I believe they have chosen a specific carbon section so the bend charactieristics are the same as the current Ally stick (they would need to be or the sail won;t work as well). 

So the only real advantage will be weight high up (unless they have agreed that the tip weight must stay the same).

The Blaze is a class that manages incremental changes very well (in my experience) and older Mk1 boats are still very competitive if they have all the latest tweaks on them.

I have a lot of respect for the Blaze and it's class association, but the point is a boat with a new carbon mast is £550 more expensive than an Aluminium mast, or £1350 for a new mast, excluding shroads and lowers.
 
An Aluminium mast weighs aprox 1kg per metre and suspect a carbon mast a lot less, therefore giving an advantage even if it has the same or similer bend characteristcs, either it will end up going the same way as the Phantom's / Finn with respect to masts, in the end i suspect every one will need one.

agreed- development has been very well managed compared to all the other ex-90's Topper performance boats.  

Hopefully this isn't the straw that breaks the camels back though.  The Blaze has always tolerated larger people as well as 'Laser average'.  A carbon stick may well have the same luff curve as a tin rig, but it WILL have a different gust response.  This could signal the drop on competitive weights- that certainly happened in the Phantoms, but they at least allow multiple components from multiple sources, so stiffer carbon sections can appease the bigger chaps.

Allowing Carbon rudder stocks and foils, proably a little lighter but more expensive, this would start check book sailing.

Laminated (non white) sails, again pushes out the non check book sailors.
 
New boats are about £1k cheaper the a GP14, that's a lot of boat for your money!


Unfortunately the cost delta between carbon and aluminium is largely down to the retailers cashing in on what we all now perceive as necessary hi-tech. A 2m 25mm dia carbon pole for an Enterprise can be sourced or made for as little as £20 and yet the chandelries ask for £100. The mark up on Ali tube is knowhere near as extreme.

Ditto Fireballs in the Carbon department - that Twaron pole is an oddity! Modern Fireballs certainly and, I believe, Phantoms, too, benefit from exploiting existing class rules in terms of hull shape, tolerances and weight.

Carbon masts are not easy to introduce into a fleet, but when a new ali one is more than half the price of a carbon one, there is a lot of sense in it.
Carbon masts can at least be mended.
Also owners of existing boats can upgrade (perhaps if they break the ali mast), but you can't upgrade the lightness of your hull.
If the carbon mast keeps new boats selling that's good for everyone in the class in the long term.
In the medium term, it doesn't affect those that PY race against other classes, and you can always do what the B14's do, which is at least give the best 'tin rig' a mention in the write up.

'Updating' a class is hard to get right in my view.
It looks to me like the FRP Solo has really helped the class. Other classes you feel that meddling isn't going to help....
I haven't heard any laser sailors moan about having to buy XD kit to be competitive.

As someone who sails a cheap old boat, I don't worry that it costs me a place here and there. It's near enough the pace to have fun, and it's me and the crew holding it back 99% of the time.
If I wanted that extra %, I 'd have to spend a lot more and have everything just so.
Plus ca change and all that...

That's 'modern' meaning post 1970 for younger readers....
I'm sure when I was a teenager, there was endless debate about Oz Fireballs being a different shape and was it deliberate that they were not quite symmetrical...

 older plastic phantoms as well as the newer ones have all been made from the same basic mould (and only one of them at that), though I believe that the ovi ones have a couple changes at the transom, the shape is still the same everywhere else. As for exploiting the rules wi regard weight, nope, the rule has always been there regarding weight at a min of 61kg with a max of 3kg of weight. The difference with the epoxy boats is that they can now be built to these rules. There is no bending of the tolerances.

Due to the aforementioned the hull is probably one of the most one design ones around. The poly and epoxy boats share the same hull shape.

The main difference has been the introduction of carbon masts. I the first few years an Ali mast can still beat a carbon, but I don't know these days but probably. Agreed that the gust response is better though and it would suggest that the weight range of helms has increased. I fact in the seventies and early eighties you could get a needlespar that allowed for lightweight helms. They disappeared though and only the scaffolding poles remained, hence the lightweights moved away.

I had an ali mast for a lot longer than most due to economics and could still finish top 10 nationally. However I'm glad I have carbon now if only for handling around the dinghy park and that it isn't so cold on my hands in winter. That said it was a sealed one so that helped in the event of a capsize.

As a fellow Albacore owner I would love to have a carbon rig and non-Dacron sails. My experience of the Phantom is that it makes the boat so much more usable and enjoyable. I suspect this aspect gives as much extra speed as any technical speed increase.

And carbon booms are so much safer with regards to head-bashing - I'm dreading the day I get bashed by the heavy Albacore boom. Unfortunately at my height this is pretty much an inevitable event.

The Blaze CA voted at the last AGM for carbon masts to be offered as a option - by an overwhelming majority....  However it was for a one design mast that has been specifically developed for the class to work effectively with the standard North Mainsail.    If you keep everything standard and don't chase 'low weight at any cost' route and go for a regular round section you end up with a cost effective and durable carbon mast that, as has been mentioned already, be repaired rather than written off when damaged.

Some of us would have liked a carbon stick years ago but are now very glad the class waited  and made sensible decisions on the concept with the benefit of 'extra time'.  (We learn from the ... er 'issues' seen in other classes).   Sure it is always going to be a tough decision but the Blaze was possibly the last ('performance') singlehander to be launched with an alloy mast as standard in 1996.   A couple of years later and it would probably have had one from day 1.

We have had carbon booms since 2001 .. and like them this mast makes the boat more enjoyable to sail.   My own view is that the front of the fleet were already getting top performance out of the M7 and so will get the least gain from this mast option.  The back of the fleet will gain the most as it is more forgiving for sure and they will be able to press on in conditons they found more than tough previously ... and the middle of the fleet will find it easier to press the front guys now.  

Evolution in any 'one-design' class can be tricky - don't evolve and the odds on surviving many decades are pretty low ..  do it too quickly and you can lose the 'silent majority' already in the class. 

It will not transform the low wind performance as the boat is not optimised for that anyway - but it may mean more can storm around in more typical 'Blaze conditions' - staying out when many will be proping up the bar and grumbling about the excess of breeze ! 

Mike L.

PS - We do think GRF might just like it ... with or without spinnaker ! Wink
