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

YachtForums · 08-23-2004, 01:24 PM

Either this thing's got more acceleration than the Space Shuttle or they just launched off a rogue wave! My thanks to John Schmiemann at Millennium Yachts for supplying these pics as soon as the boat re-entered orbit.

Looks like they slowed down to their cruising speed, which is 45 mph!!

Looks like it could use some trim tabs.

Do they make tabs for a 140' yacht?!?

Looks like they'd need 10' x 12' sheets of kevlar and 3000 psi hydraulic rams to make a set of trim tabs for this beauty. That's quite a bow rise--I wonder if it was on plane or accelerating?

I've seen some other pics of the 140 running in the 40-50 knot range. It runs straight and level. The picture above must have been from an extreme tab position or maybe launching off a swell, however the water looks relatively calm in that picture. There's certainly enough horsepower under the hood to pull a wheelie, given the 75 mph this 140' monster is expected to hit.

Powered by a combination of Man/BW diesels and Lycoming jet turbines, all driving Lipps water jets, that kind of horsepower in conjunction with jet pumps could probably produce acceleration that results in a moon-shot bow rise.

That´s a nice one!! 140 feet yacht lifting of like that!! Anyone that knows were you can find more pics. and specs. of that "MELLENIUM"
Any homepage of the shipyard etc??

Just click on their banner when it pops up on YachtForums.

Look at the air it's getting in the first picture!!! I wouldn't want to be on the bow at that time, haha.

I read in one of my yacht magazines that it's range is 750 miles when at top speed (15,000 gallon tank capacity). That's 20 gallons a mile!

What banner... can't see any??

I think "Merle wood.." Florida is the agent for Mellenium but they don't show anything on their hompage.

As you click through pages on YachtForums, you'll see different banners with each page. They rotate randomly. There are 50 banners from 25 manufacturers on the site. When you see the Millennium banner, just click on it and you'll be directed to their site. Or, click here...

150 mph? Highly speculative and theoretically questionable. Jet pumps grow exponentially less efficient as speed increases....

Jet pumps are marvels of concentrated thrust up to certain speeds. Above these speeds (and this varies with hull design, weight and horsepower) jet pumps aerate. They do not run fully loaded at higher speeds. They ventilate, thus inducing air into the equation. Because the amount of water available for acceleration (remember water can not be compressed only accelerated) at higher speeds is reduced, due to the introduction of air, there is less water volume available to convert to thrust.

At certain speed thresholds (again, this varies), the hull will develope so much lift, that the vacuum created by the pump is no longer capable of bringing in the volume of water necessary to maintain adequate thrust, due to hydrodynamic lift shifting further aft and water trying to by-pass the intake gullet at higher speeds, which contributes to increased ventilation.

An enormous amount of vacuum must be generated to offset increased aeration, as speed increases. However, that same vacuum is creating downforce on the hull. This results in increasing hydrodynamic drag, further compounding the scenario.

Adding further complications to this fantasy.... 3 jet pumps. As speed increases, and thus hull lift increases, the outboard edges of the hull (or chines) run dry. The outboard pumps would loose efficiency very quickly.

The model is as far as the concept is going... sorry.

Sure wouldn't want to hit something at these speeds. I wonder what the hull layup is.

Hey Brian!

The listing sheet quotes aluminum. When you think about it, it's really the only logical choice. Steel would be too heavy and fiberglass would require a mold, which would be cost prohibitive, unless possibly... it was going into production. That's not likely to happen!

To marcusra... thanks for finding this and posting it!
