Well Downeasts are pretty much always single diesels, but really the question is why do you need to go 44 kts in a Downeast? The hulls really aren't optimal fort that kind of speed, it's gonna be a handful at anywhere near top speed. A sporty with a deeper vee and twins is what I'd want if I wanted to go that fast.
I bet the guy has all of that $650K in it and and maybe more and I'm sure he picked the power but not many people would when you could go with half that hp and weight and cruise all day at 22 kts and burn half the fuel. Plus there's nothing wrong with the finish but it's not a plus, somebody who wanted it for a yacht would be looking at spending a lot of money in upgrades. The boat's kind of a one-off, cool in its way but not something many people would want. imo.
edit: I don't mean to sound like I don't think it's a cool boat, I do. I was just more talking about the price and marketability, for whatever reason that's what I started thinking about.
