IACC 120 Class

In other threats have been touching on the European IAAC 120 class which has been quietly growing out of Italy & France over last few years.

Claudio Diolaiti is the god father (mean that in the nicest possible way) who designed these beautiful racing yachts and along with many others I would acknowledge him as one of the most talented RC designer/builders of today.

Everything currently scratch built (few start selling hulls, sails etc) and the Italians have such passion for designing and building beautiful boats (like their cars) that sail like Ferrari's.

What is IACC 120 ? well take a look for yourself on these sites into this new wave European class
http://iacc120cup.altervista.org/Main0.html Italian site
http://iacc120cup.free.fr/ac_pages.p...20&height=1200 French site

The IACC 120 is supposed to replicate “almost” to scale 1:20 the America Cup boats. Overall length is 1200 mm, water length is no more than 1000 mm, the Sail Area is 80dm˛ maximum, it should be weighting 4500g minimum and the Fin+Bulb shall not be above 3000g (66%), the draft from the hull bottom is 420mm, Main Luff is 1750 maximum

Total freedom of construction materials not above lead density, for more, the IACC120 Cup "Class Rules" are attached.

On the Italian site there number of pictures and videos you can watch and is full of plans and other interesting details. Plans are free for non-commercial use so far and boats are replicas of a real America Cup Boats such as: ETNZ, Oracle, Alinghi, Desafio, ChinaTeam , Shosholoza and more...

AC 120 races are run in fleet and match racing format practically in the championship most of the race are fleet round robin and the top two winning boats racing against each other in finals, more or less the same as in real Americas Cup racing.

I’m becoming more & more interested in this class, are you? I'm starting researching learn more about this exciting new class of RC yacht racing. Have heard there are a few builds outside Europe in Canada, New Zealand & Australia and maybe more ... love to hear from ya!

Well , race practice is excellent until my sail hit the fan in the tent and tear the tip of my sail ...... what an unlucky day ..... i was avoiding the crowd in the tent than suddenly without realizing the mast was too close to the fan and ..... next thing i saw was a snapped back stay and tip of my sail creased and got a some what big hole. Geesh ......

Lucky did manage to patch that hole with dacron and hope that it'll not affect my performance .... but before that my boat got commented that it was quite fast and can keep up with the production boats ..... the only i could not chase right now is Azetone, Widget 09 ..... that's about it ... i hope this will continue tomorrow and the day after man ....

Hi Lamafever ... lol tough decision well me know what you finally decide.

In the mean time I will tempt your decision with attachments (in addition to plan above) which is everything you will need to get started.

I'm using professionally made sails from Todd at Isobar, nothing but the best at good prices, he now has template they will be ready in no time, drop him a line.

Cheers K1

Why build the old class? Go for the new AC33 class. The boats have much more potential, speedwise and look a lot better to boot. I have a copy here and there is a thread somewhere that has more on it. Take a look and think about it.

Dagnab it, can't upload the plans. If someone with better skills could post up the AC33a plans , ( I believe they're here somewhere )it would be most appreciated. This is the desgn I believe should be the next AMYA class and maybe even an international class. Lovely slim wedge design with an almost straight shear line and flat bottom, makes it a more attractive yacht and it should go like hell!

And why not go the catamaran/trimaran route - or too fast for the monohull sailors?

AC33 is not a class yet, this is a design by Claudio as an early concept boat,

Build log here starts post #45 http://www.rcsailing.net/forum1/show...?t=4991&page=5

But if you happen to know what the next generation of AC designs will look like, I would be very interested along with many others ? excluding the two horse AC trimarans Dick

Did you see the new Alinghi tri launch and pics ....unbelivably fast looking
