Canyon 456
45' CENTER CONSOLE
Re-imagine the luxury sportfishing yacht. Grady-White’s new flagship, the Canyon 456 center console, is incredibly spacious, technically sophisticated, and more richly appointed than any other outboard sportfishing boat. The 456 Grady is crafted with exceptional attention to detail and is superbly engineered for an entirely new level of elegance. It has by far the widest beam in the category and is also the largest unsinkable boat of its kind.
