This boat will be at the Ft Lauderdale show, 75 Express with quad diesels and joystick controls. Awesome!

Re: New Lazzara 75 Express with IPS
Interesting. However, the claim that at 35 knots she runs faster than competitors with twice the horsepower is incorrect.
Firstly, competitors rarely have twice the horsepower. Most express cruisers of that size and type are powered by twin diesels between 1200 and 1500hp. by MAN, MTU or CAT. Only performance-oriented cruisers like Pershings and Baias of that size have MTUs of 1800+ hp. But they are pushing 50 knots. A comparable hull in terms of size is a Sunseeker Predator 75 or the new 72. The old 75 will run close to 35 knots with twin MAN 1200s on conventional shaft drives.
Therefore, in terms of pure performance, it's good but I would attribute this more to the relatively narrow beam than to the IPS drive. The boat is almost 77' overall. Most modern yachts of that length would have a beam of approx. 20' rather than 18'2".
However, in terms of safety and fuel economy, the advantage is obvious. I have been advocating the benefits of quad smaller engines vs. two bigger engines for quite some time now and have convinced myself with our 50' with quad Yanmars. If they can get a 400 NM range with 830 gallons of fuel, then this is quite something. 400 NM is just about the range that other manufacturers of similar boats are shooting for but they usually have twice the fuel capacity.
And if the boat can still plane on three and even two engines, the advantage for long crossings is obvious. It would be just interesting to see whether she can get on plane on two or three engines because staying on plane and getting on plane are two very different things. And when you do break something, you rarely stay on plane and continue on your way as if nothing happened.
