Perini Navi's 'Art Explorer,'

Commissioned by Art Explora, it's the world's largest sailing catamaran, with a length of 46.5 meters, a width of 17.30 meters, and a 50-meter mast.

The flybridge will host virtual exhibitions, while the central part will house the gallery for the inaugural digital exhibition 'Icons' on women in the Mediterranean.

On the roof of the deckhouse, have been installed 65 square meters of solar panels, allowing an instantaneous production of 12 kW and a total energy accumulation of more than 200 kW each day.

The design is by Axel de Beaufort and Guillaume Verdier.

Lamborghini Asterion LPI 910-4 (Concorso d'Eleganza Villa d'Este) 

In Greek mythology, Asterion is a second name for the Minotaur, a hybrid creature with the body of a man and the head of a bull. The name chosen was especially successful.

The Asterion defines a solution to significantly reducing CO2 emissions through innovative technologies. It features a high performance hybrid system with a V10 5.2 litre longitudinally-placed, naturally aspirated mid-engine which, in combination with three electro motors, provides a maximum power output of 669 kW (910 hp). Asterion accelerates from 0-100 km/h in 3.0 seconds, with a top speed of 320 km/h. The Asterion LPI 910-4 guarantees unique Lamborghini driving feel with a smooth and reactive driveability and superior power. The vehicle doesn't allow only an exceptionally low CO2 emission of only 98g/km, but more importantly for city driving, the Asterion has a pure electric range of 50 km.

Conceived and developed entirely in-house by Lamborghini, the Asterion LPI 910-4 takes the design and cutting-edge engineering expertise found in the current Lamborghini product range, adding innovative hybrid technology, and thus creating a Lamborghini that is clearly different – with a new, unexpected and sensual design, in line with the technical characteristics of the car – but yet still unmistakably a Lamborghini. 

In the aesthetic section, there was no doubt that it was a Lamborghini prototype, although the designer Filippo Perini, creator of the Aventador, the Urus and the Veneno, resorted to a 'neo-retro' style, quite original and attractive, under my opinion Unfortunately, this project did not spawn a production model. Also in 2014 the Urus concept car was presented and it is unnecessary to explain which vehicle focused all the efforts on the part of the Bolognese company...

Even before al the bodies have been recovered, the blame game is in full swing over Perini Navi's 55m Bayesian that went down in a storm off Porticello, Sicily. I read this morning the chief of the group that owns Perini Navi came out swinging, putting the blame squarely on the crew.

There's a good technical analysis from designer Chris Feers below the cut.

TL;Don't want to read: Monohulls of all stripes are designed to survive a knockdown; Perini's engineering is some of he best in the world. Bayesian had a retractable keel which could shorten her 32' draft to 12'. With the keel extended, meaning she had full use her counterweight, she would have been able to right herself in a full knockdown. Even if her mast were below the waterline, even if she lost her mast, maybe more so if she lost her mast, assuming she was watertight, her design would allow her to self recover. With the keel retracted tho, her righting moment would be dramatically less. If she wasn't watertight, a knockdown would be unrecoverable and she would, as she did, quickly end up on the bottom of the ocean.

I have so many questions. We won't know the full story for a bit but seven people losing their lives should have been an avoidable outcome.

This is a one in a million tragedy but we should examine the facts and learn from them. Bayesian boasts the second highest mast in the world at 75 metres on a length of 56m. She has a lifting keel to enable her to get into shallow areas. Fully down it gives a draft of 9.83m and raised a draft of 4m. A sailing yacht has a keel to counter the heeling moment generated by the power of her sail plan. I’m sorry to say that size matters to a superyacht owner and naval architects are seduced into providing solutions. As yacht size increases the resistance of the hull reduces in proportion, so less sail area is required to adequately power longer yachts. But these floating fashion items are driven by appearance and bragging rights - and you lose prestige if someone has a bigger mast than you. Always the status pecking order questions are – how big – how fast – what cost – and is it black? If you designed Bayesian with a reasonable sail area and a ‘normal’ mast she would not look impressiive – which is what superyachts have to be.

The stability of a yacht has to be sufficient to counter the power of the rig but, as mast heights increase, the keels can often become so deep that the places of interest are restricted hence the lifting keel solution. Stability comes from two factors – the hull form and the ballast keel which acts like a pendulum. As the yacht heels the volume of the immersed hull section produce a buoyancy force which resists heeling. Initially the keel gives little force but as the angle of heel increases ‘physics’ makes the keel contribution significant (leverage). The greater the keel length, the greater the effect. The combination of the hull buoyancy on the heeled side and the keel on the ‘windward’ side produces the force necessary to keep the yacht from capsize. If the keel of Bayesian was retracted it would lose a significant six meters of moment arm or leverage from its probable 200 tons of keel bulb. When we design yachts we calculate the stability, or righting lever, as a function of heeled ‘bouyancy’ force and the ballast moment arm combined. (the GZ) This can be plotted on a graph to show the stability at any heel angle and identifies the angle at which stability becomes negative causing the yacht to capsize.

Normally an ocean yacht will experience a negative point at about 120 degrees of heel. With a lifting keel this point is greatly reduced maybe to less than 90 degrees. If Bayesian was at anchor with the keel raised and no sail up the crew would have every confidence that she could remain safe in most normal wind conditions. Every captain at this level has passed an exam on stability and would be aware of his vessels stability graph.

Many years ago I sat at Cremorne and watched a spiralling williwaw race across Sydney harbour and pass through Mosman. This twister was only about 30 metres wide but it destroyed houses and overturned cars in its path. A few feet away nothing was harmed.

The power of a twister is intense and powerful with the wind is coming from every direction. This was what hit Bayesian. The problem of large rigs is windage, even with no sails. But this yacht had three furling sails forward and a big boom with the weight of a furled mainsail inside all above the centre of gravity. Also there were a few communication domes on the spreaders.

We use a wind pressure coefficient to measure the force of the wind on the rig and sails. Even without sails the WPC for Bayesian must have been pretty large when hit by a wind force of varying direction with a local velocity way above the norm. Once she was knocked down beyond her stability limit with the keel up she stood no chance and, laying flat to the water, her deck openings would have allowed a flood of water aboard and she would founder. This would happen in a couple of minutes.

The observation of a lightning strike can be discounted because these vessels are grounded and any damage from a strike would have caused a slow sinking at worst – not a capsize and founder.

The individuals within a professional crew with sailing experience may have sensed the wind and motion of the vessel and quickly reacted to instinctively save themselves in the seconds they had. My guess is that some were already on deck alarmed by the general conditions.The guests would have found themselves totally disoriented in flooding cabins, in darkness with the walls, doors and passageways at ninety degrees to the norm. They had practically no chance because it would be completely beyond their experience. The crew would have been unable to be of any help due to the speed of the unexpected event.

I have been a professional yacht designer and builder for fifty years specialising in lifting keel yachts. My son, a professional navigator, was Third Officer on a ketch superyacht with masts 100m tall; a yacht so big, at 88metres, that it was almost beyond human handling even with the machinery on board. But of course it is the biggest and most expensive’ etc etc. What we have here is a one off accident which is a wake up call to an industry where common sense has departed as yachts get more silly in size and design.

In summary Bayesian was caught in the wrong place at the wrong time. A freak accident which the designers and crew would have little chance to predict.

If the keel had been down she would have probably survived the knock down. But without sails up the crew would have experience of her basic stability for normal conditions which would have felt adequate. Any enquiry must examine the design factors such as the stability vanishing point in the condition she was at the time of the accident; keel up, tank loadings and rig factors for windage (WPC) and centre of gravity etc. And a calculation of the wind force required to heel the boat to 90 degrees in the condition at the time of the accident.

All forms of transport have had these unpredictable one off events leading to changes of regulations and professional practice. Titanic, Boeing, 1955 Le Mans, the 1952 Farnborough crash, the 1979 Fastnet – all have made a difference and these events all came unpredicted and out of the blue often at a time of complacency.

Who jinxed the morning?

First this dude won a bronze

but apparently forgot to take the phone out of his boat bag and bringing electronics is very much frowned upon so he got disqualified;

then in archery this happens:

and he lost his arrow, his aim, his concentration, his semi-final and to cap the day, his bronze final as well.

Gloria Steinem by Mª Isabel Sánchez Vegara. Illustrated by Lucila Perini

Age Recommendation: Early Primary Topic/ Theme: Equality, Biographic Setting: America Series: Little People, Big Dreams

Rating: 5/5

Gloria Steinem is a bit (ok a lot) of a controversial figure, any woman who is as deeply entrenched in the feminism movement as she is usually are. This represents her in the best possible light, showing her strength and all the good she has done for women and minorities in the world. The inclusion of the reference to "A Bunny's Tale", Steinem's 1963 Playboy expose is definitely one for the adults. Those iconic ears will mean nothing to young readers.

I like the choices for the consistent design elements of Steinem. Originally I thought there were three but there are only two, the glasses and hair. The one that changed quite late was the colouring of her clothes usually autumnal reds. The art style for Dorothy Pitman Hughes, co-founder of Ms. and frequent face in Steinem's fight for equality, is done well. That last page containing the book's lasting message is fantastic. There are minorities and togetherness, and an adorable Dachshund.
