Can you make a yacht faster?

Hi,

If the boat has a planing hull you can probably add HP till you go so fast it goes out of control and crashes. The power to weight ratio is important so if ya want huge power and lo weight Gas Turbines are the way forward, they are not very economical at full power and even worse at part load.

It would be a waste of time looking through the floor at that speed you would be a lot better looking out the forward facing windows for sea life in the shape of other mariners an any immoveable objects in line with your trajectory.

As to cost, It is all relative if you have enough money to do what you wan then the cost is immaterial but rest assured it won't be cheap in any way shape or form except for the initial purchase of the boat.

Hi,

I am sure you could get a custom made yacht that went like that, as for off the shelf I don't know of anyone that produces them.

If I recall correctly there was either a boat or boats that were Gas Turbine powered about 15/20 yrs ago. There used to be an advert on the back of some of the magazines showing a guy in black and white with a Proto or Snap On wrench over his shoulder and some blurb about GT Power.

I want to say the guys name was Bob Allen or something like that.

Maybe one of the other Forum Members can recall this better than me

...."that's the formula for transparent aluminum...", "how do we know he didn't invent the stuff?"

70 knots? Sounds like the "yacht" would need to be a 75' Cigarette sliding across a frozen pond. Really, what would be the fuel per hour on that kind of rigged yacht??? 1000 gph?

My advice is to slow down and enjoy the ride.....fewer split cocktails.....just saying

google "acme rockets"... they make solid rocket boosters you can bolt on the side to get that kind of speed. i've seen that on TV a little while ago, I think it was a program called Roger Rabbit... or was it Woody Wood Pecker? very brighgtly colored graphic and sound effect. really nice set up.

An 83 doing 70 kts??? The real scary part is that some fool will probably do it and will probably drive it so far up on land that he'll then rent it out as a condo (and not one with a water view).

Hi,

I am working on a proposal for a guy to build a boat with a pair of diesel engines and a pair of GE LM2500G4 Gas Turbines.

These puppies punch out 47,370 shp each with a SFC of .354 lb/shp-hr or 16,768.98 lbs/hr or approx 2,345 US Gal of Fuel an hour each

I seriously doubt that one would physically fit into a Ferretti 830

Isn't the Millenium The World is Not Enough supposed to do like 70 knots?

Chick Corea

... so you're really putting us on with these questions, right?

Hi,

What you would gain in speed you would lose at the refueling dock (about every 100 miles )

I wonder if the hull of that 830 can even survive the stress of 70 knots in any weather...

For the love of God, at the very least be sure to trial the whole assembly before you try that world cruising thing.

Someone already did that with a 140' "The world is not enough"

Picture that hurtling through the fog or dark at you with an owner at the helm. The thought brings me back to the thread on SeaDoo for Dad as well as too many personal experiences.

was just thinking of them ... but in their sea trials, they lost control over 60 knots ...

i would NOT want to be in a 140' tri-deck doing those speeds ...

either that, or i should be certified & locked up ...
