But if weight is so important, what are you doing messing about with a dual suspension bike that is heavier than a hardtail, road bike, singlespeed, hardtail or CX bike of equivalent quality?

I'm not expert, but as I understand it and as Bike Radar puts it, "interest in road cycling in general and in hybrid bikes in particular is on the up, mountain biking’s star is on the wane, and the level of interest in folding and singlespeed machines remains static." My books on bike design indicates that the mountain bike marked started to slump within a year or two of dual suspension and discs hitting the mass market. So where is the proof that the increase in MTB technology has actually made it more popular?

Sorry, but a piece of comparatively heavy sporting equipment of declining popularity doesn't seem to be an example to hold up when you are saying that boats must lose weight.

And is there any evidence that MTBs are actually advancing faster than boats? Bikes have auto suspension, boats have flex-tip masts. Bikes can adjust their forks, boats have single-string rake, ball bearing travellers and gnavs. Bikes are hydroformed alloy and carbon, boats are foam sandwich and carbon. The ultimate performance dinghy (Moth) has increased its speed vastly more the last decade, and the downhilling speed record has been static through that time while road speeds have actually declined, to the great relief of those who see it as evidence of success in the doping fight. So there's not much evidence that bikes lead boats in development or that greater speed equals greater interest. 

BTW re Austin 7s; yes, people no longer drive them around much, but on the other hand the '50s vintage Lotus/Caterham 7 still claims to be the world's most popular racing car. Nor does any popular motor racing class seem to be without the minimum weight rules you are so much against. So it's not just the sailing world but also the motor racing and bicycle racing worlds who are all marching out of step, and only you who is right.....

I completely agree that dinghies need to be more accessible, but you can't make them more accessible by demanding that they become lighter (which means extra expense or reduced durability or a change in attitudes, like not crashing them onto shingle beaches) AND cheaper AND AND easier to sail AND more complex. 

One thing that no one in the "destroy all the old classes" camp has ever demonstrated is exactly how this would work. For example, if the Solo started to decline tomorrow, the existing owners would suffer a considerable loss in their resale. Exactly how are they going to then afford to buy the new craft that those who claim superior intellect and wisdom tell them that they need? And don't forget, despite various subsidies the classes that take the ultra-light path you are advocating are failures in the mass market. 

There are physical issues in design that complaining will not erase. Surely the hybrid windsurfers like the Mistral Prodigy you were involved in demonstrated that! For all the hype, they failed dismally at competing with longer boards because the laws of physics do not change, no matter how many Prodigys or VTwins are launched.

What you seem to be doing is complaining without worrying about reality for normal sailors, just like people complained about longboard windsurfers back in the '80s - and look how much that hurt windsurfing. The basic idea that sport equipment needs increased performance and reduced weight is simply not borne out, as looking at comparable sports demonstrates. Dinghy sailing is progressing quickly, compared to many other sports (although IMHO there's far too much emphasis on increased performance and not enough on increased accessibility) but the fact is that the fastest boats do not attract many sailors, whether noobs or vets.

Hw come? A keelboat is a thing with balast on the bottom whereas a dinghy is bodyswung? Javelin is actually not that heavy but it is strong.

The Javelin at 17'7" is very fast upwind in those conditions. The ok coped well with the gusts and then had a knack of floating on its side with the mast horizontal to the water. The quite wide hull then shielded the sail from the wind, a little wriggle from the helm and up it came again. That OK never went over properly all day. Someone did try an 800 but that broke and came back as did a 400. The two best boats on that day were 'ancient designs', but they were the best.

I would like to meet the man who could build a light boat that could cope with that.

Ultimately, that is the ugly logic that leads us to keelboats.

People have known about carbon for ages - well before the trials. IIRC from the dinghy show, Rodney P was playing with carbon and honeycomb in his FDs. Wikipedia tells us that honeycomb sandwich construction was proposed in 1915. Tecnara built Tag Heuer in 1992, just to prove that the boatshop floor isn't a labatory... Smile

Downside of carbon is the cost.

Sorry, please feel free to remove my posts then! Confused

why are you all so obsessed about the weight of the contender?  It's a bit like constantly asking 'does my bum look big in this?'

the answer is usually yes, but who gives a damn?

Well, I am - not about my bum or yours, but about the weight of the Contender on the beach - so much so that I'm pondering spending a stupid amount of money on one of these:



I did suggest that we should install an aerial line that could lift boats straight out of the water and up the beach, but no one took me seriously, can't think why. Disapprove

I imagine that also.  I also imagine that if had been a desirable thing to do, then they would have done it when they changed the sails and mast- both for the mens in the new rig and for the women's in the FX rig. 

I also imagine as a boat specifically designed for Olympic grade sailing, where the cost of the equipment at the sharper end is really small fry in total campaign terms, they do not have the same commercial considerations as someone lipsticking an old design with 500 active customers to keep happy.

It is precisely because they have chosen not to reduce the weight that I imagine weight reduction wouldn't actually be desirable to the boat's sailing characteristics in this specific high performance boat.  Unlike some other forum folk, I tend to think the various stakeholders in the 49er class tend to know what they're doing, and certainly know what they want.

Nessa, i love the contender! I am even looking for a really cheap (and heavier still) one for big wind fun, should the D-one not be available.  As a boat though i think it could afford to lose a little (but then so could i) Wink
