WHere did you see that? Is that actual performance and is that with the optional 750gls of fuel? Only specs I've seen are the estimated performance specs that are also posted in this thread. That spec sheet seems nearly identical to the original 70C which would give you around 360NM range at 28kt burning 150gph. That's with the 1800hp 16V2000s and the same 2000gls of fuel. Hatteras typically offers more fuel and extended range but I guess that's hard to do with engines this big and this thirsty. Keep in mind these engines are massive. They're about 2200ci and nearly 9K lbs. My neighbor has the 2435hp version of them in his 90ft Pershing and his fuel burn is similar with the posted spec sheet. He carries 2500gls and says he needs to stop for fuel about every 300-350NM. He does like to run the boat at a fast cruise and sometimes on the pins for extended periods.
