There are other 2 sailed boats out there...in fact, the market is pretty well served, especially as people choosing a boat without a spinnaker are unlikely to be going for ultimate speed, and established classes have a built in good racing circuit, generally. So with boats ranging from Firefly, Grad and N12 at the small end, through Ents and Tasars to the Albacore for the bigger boned, there is choice, but I think the Icon will offer something a little different, which gives it a chance. Provided enough people who want something a little different don't also want a kite to play with.

I'll certainly be wanting to jump into a demo boat and have a play when it all happens - it would be great to have a fast boat that is truly competitive on small lakes across the weather conditions.

Sorry, I hadn't mrant to hijack the thread, I was just struck by the superficial similarity between the hull shapes (and photo angles). 

I don't think boats like the Firefly and Grad are in the same market niche as the Icon.  I didn't know Albacores were still made?

Toby i hope you are taking the piss about the Albs dude!!

They are made by Ovington for a start and celebrate some pretty healthy nationals attendances as well as world and European champs (Not sure if thats proper worlds or just something the class has picked to call a champs)

Still its a big, active class.

The Albacores are having a bit of a resurgance right now, delivered our 12th boat yesterday since taking it on and have a further nine on order for a September build slot.

As well as the Icon, do not forget the MRX sold by our friends at Welsh Harp, basically a Merlin with no planks..

James, I think it was 22.2 knts not 30...how people exagerate!!

Sorry Chris, I didn't realise you guys made Albacores. Are they still wood?

But it was still basically a Merlin ....

There may be superficial similarities between hull forms but the NS root has been much freer since inception.  It is really about convergence of design - to produce  easily driven hull shapes (that do not have any nasty side issues !).  It is the rigs rigs that define each of these classes to a greater extent perhaps although I do think the MR could usefully experiment with wing sections given their existing freedom to do so.  The NS  evolved the wing mast approach  because for a set or rule limited sail area  they can and do prove more effective/competitive - and were permitted.   The reason we are going for a stick mast now for ICON is that we are not bound by a development design maximum sail area and can achieve a similar impact in a more straightforward manner - and it is easier for typical helms to read the sails effectively on a stick mast.  The Merlins are like the NS class, a limited sail area development class that does allow wing masts (but generally uses 'sticks' so I'm surprised that few have thought this an interesting area to explore - although I have had a couple of enquiries about our now spare wing sections and sails already !

The Merlin hull rules are a bit difficult to explain simply, but there is a good introduction here:
www.merlinrocket.co.uk/technical/beginners.htm
I assume the NS14 hulls are very different as their rules are freer.

With regard to Merlins with wing masts, whilst it all looks good in principle, everyone who has tried one has experienced failure, so thats why we still have 'sticks'.

Note that the original Merlins had wooden rotating masts! Plenty are still going. But I don't think it counts as a wing...

That's because everyone who's tried one has used a pear shaped section, and anyone who's researched the Australian development will tell you that was never going to work...

I think some fairly serious thoughtand effort has been thrown at wing masts for Merlins in the not so distant past? Not successfully. Not sure they all been pear shaped either?

At the end of the day, it's a highly developed boat that delivers close racing. That's what it's for, fleet racing, over a variety of conditions. and it does it very well. A class that delivers such good (quality and quantity) fleets at opens and championships will be a tough place to prove anything radical, unless it really is a better all round solution. You'd think extra 'free' sail (wing) area was a dead cert, but unless it's as controllable up to F6 and has no more weight aloft, there are down sides.

The Aus classes with wing masts don't seem to catch on here in the UK, not sure why. Possibly it's the no kite thing, which may only be marketable for 'simple' boats here, i.e. not too many rig controls, with the strange exception of the N12.

Perhaps when the Merlins and RS400's get blown away by wingmast boats at the major pursuit/handicap races over a range of weather, we'll be convinced.

To stumble back in the general direction of the OP, how much is a new Merlin?

both wood and plastic?

Which will never happen because there could never be more than a percentage point or so difference in performance. That will inevitably be swallowed up in all the other differences between boats and even more crews. The only situation in which the wing mast can show off its advantages and disadvantages is within a development class.

I used to be very enthusiastic about them back in the 70s and 80s, but as pole rigs have got more sophisticated over the years, and as we've learned far more about the importance of gust response and the like, I suspect, on limited evidence, that the potential advantages of the things are far less marked.

The other big problem is that they are complete sonofbitches to tune, so if you haven't got the accumulated expertise of folks like the NS guys to learn from its going to be a nightmare to get the device working to anything like potential. I suppose I should put one on the IC, which as a moderate sail area high efficiency boat ought to be a good platform, but I just can't face the devlopment work... I have enough trouble raising the enthusiam to so the work to add and subtract carbon from the pole mast to tune that properly...
