The GT63 EFB is the largest yacht in Hatteras' high-performance GT series and she offers the sophisticated buyer a lot of advantages that can be found nowhere else. The GT63 comes in two versions, one with an open flying bridge and one enclosed as shown above. That is the model we recently tested. This new design maintains the classic features that have made custom Carolina sportfishermen the benchmark in style and performance for big game anglers. But the Hatteras GT63 has a build that goes beyond what can be found on the Outer Banks. She is both a fighting machine second to none, but also a comfortable cruising yacht with both speed and long legs if need be.
