at all sure why Google do a streetview photo as well as a map.  I mean, what do you need the streetview of the houses for?  Just the sheer work involved in photographing every street in the world is mindboggling.

And the most frustrating part is that the bit you want to see is obscured by trees or a billboard and you only get this close and no more.  It creates a longing and can also shock you when things which used to be there are no longer.

This all started through Harold Holt’s disappearance, part of last evening’s post on Gough Whitlam. So I went to Google maps, didn’t I and looked back at places in the area I used to frequent, maybe in what must have been from the late 60s to the mid 70s, after which I returned here.

And we would camp down there on the Rye foreshore in summer but now it’s just a park – I knew that anyway, that they’d cleared away all the summer campsites but was still hoping to see the pier.…

Christopher Wren

Still on the sailing theme:

SUBTUS CONDITUR HUIUS ECCLESIÆ ET VRBIS CONDITOR CHRISTOPHORUS WREN, QUI VIXIT ANNOS ULTRA NONAGINTA, NON SIBI SED BONO PUBLICO. LECTOR SI MONUMENTUM REQUIRIS CIRCUMSPICE Obijt XXV Feb: An°: MDCCXXIII Æt: XCI.

which translates from Latin as:[12]

Here in its foundations lies the architect of this church and city, Christopher Wren, who lived beyond ninety years, not for his own profit but for the public good. Reader, if you seek his monument – look around you. Died 25 Feb. 1723, age 91.

His obituary was published in the Post Boy No. 5244 London 2 March 1723:[13]

Sir Christopher Wren who died on Monday last in the 91st year of his age, was the only son of
Dr. Chr. Wren, Dean of Windsor & Wolverhampton, Registar of the Garter, younger brother of Dr. Mathew(sic)
Wren Ld Bp of Ely, a branch of the ancient family of Wrens of Binchester in the Bishoprick [sic] of Durham
1653.

Twitter’s turned out to be a nice source of pics and it’s all whom you subscribe to.  No different to which newspapers and magazines you choose to read.  As with the internet, there is unmitigated dross, e.g. Ferdinand but there are fine people too and buffs of all sorts of technica.

Usually the explanations are there in links but I confess I just grabbed these pics and did not note down the details.  Still, they’re interesting:

Strictly sleazy: How the perfect family show’s romantic elegance has given way to raunchy routines and ever more skimpy outfits 

Yep, it’s become no more than a show for grotesque slappers who hoof around in as masculine a way as they can, with aggressive gestures meant to pass for their version of femininity. Strictly not a dance programme.

Bite the hand which …

So this woman comes over here and enjoys our hospitality for years, then repays the country by scheming to remove the Elgin Marbles. Nice person. They speak of the jihadists having passports revoked …

They have a point

After Scottish independence vote, separatists say Britain reneging on pledges 

Well, of course Cameron reneges – this is his stock in trade.  He no further will withdraw from the EU but he loves gay ‘marriage’.

The important things …

Wiggia:

A husband went to police station to report his missing wife:
Husband : I’ve lost my wife, she went shopping yesterday and has still not
come home.

Plane, car, boat

There are just enough people or so it seems who are interested in these design issues with the boat, so here goes an explanation of when there’s choice and when there’s not.  My bit’s further down.  Let’s group our transport thingies together today, quite a few of them:

Plane

From a Volvo supercar to a mega-Ferrari. Whatever next?

Boat

Rossa sent this:

http://www.dailymail.co.uk/travel/travel_news/article-2790804/private-yacht-shaped-like-star-designed-lobanov-design-bmt-nigel-gee.html

… and I’ve just attacked it as a design:

First thought utterly unstable.  I don’t mean it would turn over but it would always be on an angle.  Guests would be walking upward all the time.  This is the nature of the yacht.  And without power, it would go nowhere – it has an engine at each end but the props look like they’re just auxilliaries.  Better were those floating islands.  They always moored head to wind and the beach deck was behind.  Shall make a post of these two.

One for the boys and lady petrolheads

Car

Rossa is no shrinking violet and she sends the latest news on the new Interceptor.

new interceptor

An all-new version of the Jensen Interceptor will be unveiled late next year – and it will be engineered, developed and built by British specialist automotive group CPP.

Healey Sports Cars Switzerland, which owns the Jensen brand, has appointed CPP Global Holdings to develop a modern-day version of the Italian-styled, West Bromwich-built Interceptor grand tourer, which was built between 1966 and 1976.

The car will be a four-seat GT, like the original version. It will be based on an all-new aluminium chassis and handcrafted aluminium body.

Boat

In other semi-vehicular news, I’ve made the decision to go from three to two masts on the boat and that’s why I left the mast step until now to put in, plus the structural work underneath.

The three mast rig was excellent – it comprised [from the bow] a jib, fore gaff sail, main gaff sail, mizzen bermudan sail.…

Tesla pulling the lower limb?

Haiku sends El Reg:

Tesla Motors has revealed a dual-engine, 691 HP, all-wheel-drive version of its model S.

Launched at an evening event in Los Angeles on Thursday by CEO Elon Musk, who explained that the rumoured “D” stands for “dual” as the car has two electric motors: one at the front and another at the rear.

Musk told the event that the car’s software “dynamically shifts power from front to rear at millisecond level.” This arrangement, he said, is better than conventional all-wheel-drive systems because it directs power to where it is needed, when it is needed, leaving the Model D “inherently able to do better road holding than cars with a single engine.”

“Acceleration is a bit faster”, he added, with zero to sixty miles an hour achievable in 3.2 seconds.

Poachable [haiku]

http://lifehacker.com/poachable-lets-you-look-for-a-new-job-anonymously-1644022115

Poachable works kind of like a dating app—it’s all about matchmaking. First, you put in all the vital information regarding who you are, your current job, and what kind of work you’re interested in. Then the service scours the web for job opportunities that match the data you input, and then lets you know what might be a good match. In Tinder-like fashion, you say “maybe” to the matches the service finds, and then the service passes along your information—sans any personal info—to the employers you gave a “maybe.” If the employer expresses interest as well, the service sets you up with a proper introduction.

Which car IS you?

Der neue Volkswagen Passat

We went looking for cars the other day, not far from Manchester and one of the things we were discussing was ‘which car IS you’.

Just been looking at the new Passat at the Telegraph.  Very nice, not very exciting, does the job, ticks all the boxes.  You buy this big touring car and reasonable town car and you’re not an unhappy driver.  Everything you need – carry the family, tour, go from A to B – it does it.  Retains value, shows you to be a discerning person.

Just not me.

Love Tom Paine’s Speranza [hope he doesn't kill me for  stealing the pic]:

Fabulous machine, like the one he had before it.  Good taste, Tom.  Here’s his philosophy:

I steer well clear of models (e.g. any kind of mommy van) favoured by the “It’s only to get from A to B” brigade. Their lack of enthusiasm for cars and motoring is bound to be reflected in their performance.

What the perfect man drives

Press release from Europcar

The Perfect Man can change a tyre!

Prestige from Europcar research reveals the traits of the perfect man – at least as far as his driving is concerned!

www.europcar.co.uk

  • 22% of women see the perfect man driving a convertible
  • Only 3% see them driving an estate
  • 53% want a man who travels in his leisure time
  • Over a third say the ideal road trip is a drive along the Amalfi coast in a convertible

London, September 2014 – Europcar, the leader in car hire services in Europe, has conducted a piece of light-hearted research* to find out about the driving traits of the perfect man – at least as far as women are concerned!  More than 1 in 5 said they see their perfect man driving a convertible. Audi was the top brand for all types of car.  And when it comes to the perfect motoring getaway, 35% voted for a trip along the Italian Amalfi coast in an open top sports car.…

Reasons to be wary, part three

Online hacking of shoppers:

The Home Depot is only the latest retail chain to be hit by massive security leaks. In late 2013, Target was hacked, and information about 40 million credit and debit card accounts was compromised. Security researcher Brian Krebs speculated that the same hackers carried about both hacks. Either way, it appears that Target’s misfortune was not enough to convince every company to audit their own security systems.
