Ankida experimental sailing vessel by Lila Lou London

Found on Pinterest:

The Ankida Yacht concept was developed aiming to move away from the conventional center-line arrangement by integrating the mast, keel and sail configuration with the hull naturally. The bow like arrangement of the vessel allows effective propulsion through the rig generated force. The sail layout and its operation have been designed to cover the surface area and best possible positioning to the wind condition and direction. Moreover, enhanced performance has been ensured by automatically adjusting the keel bulb to optimize the center of mass. The design relies greatly on the fully automatic operation mechanism; therefore a magnetically levitated turbine has been placed between the masts to provide power for the entire system which makes Ankida a unique and efficient wind powered vessel.


Each port, mast and starboard is running parallel, rather shadowing one another, which enhances the sail efficiency by covering maximum area. When the yacht is not with the sail, the booms remain joined with the aft and allow the sail to furl automatically in the line of the straight mast. Ankida can run under one sail too, therefore, the option of additional sails offer flexibility of pleasant cruising.

At least the renderings and presentations are first class
To maintain the ship with thousands of actuators must be challenging.
But after ships like Maltese Falcon or the new White Pearl I guess anything is possible.
http://www.lila-lou.com/gallery/?projectid=11

New to me ideas:
Twin keel with moveable balast in between.
Both port and starboards sails in a twin mast.
Top rolling spinakker.
Two twin booms with futuristic adjustment design,
controlled by a slidingdevice in the mast.

There is no "development".
This is just a fantasy.
Easy to write a few descriptive statements with no possible actual design/ mechanism.

Magnetically levitated is just a code word for wishful thinking.

I agree with you that a magnetically levitated turbine is far fetched.
The same for the booms. On the other hand the same was said from the Maltese Falcon rigging.

Why so negative? I like it when somebody tries something different, even if it may not be to the liking of "boat builders". If nobody tries something different, we would still have only T-Fords. As long we get at one of another stage a report how the yacht performed. Bert

Maltese Falcon exists, it has actually been built.
Some reports were not so positive on how well the rig worked, but I don't know of any factual reports.

Real developments of something different are valuable and desirable.

Fantasy renderings with no technical content are just comic books.
If there was a proposal on how to make the sails adjust to the tremendous variation in shape required there would be some value, even if a practical attempt failed or didn't work well.

New concepts are great, but it needs something besides the ability to draw in 3D.

I might as well draw Trump as an olympic sprinter.

What happens in a storm? There seems to be no way to lower all that gear.

Furling is mentioned. In the first seconds od the sailing video They show four elements of saile that folds out on each side.

About Malthese falcon; she was, just like the old square rigged tall ships, not able to sail high against the wind at a reasonable speed.

Most fascinating is the boom/mast construction of the ankida design.
What a momentum will be delivered at the dual twin mast. Extraordinairy materials and very carefull sailing will be needed to keep this construction intact.

On the other hand, why make the ship so large? Construction is only over complicated at that scale. If designed as a, let say 30 foot, experimental yacht I would say, Let's give it a try.

I'll try to contact Lila Lou yacht design about this.

You may furl the sails, but there is a huge structure that is fixed. The windage of all that hamper will likely capsize, or at least knock down the vessel in high winds.

Don't forget the moveable ballast underneath. But it will require constant monitoring, I agree. And a immmense amount of Procces Logic Controll to regulate all this. Plus the ammount of work to keep all this gear going.

Because in a way this sort of rubbish is actually very negative - the implication is that this sort of "superior" vessel is possible but people have not bothered to create it.

I don't know whether the model T Ford or any vessel was ever improved by someone ignoring the realities of design and construction. They were improved by people understanding the possibilities and the problems.

The same can be said about white pearl or any other superyacht.

This kind of projects delivers a good ammount of work and money.
And are a wonder to look at. But I agree that projects like quant are less prestigious.


Which of the following boats of the year 2016 was not a sort of "superior" vessel that is possible but people have not bothered to create it?

It's all innovation and you can't stop it.

Concept drawings,3d rendering are just the design equivalent of a hypothesis. You have to have ideas before you can test them. Some will work some will not.

With negative people like you, this design gets a tremendous publicity. I have respect for people who says, >>"what a different design. however they may have to do this or that, to make it properly sailing. They should make the beam wider etc. etc." The world is full of negative people and nothing gets created out of their hands, Except maybe copying somebody else works. Bert

Actually, Bert, the attitude I take is one taken by innovative, positive and successful people, including Einstein, Isaac Newton and others. As Newton said, "if I have seen further than others, it is because I am standing on the shoulders of giants" (or words to that effect). As Einstein said ruefully after his disastrous attempts to improve on aerofoils "this is what happens when a man thinks too much and reads too little".

The ability to respect those who have gone before, and to learn from them, worked for Einstein and Newton. Why can't it work from boat design too? A simple bit of understanding about the basics of sailing would have made the designers of this craft realise, for example, that it will not be able to sail very well dead downwind, as in the illustration with the "mains" wing and wing and the spinnaker in between. When there appears to be such a lack of any attempt to understand the way big fast yachts operate then the designers can be seen to be negative towards the many decades of development in modern maxi design, among other things.

I suppose I also can't see that imagination is really required if one is ignoring reality. One may as well say "hey I could make a boat better than this - all I need is ultralight unobtanium and I could give it a 500m high cat rig, 300m tall foils, and suspend an accommodation pod out to windward to keep it all up.....and I could have an infinity pool full of champagne on the top of the accommodation pod, and the wind would always be blowing 20 knots and the weather would always be sunny, and..."

Fantasies are easy to dream up. Imagining stuff that works better but can actually be created is surely the real challenge.

None of those boats ignores the reality of sailing and of materials science. They are the product of people learning from reality, not ignoring it.

The boat that the thread is about is different to the award-winning boats because it ignores the reality of even such basic issues as the fact that big, fast boats do now sail well dead downwind, and the issues with surface-breaking foils.
