    Bi plane rigged wing mast cat pros and cons?

    Were some of his numbers wrong?

    wtf Australia what is yall doing??

    Yes, 97%, I was using shorthand. If you write off that degree of consensus as alarmist you should stop all medical care and start smoking 50 a day. I've read it and understand it. I don't read facebook. You are plainly the opposite and your "facts" are discredited conspiracy theories. You should get your scientific wife to read the full ipcc works and explain them to you. Maybe also show her your history of posting on this site. She might find you as insightful and hilarious as you and maybe four other lonely sad men do.

    I'm not sure even you know what point you are making, but consider that the biggest consensus of scientists on earth on any issue ever, having undertaken the biggest scientific study of any issue ever, all think you are wrong. I guess there's a chance they are wrong and you and and LB (who parrots a discredited conspiracy theory about the Greens being to blame) are right. Sort of funny that you two think you're the ones who aren't following fake news though.

    On your logic suggesting listening to your oncologist is alarmist. I've read the IPCC reports. If you have you haven't understood what it means. But if writing off the entire scientific community as 'alarmist' is the way you want to deal with Australia's heat and rainfall outlook then you're obviously not interested in facts and should stick to your sad internet posturing. Very brave and pioneering stuff.

    These fires arent a culmination, they are the beginning. If your solution to Australia's looming environmental and climate crises is to hate the greens and obsess about hazard reduction burning while ignoring emissions, then you don't understand the science. Or maybe you do but have vested interests.

    Big coal will cause far more casualties. Are you wanting them charged too?

    What's the construction? And can you say what a 'reasonable price' might be?

    What's the story with Crowded House? It's for sale?
  10. Yes, I can see flooding working, although not quickly if on the hard like Mala. As much improved as they are, lithiums are still a greater fire risk than lead batteries and fire at sea is bad. On an otherwise unsinkable multi it's the worst. I'd gladly destroy/abandon batteries that otherwise risked burning uncontrollably. Not being able to start the engine is small beer by comparison.
  11. Maybe. But your comparisons are off. Weight and complexity compared to what? Extinguishing and flooding systems as above? And as for not starting engines afterwards, a fire will likely be the end of the burning bank either way. Lithiums are relatively light so low siting less important. And their highest loads probably are as near the bridge deck as anywhere (capstan, winches). If boats had the same maintenance budget and regime as commercial jets then that comparison might make sense, but they don't. Given the loss on Mala, and that another poster is planning an actual flooding mechanism, the idea of a disconnection and dump doesn't seem much more costly or complex. But whatever, if you like this sort of boat you're right on top of avoiding complexity and cost.
  12. On a cat lithium batteries could be in a box that can be jettisoned in a fire rather than low and flooded inside.

    Agreed, although most boats aren't faced with it ever because they don't claim to and can't go that fast. In this context, the 20 knots is invoked as an illustration of what it means by those who say boards would not break. Here, the better question is probably at what speed the boards, drives and rudders will break. If that's below a scary speed, then impact injuries are no issue. If it's within realistic cruising speeds ranges, then for anybody who does want to cruise far and wide it's worth thinking about. when far from help, exposed foils like that are not that smart imho. All probably not an issue for GB owners because they're unlikely to be really cruising and have bought the boat for showing off. Like their maserati, unreliability, high repair bills and depreciation are acceptable downsides of looking like the guy in the ad.

    Yes, although more complex for more highly loaded gb ones. plus you need to get the builder the design files (easier if original builder solvent). then get to airport, somehow install if no hoist etc. Kickup boards are a bigger compromise and harder, but kickup rudders have been successfully executed on a range of fast cruising tris and cats. There's not much performance compromise and relatively speaking not that much expense for the most important moving part on a boat.
