Rockport Marine built three W-46 designs—EQUUS, ARION and ZEBRA. They are the smaller version their W-class, 76-foot older sisters, WHITE WINGS and WILD HORSES, designed by the late Joel White. The W-46s were designed by Bob Stephens of Stephens, Waring and White Yacht Design, and are built of wood and composite materials, and outfitted with a light and strong carbon fiber spar.

Below decks is elegantly appointed, with custom cabinetry and interior joinery made of cherry. This makes the boat suitable for racing or cruising, and can be sailed with a crew, or a couple or family.
