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.

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.

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?

Thanks so much.

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!
