Is anyone here trying to stifle development? I think not. What some of us object to is the stream of contempt and insults flung at current designers, manufacturers, sailors and classes.
Grumpf, do you have any evidence whatsoever for your claim that dinghy designers are behind in their approach to technology? Why in the world is "hollow carbon and bamboo technology" any better than the hollow pre-preg (or in-house impregnated) carbon and Nomex technology that dinghy creators have been using for decades? Probably the vast majority of the world's best dinghy designers have been creating carbon/nomex boats (i.e. those using the technology of the space shuttle, spacesuits, F1 cars, Airbuses and Dreamliners) for many years. Some dinghy builders have also been involved in America's Cup challenges that spend hundreds of millions on design and technology. Come on, do you really think that the creators of the AC boats are too damn stupid to spend their hundreds of millions on leading-edge tech, and do you really think that none of that has passed to dinghies? We know that is simply not the case, because there have been carbon prepreg/Nomex dinghies (for example) around for many years. There were carbon dinghies before there were carbon F1 cars - that's a fact! Looking at a comparable sport that you brought up, the leading-edge Cervelo bike brand has recently fitted a bike with load gauges to work out stresses - gee, that was done by boats in 1987.... Most of your posts contain uninformed and abusive opinion. Many of us here would have known some dinghy designers and builders and many sailors for years. You are abusing them continually by your comments. Some of us find that your continued stream of abuse of people we like and respect, behind their backs, to be quite offensive. PS - as far as encouraging innovation, yes it's a great thing. However, these days it seems that innovation is mainly promoted by abuse of current boats, which seems endemic. I'm no marketing expert, but as I understand it negative marketing is a no no, which could be one reason why there is something of a lull in development. Edited by Chris 249 - 06 Jun 12 at 12:21pm |

Foiling was innovative - back in 1980 when James Grogono pioneered it at Weymouth speed week along with the guy stacking kites, jacobs ladder.
As to me wishing there would be hundreds of these things, that's poppycock, if this had been a serious commercial venture, do you think I would have shared it, honest and open the way I have to date? It was never going to be anything other than what it is from word go. If I'd wanted commercial it would have to have been something of the Project X ilk and at that price level in this current market. This thing's main unique feature and the feature everyone initially debunked because of the worries of foils without end plates, was the tunnel hull, and we still don't know if it would have been better or worse with a solid hull, or the gap wider, the fact it goes at all was a (pleasant) surprise. What let it down was the build, the build time, the build weight and the costs that accrued beyond my expectation, then even in my madness I wasn't going to spec a left field idea like this with full carbon nomex, all though I did ask for bamboo, it isn't available over here at this or that time. It's all very well Chris 249 going on about the great tech there is about, er just give me the name of the class of dinghy that has adopted it and I'll go right out and buy one, back handedly he has already made my point. The stuff is around and the UK in other sectors is way head of the field in say F1 or aero space, but all the time the classes have their luddites and the market performs the way it does why would anyone in their right mind risk building super light, you only have to go back a few pages and we needn't revisit, but it comes round to the same thing, wanting super light or high end isn't in the culture. That is reserved only for Americas Cup attempts and the like. Whereas other sports do want hi tech and as there is a bigger demand prices of the higher performance stuff inevitably drop, so dinghy designers are hamstrung by that culture and of course I recognise there are excellent examples of new stuff one only has to look at the Aura, but where is that going now? So who's to blame? Dinghy Sailing culture is to blame and that I shall continue to torment as long as I draw breath, or it changes which is extremely unlikely anytime soon and i shall continue to mess and meddle whilst bantering that evryone else is crap but me, which of course I totally believe..

The answer to that question is because it's greener and the resin they are using you could almost wash your hands with. I probably don't have to tell you of the qualities of bamboo as a fast renewable or it's tensile strength or weight to strength being not far off carbon. Or it's price competitiveness. So I would have thought it's a perfect recipe for the dinghy world to adopt, it's kind of wood, it's cheap and light, yet try and find me someone over here using it to build boats with...

I am surprised by your continued praise for the Aura, with which I agree ... when I spoke to the builder at the Dinghy Show he described it a a Musto Skiff for two lightweights, very similar under water shape he said ...

So which sports do want high tech as you claim? Surfing? Hell no. Cycling? No higher tech than sailing - UCI bikes have very stringent restrictions. Downhill bikes may be different, but the very fact that you have held such overweight creatures as examples of "development" is proof that light weight isn't everything.
Car racing? F1 is high tech iin some ways, extremely restricted in others (for example, it has a weight limit, so I assume they are also luddites to you) but that is a tiny sector of the sport, and the sport is incredibly tiny considering the vast size of its parent industry and the number of people who drive. Kayaking and canoeing? You'd have to be kidding, it's the poly boats that are selling and even Olympic kit has weight limits. Snow sports? I honestly have no idea, but we are talking about simple pieces of kit smaller than a centreboard or boom, so price is obviously going to be less of an issue.
For all the abuse you throw around, you have still not actually made a factual basis for your claims. You have not showed us a comparable sport that is healthy in numbers and has no weight limits or faster development (demonstrated, not commercially hyped baubles that could have hurt the market) or higher technology in common use in equipment of similar. Yes, the technology exists to make lighter dinghies. It has been adopted in Moths, 12s, Rs, 18s, As, etc. The market knows about it very well, it's just that the market also knows that spending thousands just so you get to either do less sailing (around the same length course) or more laps (if they make the course longer) is not normally worth it, since pure speed is not what makes most people go sailing. Oh, and if you want to move a boat around easily, investing more money in a good trolley is the best way - that makes up for about 80kg extra boat at least, in my experience. High tech boats cost up to $20k for a 12' bare hull - and before you sl*g off friends of mine who build such boats, that still makes it much cheaper, size for size and pound for pound, than the high tech products in another sport such as cycling. By the way, not everyone totally debunked a foil without end plates. Some knew - and posted here- that such foils had been used in the past without major problems. If you stopped insisting that you were sent from heaven to shine the light of your vastly superior intellect on the moron peasants, you may have actually known that. In some ways I am coming from an outsider's angle too, because UK boats are heavier than the ones I am accustomed to. I find some of their construction slightly odd (i.e. very thick thwarts) but you can't have it both ways - if you want them to be vastly lighter, you have to stop doing daft things like throwing high-tech sports equipment onto rocks. The fact is that the species has evolved to fit its territory and it has done so very well. Edited by Chris 249 - 06 Jun 12 at 2:09pm |

Give us facts to show that it is greener to take diesel and petrol to power machinery to drive loads of bamboo into a factory powered by coal-fired electricity, where it is processed and driven by diesel truck to a diesel ship manufactured from thousands of tons of metals (mined in an energy-intensive way) and then drive it across the world to a dock where a crane driven by fossil fuels will load it into a truck driven by fossil fuels to a factory where it will be combined with chemicals derived from fossil fuels and then also refined and transported across the world and then put into small plastic containers and then used to build a boat.... compared to just enjoying and relishing the sailing to be had with craft we already have. The vast waste in taking non-degradable plastic boats and chucking them into land fill is surely one of the reasons that we shouldn't be sl*gging off existing classes, instead of enjoying them. The waste involved is horrific - everyone seems to complain about boats mouldering in dinghy parks or taking up scarce mooring space but surely one way to get around it is to stop telling people they shouldn't be using such older boats! Imagine how many more people could be gainfully employed in the boating industry if more of the cash was being used to renovate old craft, rather than throw new ones together on a production line that churns up priceless non-renewable resources. Yes, under current economics it's not viable, but neither are your fantasies. And re-using old boats to save materials is probably a lot more innovative, as a vision, than just more calls to destroy more of the boats on which our sport is built. Yes, bamboo's tensile strength is impressive but then again kevlar's tensile strength is very high and it's largely been abandoned in boatbuilding. I've got no engineering knowledge but as I understand it, bamboo has major problems in variability and flex strength. Comparison of tensile strength with carbon is not necessarily valuable as carbon has fairly moderate tensile strength (lower than even E glass AFAIK) but it is valuable because of its compressive strength etc, which is a problem with bamboo. So we are back to the issue that you are giving out abuse, not facts. Yes, on the one hand bamboo could perhaps be a great material but (1) whether it will create the ultralight craft you are demanding is completely unproven, and SUPs are not much of a test bed; (2) racing dinghies were there 90 years ago (as proven by documented history) and the facts show that they have since been up with all other comparable sports in high tech construction and we are back once more to the fact that yo are throwing around insults without facts.

Abuse given to Australians is legal - fact.
At no time is an Englishman expected to back any comment he may have made to an Australian, the Australian should simply accept the wiser and superior words of the Englishman and be humble, in fact be happy he is even being acknowledged as anything other than a convicted felon or a bush dwelling aborigine. This is the Law. So now to the facts. The factory I recently visited sits adjacent to the Bonneville Hydro electric plant on the Columbia river the electricity is free. The resin I told you of's formula is secret it is being kept in the US to protect their intellectual property from thieving Chinese (and Australians). The wood used in blank construction as well as Bamboo is from managed forests from within a 50 mile radius. The Sports that like light stuff as well as Windsurfing, which no longer has the sun filled uplands of a better tomorrow in which to bask in the fires of progressive innovation, are SUP ( a hollow race board), kite twintip and surf boards and wake boards capable of being both light yet capable of sustaining punishment in cable parks. I've no doubt that somewhere along the Gorge folk are using similar stuff to build sailboats and all manner of stuff, but those are the instances that have prompted my latests rants. You may now go to your room and reconsider your position.

So to recap:
The V Twin did not live up to the lofty claims of it's designer. This is the fault of someone other than the designer. The project manager also seems to have been betrayed by incompetents. One has to conclude that the successful completion of development projects is harder than it looks. Maybe that's a clue. Even the blind squirrels occasionally find a nut. SHC |
