Nnoooooooooo, there must have been a shift in the time-space continuum. The universe will collapse and we'll all swirl out of control down a wormhole.

Interesting that this is apparently coming from ILCA rather than whoever makes lasers this week.
Not sure that composites really have the same dynamic bend characteristics as cheap alloy poles.
How much?
Can I buy a replica one yet?
Huge potential for replica topmasts to have different characteristics.

If the ILCA was really driving this instead of the builders, they could have put a much better rig on the boat at sensible cost.

Funny old game, but good if you don't take it too seriously.

Or into a crack at the bottom of the mast pot perhaps?

I've said before on here that the top Laser sailors buy a new rig every couple of weeks and a new hull every year.... ok I didn't really say that but to stay competitive at the top level you need new kit more frequently than many other classes due to the primitive construction (it was designed as a beach boat after all). A 'L@ser Plus' with a a carbon/kevlar rig (which would be a different class, like Radial and 4.7 but nicer to sail and with fewer compromises) and an FRP/Vinylester/Epoxy hull, weighing the same as the standard but having a much longer competitive life would rejuvenate the class to a huge extent. Then allow some flexibility on layout to allow us short RS-es to sail one comfortably and you have, possibly, the best of both worlds. Byte has done the 'proper rig' thing, Blazes have gone Epoxy and added a carbon mast option without outclassing the older boats (BTW is it just me or is the original red/white Blaze hull the prettiest) both without stepping too far from the one design philosophy...... Oh well, it'll not happen in my lifetime I guess but no matter, a few years Blaze sailing and then a Solo beckons Embarrassed

Hard to look at sales figures and conclude they've got it right and the Laser got it wrong though.

I know everyone here seems to sl*g off the laser but the vast majority of owners that I know like the boat. They like the simplicity, the fact that it's reasonably cheap and everyone virtually has the same equipment. The only thing they don't like is the main sheet catching but that's about it. Probably the reasons why over 200000 boats have been sold.

Exactly so.
For £2k outlay and say £400 a year in sails and/or depreciation, it delivers.
But for something of its size, weight and simplicity, the amount of stuff that fails is unnecessary.
And these days the hull could be made to last a very long time without weighing any more.

That may not be altogether a good thing. As has been found out by a number of the high end classes, the result of having everlasting hulls is that you have no secondhand boats available, very few new ones being built, and little possibility of class growth.

I've come to the conclusion that there must be an optimum rate of obsolescence for any class. If they depreciate too fast no-one wants to buy one and the class dies, but if they depreciate too slowly no-one wants to sell one and the class can't grow.

In defense of the boat and the international association.
Although it seems painfully slow coming, massive improvements have been made to the boat over the years.
I wait with interest to see if the composite mast will have a tighter spec. than the ally and end up being no more expensive.

Laser, with their 'superior' strategy, have lost more potential sales in recent years than most classes have ever sold in the first place !  (I don't think most other classes are even on their radar either frankly).  Surely that is the real elephant in the room. 

A chunk of that may well be down to the 'messages' they have given out to the world via legal disputes etc in the last decade or so.  Maybe some of that was unavoidable.  Another part is as a result of holding 'true' to the product concept that is now arguably decades beyond its sell by date .... Extending the product line forward will not happen without some specification change to the product offering - but it just all looks a bit 'too little' and almost 'too late'.  

There is no doubt 'Laser' actually think some changes are needed - they have already undermined the 'totally unchanging' concept themselves. (The 'composite' mast being just the latest mod of several in recent years).   But will the market lap it up or just nod out of passing interest and move on ...?.  

The question I would ask - would you today as a hypothetical supplier rather be building up Aero sales or attempting to limit the decline of Laser's 'historical' position.   They are opposite ends of their product life-cycles.   I'm betting 'Laser' are still well ahead on unit sales and overall margin - at the moment ... but there is more and more writing on the walls.   I'd be looking over my shoulder.

Get ready for a whole new level of cheating as masts are sanded down, built up or swapped for lighter replica ones with different bend characteristics.

Maybe people will just appreciate the top mast not bending or breaking so often?
So long as the Laser has olympic status, there is no threat from anything else.

So what - it's a meaningless comparison? They also sold far more than nearly any other class. Of course a class of that size is going to have lots of potential customers who go elsewhere, but you can only tell if the strategy is a good one or not by looking at the whole picture.

Which ever way you cut it, as I said on facebook, you're all being conned by that ludicrous price, if it is as rumoured in excess of £500 which in the windsurfing race market which is arguably a lower volume arena, a full carbon full length 570 two piece mast with a couple of margins in it retails for less. Then again a performance mast suitable for a beach toy such as the support of the top section of a 7 metre sail with minimal luff curve, can be half that and with two margins, where Laser only has the one.

Y'all are about to be ripped off, so good luck to the replica market I say, who's going to tell under that luff sleeve?

I am inclined to be iGRF "light" on this one.

Laser: brilliant fun my second boat and it taught me loads about boat handling especially as I was then sailing on the sea out of a very tight and fast running harbour mouth. I think it cost me £300 in the 90s for a 47k number. Bit of glass around the mast pot through a 6" hatch and job was a good un, replica sail after a year or two and I was cooking. Given the rep sail I suppose any question of the repair hatch and another one next to the CB slot with a bag for spare string, hat and Mars bar putting it out of class is irrelevant.

Really though, I never aspired to a new one, for the (to my mind) basics construction materials, nothing special fit out and well reported failures the new price seemed insane.

That's my love hate relationship with Lasers. Fantastic sailing experience with the boat but a fun boat that takes itself too seriously and costs too much.

£500 would be taking the mick.
But I suppose they'll stop making the ali ones and Noble will have to cough up?

By the way who mentioned carbon?
Composite probably means grp.

Maybe it'll be like the early 'composite' bowsprits on 400's, suddenly a rush on used metal ones.....

£500 is the rumoured price from those in the know. the Aussies are flogging it at $850 (AUD) so near 3x that of the ali section.

Carbon masts can be repaired
Metal ones are scrapped.
Personally I've not found ali masts to be the key to cheap premiums.

Alloy top section is not far above my excess.
Yer actual bare tube, anodised any colour you like, is cheaper than a rake of ales and a good curry.

Laser have mostly got it right, apart from a few times when it's gone pear shaped but mostly not down to the Laser 1. 

I happen to know that because of the huge volumes of parts they are buying they get them very cheap. The example I was given was a toe strap, they were paying pennies for them, literally pennies. I can't remember the exact figure but it was something like 64p a unit. They retail for something in the region of £50, without looking. Some people look at that and say "how dare they!?" but most see the complete boat price and think "seems reasonable" and pay out. 

It's all very good poking fun at it but in reality you can't buy it cheaper, so in most cases you're better off just sucking it up and buying it. Most of us are sitting here moaning about stuff like this but working for companies that do at least try and make a profit. That's all they are doing is making a business work and if that means selling a mast for more than we might like to pay for it then good for them, so long as it isn't so expensive that people refuse to. The right price for any given part or boat is as much as you can possibly get away with, from a business point of view. If that means you don't make a profit then it's probably that its a bad product or your sales team need a good kicking, if it makes huge profits then who are we to complain, we bought it!

Where is the evidence for that?  You must have done an analysis or else you wouldn't be stating this as fact, so could you give us more information?  Have Laser sales declined more sharply than other classes because of their strict OD rules? 



There is no doubt 'Laser' actually think some changes are needed - they have already undermined the 'totally unchanging' concept themselves. (The 'composite' mast being just the latest mod of several in recent years).   But will the market lap it up or just nod out of passing interest and move on ...?.   

Since when did they have a "totally unchanging" concept? The first major changes occurred something like 1 year after initial launch, if I recall correctly. The timber foils were replaced not too much later, then the sail was replaced....this was all by the '80s. 

There does not seem to have been any "totally unchanging concept".

The question I would ask - would you today as a hypothetical supplier rather be building up Aero sales or attempting to limit the decline of Laser's 'historical' position.   They are opposite ends of their product life-cycles.   I'm betting 'Laser' are still well ahead on unit sales and overall margin - at the moment ... but there is more and more writing on the walls.   I'd be looking over my shoulder.
The whole sport should be looking over its shoulder, because if one of the most important classes in the world is damaged by those who carp about it then the whole sport will be seriously harmed.

The Laser has GAINED market share compared to most of the classes that were around when it was at its peak. The Laser is not the problem with dinghy sailing - it's the other classes that have suffered the big drop in numbers. Why attack one of the few long term success stories?

There are also a lot of fables about Laser kit. My brother was top 25 in the open standard worlds, for example, and he had one old borrowed sail and one new sail in his entire Laser career. We've had people say that Tom Slingsby, for example, would go into the factory and weigh dozens of masts before selecting them. Tom (who I knew as a sub-junior) has told me to my face that's not true, and that he is not allowed in the factory. My former PhD supervisor was the chief scientist at the Australian Institute of Sport and in charge of the study of the bend characteristics of Laser masts, and he says that the study revealed no surprise at all. Stiffness is proportional to spar weight and the differences (in our sticks, anyway) is negligible. Krystal Weir, former world champ and another of our Olympic Laser reps, didn't have that many sails and like Tom or Michael Blackburn (world standard and Radial champ and Olympic medallist), she was not very gear conscious. Both Tom and Krystal have the attitude that it's silly to need special gear when you have to use supplied kit for the major regatta. Learning to adapt to the minor gear differences you may meet is a skill that is needed for success.

The Laser as launched was developed quite a long way from the initial beach boat concept, by the way. At the time there were several vast multi-national conglomerates operating in the beach boat market in the USA, including some of the world's biggest companies. The Laser was developed into a serious but simple racing boat before the product was launched, because the backers did not have the cash to take on car and missile manufacturers in the beachboat market.

Chris, while you are correct that many of the top sailors won't be selecting gear, there are also documented examples of those who will measure mast rake, weigh topmasts, etc. But the vast majority of Laser sailors aren't in either camp, or even doing local open meetings. They are sailing in their club handicap fleet on a Sunday and on a Wednesday night. Some won't even be aware that the Laser is an Olympic class, let alone that a plastic topmast is now allowed. Be interesting to see the reaction at clubs when the first ones filter down to our level.

Paul Elvstrom was renowned for the hull finish on his own boats, it was usually terrible! He reckoned that a couple of days polishing the bottom was equivalent to one missed wind shift so went sailing instead. 

The top laser guys don't need to buys new sail every year 'cos, as Chris points out, they get one supplied at every regatta Ermm

I don't think the Laser is a bad boat, but neither is it a great boat. It has a number of shortcomings that make it quite unpleasant for me to sail (I have owned one and sailed several over the years) so I bought something else. It has been demonstrated that when a true one design allows improvements to hull construction and layout (Enterprise and Blaze are the two I have a particular interest in) without reducing weight or changing the hull shape, the new hulls, which may be nicer to sail, are not faster than a well maintained older boat. Laser could make the hulls more durable and introduce a deck layout that was 'shortaRSe friendly (something like a bigger Byte maybe) without making those boats faster than a Standard. They could also introduce a new rig (which probably would make the boat faster but would be a different class in the way that Radial is) which might rejuvenate the boats appeal to younger sailors as well as making it pleasanter to sail. I can't see how that would be bad for the class or the manufacturer, or the sailing public.......

I have no problem with Laser (or any other class) updating periodically. Lasers issue seems to be the slightly haphazard manner in which it happens. the composite mast has been in the pipeline for years and years, but then gets introduced with just a few months notice. Meanwhile, in the US, you can't eve get a new sail.
If the ILCA, rights owners and builders published a 10-15 year plan it would provide some assurance and certainty as to the future of the class. Who would buy a new Laser today not knowing what the future holds?

I don't think many people buy a new laser with a view to the next 15 years, most are looking at being competitive for the next 3 years or so. And most will probably we trading up from an older laser.

Anyway club bar drivel suggests the new sail needs so much mast bend to get the fullness away from the mast, so a slightly bendier top mast would be better. In some light conditions it did seem to me that replica new-style sails were stalled in the top half where my legal old-style sail could be allowed to twist off a little.
I've not looked at any gen-u-wine new style sails yet.

I suspect the new pole will be a must have for the serious laserists, like the shiny new grp foils.

The stuff coming out the class/builder categorically states that the new top section has the same bend characteristics as the current section.... (just like the new sail trims identically to the old sail.....Wink)

oh come on, be serious. Apart from anything else it would be rather easily spotted. An all glass spar of the requisite weight would be bendier than the alloy one, an all carbon one stiffer, so a mix of the two should deliver, although I imagine it was rather tricky to get the exact balance right. With that and an epoxy based layup there should be the potential for a much longer lived spar, especially if there's no rivet.

A more interesting question is whether there's another link in the chain that will be the next to be exposed as not strong enough and start failing under the vastly greater rig loads the modern Laser has inflicted on it. One change leaves a toothing stone for the next, as an interesting Italian political commentator rightly said... To my mind, as I've often said, it all went wrong when the Laser association failed to ban all those stupid knots and eyes and things. The rest has followed from there.

Been a weak point for a number of years. Most insurers won't cover mast pot failures on boats older than 100,000 (might even be higher than that now).

Time will tell, pots usually rip out before a top section goes if they are going to go and usually as a result of poor boat maintenance.

they have never said that for sails  , except   the right is reserved  to decide that a repaired sail is substantially modified ... 

a few sailmakers dow n the years have done a good trade in buying  the scrap sails  from insurers and  repairing those  which are  easily repaired without a great deal of replacement material...

I'm not sure if I believe it, but I've heard the opinion that the problem with top masts is actually modern aluminium (or is it aluminum?) is stiffer than when the Laser was conceived.
Specs of materials creep over time.
I have put put a bt of bend in my mast. Wasn't there when I bought it! The most stress it has seen is probably stuffing the boat into the back of a wave, I haven't even capsized yet!, and I don't use lots of kicker.

The stiffness thing does make sense. Minisail masts are bendy as hell, and don't break. Mind you, the fittings would pull out of the hull if Laser tensions were used.

Chris, while you are correct that many of the top sailors won't be selecting gear, there are also documented examples of those who will measure mast rake, weigh topmasts, etc. But the vast majority of Laser sailors aren't in either camp, or even doing local open meetings. They are sailing in their club handicap fleet on a Sunday and on a Wednesday night. Some won't even be aware that the Laser is an Olympic class, let alone that a plastic topmast is now allowed. Be interesting to see the reaction at clubs when the first ones filter down to our level.

Oh yes, there certainly are some sailors who are meticulous about their Lasers. It's just that the claims that you "need" new kit all the time are incorrect. It's probably a bit like the claims that in development classes you need a new boat every year or two - some of the top people get new gear regularly but it's not actually vital.

But don't the top sections break cos of the rivet weakening it, not the bending?

It used to be corrosion on the rivet hole and then the mast cracking along the line of it. You put the thing under a lot of tension on that rivet and it was rather unfortunate that it was always the upper one that went, which meant that the jagged edge came out of the collar and ripped the luff tube to add insult to injury, Why they didn't have the upper one at the back, cos that would have negated the issue a little.

As the owner of ancient boats, I'm not going to disagree on the "need" front, thats for sure. There is probably a psychological need, mind. I know I sail better with a recently polished hull, for instance, even though it must make next to no difference.

i do wonder how many of the tales of certain saolors being allowed  untrammeled access to  stock to obtain ' the best'  parts are  exactly that tales ... 

tht said any  wet layup  boat  will have variation in  weight  and balance ... 
but  not as much as other fibreglass  mouldings / modules in other uses where there was little thought or concenr  paid to  volumes  of materials used  (  sprayed  chopped  roving  + resin guns anyone )

Standard practice to keep the single rivet in compression although other thinking was that you should have it at the side.

It would have been very easy to design out the rivet.

I believe a design for a new collar that would achieve this was sent to ILCA and rejected.

It wouldn't have resolved the bending issue though.

I have known it happen, in a different class, not Lasers or 400's.
Imagine turning up waving cash, 'I'll take a new boat, but it has to weigh less than X'.

The bending my mast suffered was usually due to speed of the death rolls it suffered not due to excessive kicker. As for the rivet, well at one time the laser folks used to put a red arrow on the collar to line up with the red arrow on the bottom section which inevitably meant that the higher rivet was in tension
