They are terrific boats. One of the nicest Hatteras Yachts I have ever seen is Lonnie's "Green Eyed Girl", a Series 2 45C which was repowered with M11s at Jarrett Bay. Great layout, great looking boat, and from everything I've ever heard a rocket- 34 kts plus. That's forty miles an hour- how fast does anyone need to go? If I were starting out now looking for a Hatteras SF, I would look no further than the right one of those.
