Mysterious Spider Boat Appears Out of the Fog

New Concept of Ocean-Going Catamaran Is Being Tested

















The story so far has an element of mystery:

The weird boat was first sighted coming out of the fog and docking at the Port of Ilwaco on the Washington State coast. Soon the first pictures began to circulate on the internet (mostly by email) with the following text:

"An entirely unheard-of, twin-hulled watercraft with no markings is photographed by a bystander in the Port of Ilwaco on the Washington State coast. Those guarding it refuse to answer questions about what it is, or where it came from."

It was suggested it may be something Boeing is working on. The pontoons appear to be made of very thick rubber and may be fuel cells. Note that each of the steel spider-like legs are jointed in three places. Perhaps the boat can be lowered in calm seas and raised when it is rough.

The boat had no name or number..."
Then Urban Legends site picked up the story investigating if it's a myth or not. More sightings were made of the boat (in San Francisco Bay and around Anacortes), and their conclusion was:

"The pictures are authentic and reveal the prototype of an inflatable power catamaran designed by Antrim Associates based on a concept by oceanographer Ugo Conti.

According to Yachting Monthly, the experimental vessel is 100 feet long and 50 feet wide and powered by twin diesel engines mounted to the rear of the inflatable pontoon hulls. The cabin is suspended on flexible legs about 15 feet above and between the hulls, allowing them to glide independently over the service of the water. It is capable of crossing oceans with as much, if not more, stability than a normal catamaran."

If this concept proves worthy, then we may witness the evolution of conventional boat shape into something entirely different (think along the "War of the Worlds" spidery lines). US Navy has explored catamaran shape before. Below are the pictures of a huge ship, "HSV 2 Swift", a high-speed catamaran used today for mine countermeasures and as a sea-based test platform. It proved to be really fast and reliable vessel.

The Biggest Ships in the World

Supertanker Knock Nevis/ Jahre Viking - big ship with a big story
This is the king of all supertankers, and possibly the biggest ship ever constructed (see French tankers on page 1, competing for this title). However, it is certainly the BIGGEST SHIP still in operation (albeit as a "floating storage and offloading unit" only). There is also a larger-than-life story associated with that ship.

First of all, it had more pseudonyms than Alexandre Dumas:
- "Seawise Giant"
- "Porthos"
- "Happy Giant"
- "Jahre Viking"
- "Knock Nevis"

Built in Japan in 1979 for a Greek shipping magnate, who went bankrupt shortly thereafter, she was sold to the Hong Kong owner, who promptly increased her length even more. In 1981 "The Seawise Giant" was born, biggest among ships.

At first, she operated between the Middle East and the USA but from about 1986 she was used as a floating storage ship and transhipment terminal in Iran during the Iran-Iraq War. In May, 1988, the ship was attacked and heavily damaged by bombs dropped from Iraqi jets while lying at the Iranian Hormuz terminal in the Strait of Hormuz.

But the story does not end here. Miraculously, she gained a second life and a full restoration! "The Sea Wise Giant", or what remained of her, was bought by a Norwegian company, re-floated, and towed to the Keppel shipyard in Singapore. After major conversions and repairs she was relaunched in 1991 first as the "Happy Giant", and then as the "TT Jahre Viking". Here is a photo of restoration (click to enlarge)

In March 2004, the ship was sold again and sent by her new owner to the Dubai shipyard to be refitted as a floating storage and offloading unit (FSO). There, she was given her current name, "Knock Nevis". On the following photos we see her arrival at the docks - the final sea voyage of the great and legendary ship



The Heart of a Giant

Take a look at the biggest diesel engine in the world: such technological marvels are required to move the huge ships as Knock Nevis, or Emma Maersk

Stealth Ships

"M-80 Stiletto" - Radically Designed Ship for the Special Operations Forces

The M-shaped revolutionary hull of the "M-80 Stiletto" gives it very good stability at high speeds in shallow water, combined with great stealth.
It's a lightweight, all-carbon ship; 80 ft in length; designed for speeds of 50-60 kts (nearly 60 miles per hour) and powered by four 1,650-horsepower Caterpillar engines.









An additional air cushion is formed underneath the ship using the recaptured energy of the bow wave.
This breakthrough hull design allows it to achieve an exceptionally smooth ride at high speeds in rough seas. It can also launch multiple unmanned aerial vehicles (UAV) to provide reconnaissance data, relayed to the "clustered" supercomputer on board. The vessel has the ability to navigate shallow rivers, chase bad guys at 60 miles per hour and can even be outfitted with jet drives for beaching.

"“We are confident that the M80 Stiletto’s design is superior to all other existing technologies. Nothing else is out there that can achieve the qualities important to brown water vessels at a relatively low cost with short design and production cycles"
(source M Ship Co.)

2. "Sea Shadow" - legendary "movie star" stealth boat....

The program began in the mid-Eighties, when the ship was built in secret in 1985 and later used for various clandestine purposes. It was revealed to the public only 9 years later, in 1994. Since then it has become an icon of radical boat design, and is easily recognizable - it was prominently featured in the 1997 James Bond movie "Tomorrow Never Dies". The interior of that villain's ship showed all kinds of luxury and accommodation, however in reality the boat only has 12 bunks, one microwave oven, a fridge and a table.

Recently "Sea Shadow" has been reactivated by the U.S. Navy; it will become part of the "DD 21" program, supporting the new Navy's 21st Century Land Attack Destroyer. If you have not heard about this development yet, here is an update

New Hydrofoil & Submersible Concepts

Modern Italian Design + Great Efficiency

Guillermo Sureda-Burgos is a world-renowned stylist and designer, who creates new concepts for underwater transportation devices, as well as some striking furniture & appliance designs. He also teaches advanced computer graphics in the Industrial Design department of the Art Institute Fort Lauderdale, and the Canary Islands, Spain.

The following images were graciously provided by Guillermo - exclusively for Dark Roasted Blend - as an overview of his latest concepts and design ideas:

Hydrofoil Boat Concept

High Speed Surface Craft. Modern concept for an business jet alternative operating on busy coastal areas, serving four passengers.












Guillermo's aiming to replace business jet travel with his boat; but in recreational boating he is up against Pininfarina's recent concept of Hydrofoil Sailing Yacht (reaching speed of 32 knots).

Personal Submersible Vehicles

So called "dry-pressurized" submarines have passenger compartment separate from the water and at sea level pressure; the space between the vehicle and the outer hydrodynamic skin floods with seawater during submerged operation. The submersible's layout is similar to the standard seating arrangement of a passenger automobile. XS100 Duo seats two and XS100 Trio seats three submariners. The intended market would be luxury yacht and resort owners, those who are perhaps bored of a luxury yacht and wanting to try something new (the price of a 2 passenger model for a target depth 100 meters should be close to that of a limited production exotic sports car, i. e. around 400,000€. With the larger production numbers the price can come down to 150,000€). The subs eye-catching design seem to be firmly rooted in the best of a Fin & Chrome style of the 50s.

XS100 Duo Beta Personal Submersible











For the next personal submersible concept Guillermo thinks of compementing individual pressurized sub performance with hydrofoil high-speed mode. Definitely something to watch for!

The Last Victorian Leviathan Steam Ship

The More-Than-Great "Great Eastern"
- one of the most spectacular ships ever built!

Take a good long look at this ship. Built in 1858, it was capable of bringing 4,000 people around the world, without ever once needing to refuel...

An Iron Monster, framed in a cloud of billowing white sails, or looming through the hellish black smoke - this was the ultimate Victorian luxury Trans-Atlantic liner, affectionately called the "great babe" by its eccentric designer:

An introduction to Victorian grandiosity:

The Victorians - and so you don't have to look it up, means the British and U.S. during the reign of Queen Victoria, from about 1837 to 1901 -- did some truly great things. Theirs was an glowing-brass and crusty-iron era of chugging, whistling, hissing wonders. Nothing, they seemed to think, was impossible: the answer to every question, every engineering challenge, was just the matter of finding the right kind of steam engine for the job.

One of their greats was the legendary Crystal Palace


Although the Palace wasn't powered by coal, it was certainly fueled by Victorian mechanical audacity. Originally set up in Hyde Park in 1851 for the Great Exhibition, though later expanded and moved, the Palace was a transparent monster of a building, a huge greenhouse made up of 900,000 square feet of glass supported by an iron framework.
900,000 may not sound like much but keep this in mind: the Palace was home to more than 14,000 exhibits. The Palace was something no one had seen before, a precisely engineered celebration of British innovation. The future had arrived in Hyde Park, and it was a tomorrow of crystal and steel.

Another Victorian great was ... well, it might not have been as spectacular as the Crystal Palace but it was still something that made the people of London sit up and take notice. Or perhaps sit down and take notice. We take sewers and such for granted now but back then it was a true technological miracle, especially when executed on giant Victorian scale. Before Joseph Bazalgette began his work, London was a filthy nightmare. Decades, and more than 1,000 miles of pipe and connections later, the great city had become a marvel of cleanliness: a tomorrow of (mostly) clean streets and sweet smells.

An iron-riveted mountain, a black-smoke metal volcano

Like with those 900,000 square feet of glass or 1,000 miles of sewer pipe, just prattling off the numbers doesn't do Brunel's Great Eastern justice. Its true scale can be better appreciated from these construction photograph




The Cable Ship

But the Great Eastern's most famous job wasn't shuttling passengers across the Atlantic. The Victorians had a great fondness for boilers, condensers, pistons, furnaces, and the stacks of steam power, but they'd also begun to harness the power of lightning -- or at least enough of it to send dots and dashes across a wire.

The telegraph was a revolution but it was mostly limited to the continents. If you wanted to write Aunt Joan in New York you still had to put pen to paper and trust the post. Until the Great Eastern laid the transatlantic cable.
Time for numbers again: 2,600 miles of cable is what the Eastern carefully laid out across the Atlantic and later, across the Indian Ocean. Twenty-six-hundred miles when one kink, one break, would mean having to start all over again. That's a tremendous endeavor to try even today, let alone when men wore stovepipe hats and horses were still the preferred method of traveling on land.


Two great ships: the "Great Eastern" & the "Titanic".
Both suffered a damage to their hull.
One sunk, one didn't.


SS "Great Eastern" was also incredibly modern, boasting double hull construction (far ahead of its common use) and even gas lighting. It is this DOUBLE HULL that kept her afloat in the same circumstances that sent the "Titanic" to its doom. Here is a comparison with the Titanic:

- Both the Titanic and the Great Eastern were the largest ships of their time.
- Each suffered nearly the same accident, with utterly different results.

- The Great Eastern featured fifty water-tight compartments, and a maze of bulkheads.
- The Titanic's hull had only a single wall on each side!.. And even though the hull was divided in fifteen sections, which were designed to be sealed on a moments notice, "the bulkheads between those sections were riddled with access doors to improve luxury service".
The Great Eastern suffered a huge 83-foot-long, 9-foot-wide gash, after the encounter with an uncharted rock in Long Island Sound in 1862. But the inner hull held, and the ship remained afloat.

The Titanic did not suffer anything like the huge continuous gash in the side of the Great Eastern:
Titanic's hull "had not been gashed at all, but had been punctured in six of its forward compartments with a series of thin slits amounting to no more that 12 square feet."

The Biggest Ships in the World

1. Freedom Ship - a futuristic dream that just might come true

I remember seeing similar illustrations in some vintage popular science and sci-fi publications, depicting the floating city concept in a truly mind-boggling way. I did not think for a minute that I might live to see these projects given serious consideration and being actually on a brink of being built.

According to the official site the projected "Freedom Ship" may look something like this.

Imagine a mile-long stretch of 25-story-tall buildings in New York City; now imagine that floating on the water.

"The Freedom Ship has little in common with a conventional ship; it is actually nothing more than a big barge...But what if this tremendous barge was assigned a voyage that required slowly cruising around the world, hugging the shoreline, and completing one revolution every 3 years?" There is even talk about making this city an independent country.



Incidentally, the "Freedom Ship" will possibly also be the largest man-made structure on Earth, which puts it in the same category as the Tower of Babel. It will be extremely vulnerable to a spectacular downfall, even if miraculously built (the last update on the site is from February 2005, when everything still revolved around financing) For now we can just dream on, looking at the pictures.

Notice the similarity of the above concept with the 1928 model of an airport on top of a giant building! Los Angeles architects expected private planes to replace automobiles in a near future; hence this 300m-long roof-top airstrip




Misperception: "Freedom Ship" aircraft flight deck can accept 747 aircraft.
Facts: The largest aircraft this flight deck can accept are turboprop aircraft in the 38 to 40-passenger range. (Oh well, here goes the "wow" factor...)


2. More Cruise Ship Concepts:
some of them will dwarf any other ship in existence

- Kvaerner Masa-Yards' Super-Large Cruise Ship (on the left) and The Nova, a Panamax-Max ship displacing more than 100,000 GT (on the right).

3. The Biggest Ships Ever Constructed - Supertankers Extraordinaire!

The biggest ships ever constructed were four supertankers built in France at the end of the seventies, having a 555.000 DWT and a 414 meters length. They launched from the shipyard Chantiers de l'Atlantique at Saint Nazaire. The only larger ship was the jumboized "Knock Nevis"; ex "Jahre Viking", ex "Seawise Giant", ex "Porthos", in 1981 (see entry in Part 2). However, the Batillus class had the greater gross tonnage per ship, and it could be argued that they were, in fact, larger than the Knock Nevis.

* Batillus, built in 1976, scrapped in 1985.
* Bellamya, built in 1976, scrapped in 1986.
* Pierre Guillaumat, built in 1977, scrapped in 1983.
* Prairial, built in 1979,
(also as "Hellas Fos" and "Sea Giant") scrapped in 2003

So here is "Pierre Guillaumat" - Biggest Ship Ever Constructed
