They've created a monster! World's largest private yacht takes to the sea after £400m three-year construction project to build 590ft behemoth By Rebecca Seales (http://www.dailymail.co.uk/home/search.html?s=&authornamef=Rebecca+Seales)

This is the moment the world's largest private yacht took to the sea.

Azzam, which was built by German firm Lurssen, is a staggering 590 feet long - a £400million floating palace which has knocked Roman Abramovich off the owners' top spot.

It was officially unveiled for the first time in April following three years at the shipbuilder's docks in Bremen.

Yachtspotters have now photographed Azzam, believed to have been ordered by a Middle-Eastern billionaire, being tested on the North Sea.



Azzam has taken pole position as the world's largest yacht off Eclipse, a 533-foot boat owned by Roman Abramovich.

It can travel in excess of 30 knots, with power coming from a combination of two gas turbines and two diesel engines with a total of 94,000 horsepower.

Peter Seyfferth, from TheYachtPhoto.com, said: 'During the three days of trials, Azzam reached an amazing top speed of 31.5 knots, making her not only the longest but also by far the fastest megayacht in the world.

AZZAM'S VITAL STATISTICS Cost: £400million

Length: 590ft

Speed: Over 30 knots - it hit 31.5 in trials

Horsepower: 94,000


'Such a speed is absolutely exceptional for a yacht of this size.

'Her elegant, sleek lines are another feature which distinguish Azzam from all the other yachts above 150 metres.'
Mubarak Saad al Ahbabi was the engineer behind the megayacht, and assembled a team to work on the ultra-sophisticated project.

He was told by the yacht's secret buyer to build a vessel which was innovative and had a timeless design which would be able to travel at high speed and in shallow waters.

The exterior design, which has been described as 'surprisingly slender' was carried out by Nauta Yachts, with interior designer Christophe Leoni working on Azzam's inside.

Azzam is expected to be delivered to its owner later this year.

For anyone that still thinks the rich are not getting help from tax breaks and corruption need look no further.

31.5 knts...day-um. Conspicuous consumption to say the least.

31.5 knts...day-um. Conspicuous consumption to say the least.

By my calculations, hull speed should be around 26 knots. How they get that extra 5.5 knots means the vessel has to actually get up on a plane. Wow. I guess that's where the 94,000 horsepower comes in. I wonder what the gph is, maybe 200 gph at hull speed, and a 1000 gph at 31.5 knots? Just a wild guess. I don't suppose that billionaire even cares about full consumption.

When it comes to boats, less is actually more, imo. I mean, no matter how much money you have, how many bikini babes do you need?

If I won the lottery, I'd go out and buy this boat, a caliber LRC 40 foot. I was aboard one at a boat show and fell in love. Still very expensive, but you get what you pay for I suppose.

I hope he spent as much on fuel reserves as he did the ship.

To put things in perspective, the most powerful diesel locomotive GE makes produces 4,400 HP, that megayacht has as much power as 21 of these -

Bulbous bow. Creates a wave at 90 degrees out of phase that eliminates 'squatting'.

That 400 million went to employ quite a few shipbuilders.

Doesn't look like there's a bulbous bow on that vessel. While that might work for the big ships, it still doesn't explain fighting the waterline hull speed issue. That 5.5 extra knots, still is planing. Can't escape hull speed. Anything over hull speed requires massive amounts of both horsepower and fuel.

http://en.wikipedia.org/wiki/Bulbous_bow

A bulbous bow is a protruding bulb at the bow (or front) of a ship just below the waterline. The bulb modifies the way the water flows around the hull, reducing drag and thus increasing speed, range, fuel efficiency, and stability. Large ships with bulbous bows generally have a twelve to fifteen percent better fuel efficiency than similar vessels without them.[1] A bulbous bow also increases the buoyancy of the forward part and hence reduces the pitching of the ship to some small degree.

Bulbous bows have been found to be most effective when used on vessels that meet the following conditions:

the waterline length is longer than about 15 metres (49 ft)
the vessel will operate most of the time at or near its maximum speed

Palani, I know what a bulbous bow is. All the big ships have them. Fact is, the big ships do NOT go faster than hull speed. A bulbous bow has nothing to do with hull speed, and is likely useless when trying to push a boat UP on the bow wave...

Displacement is interesting. When a boat moves through the water, the water that is "pushed" out of the way, so to speak, actually goes around to the stern of the boat and pushes it forward. This is how you save fuel. By travelling at hull speed, the water you displace, actually helps push you along.

Hull speed is easily calculated based upon the waterline length of the boat. I based this on 400 feet erroring on the high side for this boat.

If you travel fast than hull speed. The bow of the boat actually wants to rise up on the bow wave. IE, you are trying to push more water out of the way than what the boat displaces. The whole weight of the boat needs to be pushed up on that bow wave essentially.

Folks, I made an error here. I calculated the hull speed wrong, based up 400 feet. This vessel is 590 feet, likely around 575 feet of waterline. Hull speed should be around 32 knot, recalculating. The 31.5 knot speed this vessel makes becomes clear now.

I am an idiot. Sorry for that.

Ok just don't do that again
