    That's what I do. I leave her afloat and go out for at least a long weekend at least once a month over the winter. I have come to love sailing in the winter.

    I think that being afloat is much gentler for the boat than being ashore. I have never drained or winterised anything and never had a problem.

    On the other hand, I was always in a marina with shore power so that I could keep electric heaters going on board. I am now on a mid-river pontoon without shore power and am wondering how to deal with that.

    However...GLOBAL warming (due to natural blips in the climate) means that the North Atlantic Drift will wiggle about a bit. This means that the nice warm water that stops us freezing goes somewhere else and we get cold. It probably bu99ers off somewhere else to avoid arguements on here that dont see the bigger picture
    So how does this North Atlantic Drift explain the record cold winters China has had in recent years when the weather is supposed to be getting warmer? Likewise southern hemisphere countries getting colder winters and summers in recent times?

    Its a bit like when someone is ill with a fever: the sick person shivers with coldness, whereas in reality their body is dangerously hot.

    Planet Earth is like a massive body, with powerful but intricately-interconnected parts. Man's success as an overwhelming and technologically-armed plague (think of it as a virus or a disease on the whole body) has been having a steady but collossal and cumulative effect on the planet for many decades now, possibly even a century or longer, going back to when Europe's industrial revolution first got going. By pumping awesome quantities of airborne **** into its atmosphere (burning coal and liquid fossil fuels), ripping out its lungs (deforestation) and sealing huge areas of its surface (tarmac roads and concrete towns and cities), we're at least partly responsible for upsetting the balance of things.

    When a body is pushed too far it weakens and gets ill. What we've been experiencing with record extremes of temperature - both hot and cold - and unseasonal weather patterns are the symptoms of this illness.

    If a person smokes just too many fags, then they'll eventually die of cancer or heart disease or the inability to breathe in enough oxygen to support their life - not many people dispute that one. If the planet's delicate but self-regulating balance of things (cold at the tips, hot in the middle, etc) gets pushed beyond a certain limit, then unwelcome things start happening.

    When seemingly small increases in overall (not just local) global temperatures begin to result in polar ice melting a bit more each year than it freezes, this begins to mess up the old balance of ocean currents. The first warning signs are noticable changes in the weather, with record hot summers (France hitting 40 degrees in 2003, the Murray River in Australia drying up completely, etc) and very cold winters (China, Europe, etc).

    Maybe we can put these extremes down to medium-term fluctuations in the planet's self-regulating systems (like a body sweating when its too hot, or shivering to generate heat when its too cold). But - and its a BIG BIG BUT - maybe the planet is being treated a little too badly, like some idiot abusing his body by smoking fifty fags a day, or even just twenty. Relatively few people will care if the idiot gets cancer and dies (a personal catastrophy), but if the climactic changes across the planet result in an eventual but catastrophic change in ocean currents (like the Gulf Stream turning off), then never mind creeks, paddles and shyte - its going to be a problem of dinosaur-like proportions.

    Its a risk. Fag-face might just live to be a hundred and die watching Top Gear. But there's a horrible chance are that our children are going to experience awesome changes in the climate.

    If, for example, the Gulf Stream does eventually turn off, Europe will suddenly get the same climate as Alaska and will eventually cover in glaciers while other parts of the world will become just too hot to sustain human or animal life at all.

    While the planet is busy sorting itself out over a very long period of time (its a self-regulating system, always has been), people and other species are going to die in their trillions.

    Cigarette anyone? Wild sex with an HIV-carrying Bonobo monkey?

    I like your analogy. Lot of fagfaces on here.

    I gather you are a Lovelock / Gaia fan.

    Heres another way to think about it. 97% of the worlds climate scientists agree that the climate is changing, and its at least partly down to the burning of fossil fuels, amongst other things. They agree that action will help to prevent the serious changes that our children will have to deal with.

    Now if 97% of marine surveyors agreed that your stern seal was at the point of breaking, would you listen? Of course, because the chances are, that that huge majority of qualified opinions are, probably, right. Of course, the 3% who say the stern seal is fine, might also be right. But the prudent thing to do would be to take some action to change the stern seal, right? Just in case.

    Which is where I sit with it all. Newspapers and bodies of opinion have been proven to be right and wrong on all sorts of issues. But the prudent thing to do is to listen to the majority of qualified opinion. And right now, the completely overwhelming majority agree that human action is changing the climate dangerously.

    The 3% might be right. But just in case, I think I'll side with the 97% for now. After all I have four children.
    I dont know about these speed bumps. I think if anything, they slow you down.

    I'm for protecting the environment but i'm not naive enough to believe that for example, driving around in a Toyota Hybrid is going to make any difference. (in fact the opposite, if you count the total environmental cost from build to scrap)

    But I certainly agree that I think it's going to be a chilly one this year.

    Batteries off the boat sooner rather than later, empty the fresh water tanks and anything that moves, well greased.
    Certainly agree with the Toyota hybrid statement. It doesn't make sense to scrap a less efficient car for a more efficient when you take account of the energy used in producing the the new one.
    I'm just off for a spin in the moggie minor!

    Thinking again about boat batteries.... and not about specious claims about mythical scientists....

    I retained 3 batteries onboard, afloat, last winter instead of bringing them home. Once a month, or more, I used them to start and run the engine, for over an hour each time. They were recently checked and tested by a qualified specialist, who pronounced them each in first-class condition.

    I'm aware we here - near Bath - had some of the coldest spells elderly neighbours and I could remember ( this is NOT an invitation to rant on about CC/MMGW or any other recent religion ), which damaged flagstones' and boulders' surfaces. Those batteries remained in a container immersed throughout in a 'fluid bath' which got no colder at any time than +2C.

    In my 'boatshed' at home, they'd have been below -10C for several days.

    It's not a large sample on which to base conclusions, but those batteries will remain afloat again this winter unless more convincing evidence for removal emerges.

    If this were true, Luke, I would be flogging my 4x4, scrapping my patio heater and stockpiling brown rice.

    However it is not true.

    It has been pointed out on here several times that the 97% statistic is based on only 79 climatologists polled out of many thousands, and that those participating were self-selected.

    Unfortunately BigWarming has a reputation for making statements which contain little truth. See AtlasGate as today's example

    The batteries are just one issue, so seeing as there are multiple threads running through this erm thread, I was wondering if the current Rocna steel specification would be less prone to brittle fracture at cold temperatures. I am in a dilemma over this.

    My aluminium fortress anchor is I suspect to ductile and as such should fail with very little degree of shank bending in cold conditions, not being particularly good at resisting fatigue cycles anyway.

    How will I survive cold anchoring conditions in this soon to be cold, cold, winter?
    Having time is unavoidable.

    So what is the consensus? Even if it were 50%, would you ignore it? If 50% of car mechanics said the brakes on your 4x4 were knackered, would you believe the other 50%? And risk a crash? No, you'd have your brakes fixed.

    Living with one eye on the environment and our effects on it - its not that hard really. And if in 50 years, it turns out we were all duped by 'bigwarming', hey at least we'll have a slightly greener planet, with slightly less pollution in it, and some slightly healthier seas (because weve positively turned away from oil and they havent destroyed alaska, and the arctic, etc etc .. ). Its a win - win.
