Who wrote that, 50m yacht can do what with what? from the front page
"The 50-meter (165-foot) yacht costs about $38 million. A new hybrid mode allows it to travel at 9 knots in virtual silence for about 9,000 miles using less than 12 gallons of fuel an hour, compared to about 26 gallons per hour when it’s travelling at 12 knots with its traditional motors on. In the hybrid mode, it uses diesel generators to power electric shaft motors instead of batteries, according to Conboy."
what crap, gen set to elec motor is like 12.% extra loss to start with
So we are saying 200hp to drive a 50 yacht at 9 kts. The gen sets will use half that
Add CPP props and I’l bet the same old big engines meet any DE consumption
Siemans should know they have been sued more then once and had to pay to convert a vessel back to direct drive at least once.
26gph at 12 knots, how would 2 x 3512’s do that?
