Ferretti Mochi Craft 75: Promises Zero Emissions
Mochi Craft 75-footer with an intriguing and innovative propulsion system, could be the world's first "zero-emissions" yacht.
The Ferretti Group’s Mochi Craft division is heralding its new Long Range 23 as “the first zero-emission mode motoryacht over 20 meters.” That’s nifty stuff in today’s enviro-friendly world, and it should be a big selling point as Mochi Craft—previously known for its lobster boat-style Dolphin design—enters the extended-cruising market with this 75-footer.
There are two components that make the zero-emission propulsion possible. First is what the builder is calling a FERWEY (Ferretti Wave Efficient Yacht) trans-planing hull. Yes, that’s a mouthful, but the upshot is a hull that Ferretti says eliminates typical stern-down attitude when speed increases. Designers combined that improved performance not only with the anti-rolling gyro system on other Ferretti models, but also with the builder’s new hybrid propulsion system. It lets you operate in five modes ranging from traditional diesel to zero emissions using a combination of diesel and electric engines, an inverter, batteries, and a generator.
According to the synopsis, a pair of 70-kW synchronous electric motors are applied in series to the propeller shaft, engaging with the reduction gears. Those motors are powered by a pack of Lithium ion batteries that store energy the diesel engines produce under way, or that can be charged via shore power. This means that for short cruises, you could operate the Long Range 23 on electric power alone, and that for long cruises, you can recharge the batteries while moving in and out of diesel mode by using the touch-screen panel at the helm.
The builder says the new boat will cruise at 13.5 knots and hit a top speed of 16 knots with 800-horsepower MAN Common Rail engines. There’s no information about how those speeds might change when operating in various earth-friendly modes, but I know I’d give up a knot or two now and then to keep our oceans and sea air cleaner. Hopefully for Mochi Craft, a lot of other boaters feel exactly the same way.
