Neo 400 going fast downwind with not too much wind.

Yes, I know, some of you will be sayng: Another downwind speedster
except that this one, the Neo 400, it is not. It is a top ORC/IRC racer designed to have a good overall performance. I will be cruising but you guys can follow its performance on the world's ORC championship. It will be competing there.

Kuka-light, a fantastic video, a fantastic boat

Too much talk, today it seems we will have lots of videos and this one is absolutely fantastic:

A 42ft sailboat beating upwind a top Open 60!!!. Well that would not be out of this world if the boat was un upwind maximized one, but it isn't, the Kuka-Light is a kind of a 42 ft Open boat, kind of a 40 class racer a bit bigger and with a canting keel. They say the boat is proportionally 15% lighter than a top Open 60



The boat was thought and built by the crew with the help of a NA, Schickler Tagliapietra.

Here is the story:

The idea of creating Kuka-Light started to spin around my head when I realised that to improve the Rating of my boat I had to have smaller sails and make the boat slower. This is absurd for a yachtsman used to racing with A class catamarans and with Melges 24 boats. Speed and apparent wind are synonyms of fun for me so I asked myself: why give up on fun and give up having maximum performance?

I decided I wanted to feel the same sensations as when I am sailing my A class also on a keelboat made for demanding regattas such as the Middle Sea Race or Fastnet; building a 40 foot boat that is as light as possible and that uses the apparent wind to maximise its possible performance. I sent the rating to hell! As of today, I am still not totally sure of what we will manage to come up with and if our visions will be proven right. We’ll just have to wait and see.

...

The idea to create something special was following the Middle Sea Race 2009 when competing on a Cruiser/Racer (Kuka) Sly 42. We all enjoy racing and then asked ourselves why wouldn’t we just want to go fast and forget about handicap and rating systems. Why should we compromise our performance and make a boat slower just to have a better chance to win on handicap. This was going against the whole reason we take part in the Sport in the first place…To sail fast and have fun. Also all cruiser racer have a lot of compromises we did not want. If you are racing you need something created for it.

Kuka-Light, has been created with the fresh approach of not considering rating and handicap rules , but simply perform as best as possible for this size boat. The brief from the owner , a long time friend of mine was to build the fastest 40 ft monohull in the World that could take part in the premier ocean and coastal races and be easily sailed by 6-7 crew.

The brief went out from the following ideas:

1. To set up a crew is never easy and if you have a smaller crew it will be easier to find them and save a lot of money when travelling around.
2. The size of 40 feet was chosen as it is still a size which can be used by normal people, not a professional crew. Also the owner was always using boats of this size.

We started with a clean sheet of paper and applied many principles from our multihull background. The choice of the designers was crucial as we intended to create something different. So an established designer with experience would have problems to forget all what he had done before. In the same time we needed a team of designers capable to do a real race boat. Do to our multihull experience we decided that weight was the highest priority. This resulted in the end with probably the highest power to weight ratio keel boat ever launched.

We then formed a partnership with ST yacht designers who shared our vision of Kuka-Light.

I had already posted about this boat so if you look with the thread search engine you can find more.

LIONEL LEMONCHOIS his again with the right side up!

They reached him today (after living for 10 days on a capsized boat) and managed to put the big trimaran back on its feet. I bet Lionel is feeling a bit less miserable: He saved his boat
Faster and opc11 like this.

Maxi 1200

We have already talked here about the new Maxi 1200. Just some better images:

Re: Interesting Sailboats

Regarding the kuka light...
I am a little surprised that the kuka is with 3.2 t only 800 kg lighter than an plywood epoxy boat in her race trim one could build in his garage...
Didi 40cr radius chine plywood sailboat
And this homebuild boat has aluminum spars, 1.5 m less draft and 2 t ballast in a conventional keel casing made of steel... I imagine that the kuka has probably a little more than 1 t in her canting keelbulb...
If i look at the effort those guys put in to build the boat, i come to think that her lightness is not that extraordinary, just expensively bought...

And i know you cannot compare these two boats... The kuka has way more power, more sailarea and is by all means a lot faster... I just looked at the weight figures...

Isn't 20% or 800 kilo's still quite a lot, even more than the weight of crew + full gear?

Best regards,

Eric

Kuka-light is really very light:

I don't know why you say that the Kuka-Light has a little more than 1 ton of ballast. If we were talking about a mass market cruiser with the same characteristic of others a guess could be made, a relative one, but in what regards top racing boats that is hard to do. Regarding Open an 60's or a class 40 the box rule implies very similar ballasts to each boat but this one is truly an Open boat, following no rule. They don't give the ballast an that can go from 30% to 60%.Probably it is not by accident that they don't disclose the ballast.

Regarding the comparison with a DIDI 40, you are not talking about boats with the same dimensions. The Kuka light is not only bigger as much more beamier: more about 79cm in length and more 120cm in beam.

Comparing with a boat with the same type of hull and beam but smaller, a 40 class racer, for instance a racing Pogo 40 class (s2), the difference is huge: the Pogo with less 62 cm in length and less 10 cm on beam weights more 30% and that's huge considering the Pogo is a smaller boat.

Yes, a 42ft sailboat with a 4.6m beam weighting only 3200 kg is an extraordinarily light boat. Consider for instance that a A35 weights 4450kg and the Elan 320 weights 3690 kg and is one of the lightest boats in its class.

Regards

Paulo

Yes - that was an guess and looking at the bulb in all the images available, i do not see that it weighs in access of say 50 % of displacement...

What are you talking about?
The didi 40cr is just 10 cm shorter, has less beam but more freeboard and superstructure...

I am sorry, but you obviously did not get my point.
In plain: the keel construction and ballast alone weighs well over 2 t on the dixi...
That means that in race trim the whole hull plus hardware, rig and sails weighs less than 2 t... Can we agree on that?
I - and you - do not know, what the ballast ratio on the kuka is... But looking at the draft, one might think that the ballast will not exceed 40 % of didpl.
Why, you may ask?
Because "lightness" was standing in big letters on their design brief, as proclaimed on their webpage.
And the canting keel in combination with the big draft means a LOT of power from less weight.
And now go back to the homemade wooden boat and see that this nice little thing has so much weight in its keel and is still only 800 kg heavier... Strange hmmmm?
