If you are judging by top speed only, my vote is for Callen.
But I think that the reliability should be a factor in all of these piston powered boats. Sure they all run fast for the first 10 hours. Or maybe even the 75 hours (doubt full) as the warranty suggest. But these turbines just run and run and run! Your only worries are drives. Turbine are much more easy on drives to begin with, smooth constant power flow.
Extreme Exhibit came up to the thousand islands poker run last summer, wanted to get beside My Way. He did, wasn't as fast and then broke!
My Way didn't finish a poker run up hear till it was turbined!
So if speed is the only judging factor in this thread, fine. But I think the boats mentioned above, and to be mentioned, should be finishing the races the start. And that be taken into consideration.
Can the speed be done in bursts, or all day long?
