Subject: Carbon top mast for Laser Radial
Date Posted: 03 Mar 05 at 6:34pm

Anyone know what is going on, my wife sails a Radial but at 52kgs she is abit light in a breeze and I figure this will be good for her.

Will it use the same sail (I hope so as she's just brought a new one)!!!

What different properties does that carbon one have?

a friend of mine sailed at travemunde and after four races he had to quit, because his carbon top broke. the sail was totally destroyed and of course the top too. don´t know if it was something about his style of sailing (don´t think so to be honest). but you can use the normal sail, as i know.

Oh not too good. Though you do have breakages with the normal masts.

Allowing expensive options like carbon uppers represents a move away from the laser's trademark one-design concept.

The proposed carbon upper for the radial benifits:

1) More flexible
2) Better strength : weight ratio so less weight up top so less heeling moment.
3) More expensive: the builders can make mega profits by flogging an expensive upper to every radial racer worldwide. (Considering they charge millions for a simple aluminium tube, heaven knows what a carbon spar would cost...)
The lower mast would stay aluminium.
However, as well as all the cost disadvantages, the carbon upper would have another set back for the radial class:

The cost of buying a radial rig would increase from sail + lower to sail + lower + expensive upper. Decreasing the effectiveness of the "formula laser"

Good point but it would be a better mast for someone who is overpowered. will alow the top section to fall off slightly, but whether that is worth the costs.......

personally i like the boat as it is, and don't think it needs anymore alterations, tho i do have the XD power packs, tho this made a big differece for me
 i sail at 5feet 9inch / 1.75mts and
weigh 9st 10 / 62kgs

i struggle when the wind gets up, i symaphise with ricks wife

But will it work? Its no good having sloppy top section if the sail doesn't fit it properly. Downwind in a blow it could be  a bit unpredictable.

Also i thought that the point in having the 4.7 rig was that if you became over powered in a radial in a blow, you could switch over to the 4.7 rig  ..............isnt this carbon top mast going to contradict what they were trying to get going?

The idea was bought in around 2001. 4 masts were lent to RYA laser radial squad members I believe, and these were just used by these sailors... and the matter hasn't officially gone any further (that has been made public anyway). One of those got ran over by a car supposedly, so they should be 3... sounds like Jon Emmett has one. I think that they were made class legal in 2001 and you are allowed to use 'laser supplieded carbon top sections', however laser don't sell carbon top sections at the moment...

Sorry I do not have a carbon top mast, just an old bent ALU one like everyone else! The last regatta I did had carbon sections allowed in the SIs but no one had one. The testing is currently being done in OZ and I am sailing in Weymouth in the snow like everyone else. Basically a carbon mast would last longer and give better gust responce. For the record I weight 66KGs and am 5 1/2 foot tall, therefore I think a Bender mast would probably help my boat speed in most conditions...

the new carbon spar is going to be better for the lighter people that strugle in the light winds. the section is ment to have a longer competative life than the alu ones. i pensonaly have mixed feelings about the section but will defanetly be buying one.

Ok, well that was for a top of the line XD boat including trolley, trailer and covers, but even a 'classic' version is only 300 less, its silly money, for that money you can buy a one year old - almost anything else - which will have all the racing tweaks already.

Yeah, many of the parts are specialist tho.  As a result the manufactuer has a 'captive market' and can and does charge chatever they like.  The worst bit is that laser moved most of their building to eastern europe to reduce costs and a new boat is still more, its a rip off, pure and simple

Hi, I have been involved in the development of Carbon Spars for the Laser Including the Radial, The site will have more information as time goes on www.cspar.eu  I have personally sailed with the Standard carbon full rig and really really enjoyed it, there is a positive difference. We do have a Radial rig as well but at the moment the only three in the country are at our store. Im going to Hayling Island UK in February to present the Laser carbon Spars there, your'e welcome to come along. 

I will be loaning a Carbon Radial rig with the Hayling Island Junior Laser squad to get feedback, all feedback will be posted on our Blog.

The spar dimensions are identical to the Aluminium spars so everything fits (to answer a previous post)

Any questions ref Carbon for Laser please drop me a line. I know at present they're not class legal but surely they will be one day..Smile

Best

It may well be that a carbon spar will be legal for racing some day, although I doubt it will be before the various Laser builders and rights owners finish kicking each others ankles in the law courts, but we can be pretty certain that these ones never will be...

And isn't the whole idea of Laser sailing that there isn't a positive difference between boats?

Manna from heaven; Carbon spars for Lasers, EXCELLENT, I'd have them if I still had one. Gotta be better and cheaper than wrecking a sail every season or less if you are really trying with enough cunningham to bend a 2 inch scaffolding pole.

Class legal, who cares, it's a beach boat that's been shoe horned into being a racing boat anyway.

Transformed the Byte; ask Mr Tick.

I was getting to that......Why stop at carbon mast? If you are going to make it illegal then go the whole hog and give it a modern rig?

I fully appreciate that in a 'level playing field racing situation' any advantage over another boat in the same race because of 'advanced equipment' that increases speed (including Carbon spars) isn't right or fair.

The very point of "fairness" leads me into an interesting fact. At C-Spar EU and  C-Spar NZ we realised as developers of carbon spars that prior to becoming class legal there would be a keen interest from many sailors from the less competitive arena and we would never expect 'yet" to see our spars in any race.   

For the Laser racer we developed a "Race training" spar----- we decided to focus on a completely separate item and came up with with a composite top mast section, mainly to help reduce costly and untimely top section replacements. Our aim was to develop a top section that was the SAME weight and the SAME bend as the present class legal Aluminium top section. 

We tested 6 different 'class legal' Laser performance supplied Aluminium tops for both weight and bend and none were the same (in-fact the margin of difference was astounding) weight +/- max 12% and bend @ 12Kg on tip was +/- 22% 

This means that IMHO there have been Class Legal races where potentialy the wrong boat has won (i.e. on the grounds of an equipment advantage) not all competitors could possibly have benefited from say that +20% Top Mast bend when conditions were just right?

At least with Carbon/Composite Spars the tolerances of difference during manufacture are +/- 1-2% on bend and on a very similar figure on weight, compared to aluminium that is obviously considerably higher.

Class legal Aluminium offers a level playing field? from my work so far I think this unfortunately cannot be the case.

Whatever you do don't start looking at critical hull measurements.   You need to pick your hull very carefully as well as your spars.

For the olympics and worlds the boats are supplied anyway though, so while it may be beneficial in getting you there, you'd better be able to make any old dog go fast if you want to win a title...

That said, I measured 4 supplied boats for the worlds in 2011 and they had identical measurements.  Not sure if they make sure the spars match as well though, less likely I'd think.

*If* my understanding of the manufacturing problems of alloy masts is correct then a whole batch of spars made at the same time will be very close. My understanding is that the dies used to create the extruded section wear, so as they get older the wall thickness gradually increases until it goes out of spec, then they have to start again with a new set of dies.

Personally I think that it’s only a matter of time before carbon sits alongside aluminium.

If a carbon boom is available for the Laser/Kirby torch, with such a one design class what’s to stop the manufacture and purchase of carbon spars in other classes?

RS 100, 300, 600, 700, are already specified in carbon, RS 300 is going to get a carbon boom, Byte has gone carbon, in fact below is a list of spars available in carbon.

Selden Carbon Spars

Can anyone remind me of a new boat recently launched with aluminium spars?

I am aware of several discussions where VERY traditional classes are considering “playing with carbon” to see how it goes. 

I know this puts them out of class but where they sail in handicap fleets and are unlikely to travel, a more enjoyable sail seems to be more of a priority.

Sorry if this is heresy, I just think the idea is out there more than people realise.

For three Classes that are in my awareness, Osprey, Phantom and Contender the option of a carbon rig seems to have done them no harm at all in terms of popularity.
I think the general opinion for at least the Osprey is that a carbon rig is little faster in terms of outright speed in a straight line drag race. However it seems to offer a kinder and more pleasant sailing experience especially for lighter teams, of course this could or should ultimately result in a quicker time around the course. 
Is the cost of carbon vs aluminium determined by manufacturing costs or the market forces of supply & demand and desirability.

I did hear that China's need for financial growth, resulting in a rate of 10% was about to slow down as they service their domestic market. China has been sucking in raw materials keeping World commodity prices high. Could aluminium become cheaper making carbon an expensive option the way it used to be?

Carbon fibre is aesthetically pleasing to the contemporary eye, but will that last? 

Dishwashers used to be an expensive luxury item so you put in pride of place in the kitchen because you wanted it to be seen. Then they became commonplace and were covered up (integrated) but just showing the control panel, so people new. Eventually they were obscured completely with the controls in the door thickness, because everyone had a dishwasher no one cared.

A friend of mine has a Phantom with a WHITE carbon mast. I await seeing a carbon mast finished in silver.

Cost, availability and fashion must all play important parts but is it not easier to engineer different characteristics into carbon?

Sailing costs coming down !!! Now there is a truly radical concept, not sure that is going to happen even if Ali does flood back onto the market.
I think you will find the thinking behind a white carbon mast is related to UV protection and heat absorption, though thinking about it silver would do that equally well.

I believe the price of aluminium products is heavily tied to energy costs, so I don't see it becoming cheaper any time soon.

I first saw a silver painted carbon mast about ten years ago.

Clear coating carbon masts isn't really a very sensible idea. I reckon that, whatever people may say about UV resistance in clear coatings, that its not that effective because the clear coat peels off after a few years and paint doesn't seem to, so I think that most likely means that enough UV is getting through to degrade the varnish/epoxy bond.

......


Carbon is a great material, but clear coated carbon is hardly the latest thing in fashion.
I have a 1992 motorbike with clear coated carbon mudguards. It was the latest thing 20 odd years ago.
The price of an ali mast is not really about the commodity cost of the metal, that is about £1200 a tonne. So even an RS400 mast only has about £12 of ali in it.
The commodity cost in carbon is below £200? in carbon tow and resin.
The cost is in manufacture, and the key to that is quantity.
