New Millennium 140' - you've gotta see this!

For your curiosity I learned this from a cuple of books, when I was to write about the subject in college!!

I don't think I understod all the tecnical English at first!? SO the main problem with jets, is that they grow less efficient, because of the air getting into the system at high speeds???

Writing this I remember another fast Yacht, The 114' "Gentry Eagle". It was a project to beat the world-reccord cross the atlantic... It actually did in 1992 (62hrs 7min with topspeed of 69.6 knots!!) Nowdays it's refitted to a yacht with topspeed of 63knots. Anyhow this yacht has two V16 Diesels conected to waterjets... but the main powersource for high speeds, it's gasturbine is connected to an Arnesson suface-pearcing drive! Before this I thought a lot of why they used this configuration?. Parhaps it's just to get the power into the water in high speeds then??

Some drag boats do use waterjets and achieve speed over 200 knots.
But those boats do not need optimum fuel efficiency

So i do believe that it is possible to build a yacht that has top speed of 150 knots.

But that centaur design does look like it's going to have problems getting water inside those outboard jets when at speed.

I found some figures of Destriero;

She is 220´long and 42´wide
Displacement 1.000 tonnes
Engines 3 x 17.500 hp GE gas turbines with KaMeWa waterjets
Max speed 66 knots
Fuel 800.000 litres, Water 3.000 litres
Hull in aluminium
Range 3.600 NM at 54 knots...

There is something telling me that 150 knots is out of reach...

You're right on that one. That's for sure!!



Saw that you are located in sweden to!!
Parhaps you're a member of "KMK" ?? (KMK:U member myself)

Hi Marcusra...

I used to be a member of KMK and KMK:r in the past. I guess that you became a member in 1997 and I was there between 1968 and 1994...
By the way, today I was at their harbour and saw a drag/skiboat passing with a turbine and I think it had waterjet. I was first looking for a helicopter because of the sound, never heard something like that from a boat before. Maybe we have a 150-knot boat at our backyard...

Saw that one to!!! It was cruising around the boatshow in "vasahamnen"!! It looked like it would need quite flat water to be comfortable!??

Is the first picture of "The world is not enough" @ her 70 knots top speed?

About the 183 footer....

A modern diesel burns about .3 pounds of fuel per horsepower output/hour.
19000 hp would burn about 5700 pounds per hour or about 815 gallons per hour. 25000 gallons would yield a 30 hour duration.
Does anyone know what the burn rate per hp/hr is for a gas turbine? I thought is was higher than an internal combustion engine.

Not to mention that you would have to be running on glass seas to get anywhere near that speed....and of course, it would scare the hell out of you.

Dave

Yeah, right.

Sorry but we're not talking tarmac here. Maybe on a lake in summer. The Atlantic would break her back within days. Sorry to burst your bubble.

Typically a turbine burns 8-12% more fuel than a piston engine. Around the docks too. For some performance turbine boat owners this is unacceptable, and they mount small(50hp or so) outboard motors with jet pumps between the turbines. When they come off plane, before entering the dock area, they will stop the turbines and use the outboard to dock with. A 200mph 40' Skater catmaran in NJ has this setup.

Millenium

The turbines lose 10 - 15% of power during hot weather, and runs ideally during cold weather.
I preffer diesel engines with bigger horsepower than turbines, but that's my opinion.

I've been on Millenium couple of times and as a yacht she is very nice, don't like much interior lot Versaci furniture etc. too much for my taste. Other thing is that when you are on board, you have a feeling as she moves left - right that you are in 50 foot boat rather than on 140 ft. but that's the sacrifice for speed.

She is an excellent project flybridge yacht with 65 max speed it is awesome.
But for sportish and fast yacht i would rather choose an 150 ft open like Mangusta, Leopard, AB, Tecnomar, Pershing.......their interior is quite modern than on Millenium.....and performances can be customised.....

At what speed does TwinE acheive a range on 3000nm?

I can't seem to find the price of this beauty. Anyone know?

Here it is;

Thanks so much.

M-140 (TWINE) engine room

I have seen some photos of redesigned TWINE. I don´t like the way it looks now, but it is the matter of the personal taste. It reminds me of the attractive sport car, now transformed to Station Wagon version. I have also some objections on its propulsion package: I think that two more modern and more powerfull, Vericor TF50 (TF100 configuration with common gearbox and combine output of 8.135 kW/11.064 mHP) should have been used and installed instead of two TF40´s (TF80 configuration with common gearbox and combine output of 6.770 kW/9.207 mHP), but I´ve heared Mr. Staluppi already owned one TF40, so they just added the other one. AllenGears gearbox, by which two TF40 turbines are connected to central Lips LJ84E waterjet, although awarded for its construction, has one real limitation. It does not have SSS clutches so if one of turbines already works at high speed, you can not add the other one?! Turbines must be used as an operating pair, or one or the other.
Although I prefer MTU highspeed engines, which represent the world for its own, I have no objection on Paxman 18VP185 engines (4.000kW/5.440 mHP). Great engines, compact dimensions, lightweight....very popular in its time and now out of production!

Have anyone seen this as yet?

It is a segment from one of two shows on superyachts the Travel Channel plays almost monthly usually back to back. My cable guide says they are from 2004. One of the two shows features Lady Lola with the famous quote Mrs. H. related from her husband, "Where's the blue?" We also get a few moments with Stan Antrim as the yacht is discussed and Mr. H. hits a few golf balls of the aft deck.

Yeah I watched the one with "Lady Lola" but never seen TWINE one, quite fascinating but I think i vaguely remember Carl talking about the situation with TWINE and her stability at high knotage sometime back.
