From the December 2008 Issue of Power & Motoryacht magazine:
The new Jarrett Bay 77 will be a force to be reckoned with. Packing 2,400-hp MTUs, she’s predicted to reach a top speed of 42 knots or nearly 50 mph, downright impressive for a 77-footer that tips the scales at about 60 tons, not counting fuel, water, or provisions. Even throttled back, she should cruise at 37 knots, or better than 42 mph.
