  1. The ensuite head for the portside guest twin stateroom has a very nice touch: that overhead hatch precludes the need to turn on a light switch except at night. And, there is a good source of fresh air if needed. The shower stall is a circular affair with a curved Plexi-door following a track. This has become a popular and efficient use of space.

    Twin Bunk Head...
  2. Hatteras chose 2400hp MTU 16V 2000s for their flagship sportfish. That’s the largest motor currently available. Hatteras conservatively puts the 77's displacement at 157,500 lbs... and that’s with full fuel and water. The captain related to me that at 2150 rpm (they’re rated at 2450), he’s loafing along at 28-29 knots. She’s running about four degrees up here; not too bad. Very impressive, actually.

    Offshore Speed...
  3. Note the double chine which has been a Hatteras standard since forever. The lower chine is about 4” wide and runs from stem to stern providing a great deal of the lift at speed as well as knocking the spray down. Not much keel here. Perhaps at roughly 160,000lbs. displacement, not much is needed. Compare this to the older Hatts with very deep keels. During the speed/horsepower races of the late ‘70s-early ‘80s, Hatteras would cut down the keel of some models and they became ‘Performance’ models. The slightly convex bow of the 77 showing her double chines and two lifting strakes... a far cry from the fine entry of the older models.

    Hull Illustration...
  4. Propeller pockets not only reduce draft, they enable closer to true-zero thrust lines... a significant performance advantage as this reduces the wetted running surface of the hull. Inside the pocket, along the annular, are slots to aerate the boundary layer around the tunnels, creating a surfacing effect for the props and adding a degree of vibration insulation. In yet another example of applied technology, trim tabs are being utilized directly over the pockets for vectored thrust, a powerful way of inducing trim.

    Prop Pockets with Passive Air Induction...
  5. Looking more like a partially ducted impeller, that Nibral wheel is a 49” X 83.5” X 8 blades. The rudders are reported to be quite effective at speed. Hatteras specs call for 5’3” draft. Your intrepid reporter measured 5’4”. One must admire the conservatism of Hatteras’ numbers. Not seen in this image is the underwater exhaust system that vents just forward of the transom (under the hull). This system adds lift coming on plane and helps aerate the trailing portion of the hull at speed.

    Applied Surfacing Principles...
  6. With a resolve to advance the Convertible state-of-the-art, Hatteras has raised the bar considerably. The new 77' is not just a crowning achievement for Hatteras, it confirms their commitment to excellence while setting a precedent for the future.​
