The Mochi 54 was the first model introduced here and did very well-there are 11 of them plying U.S. waters. The 74 was next and was a tougher sell-its 22-foot beam might have stretched the idea of the lobster boat beyond the practical comfort point of the Yankee imagination. The 44 was Mochi's third model (there's now a 64 in the line, too) and she seems the perfect size in most ways-but don't let her fine looks fool you. It hasn't been the easiest yacht to sell to Americans, confided Da Zara, but he sees that starting to turn around. "It takes a daring customer to depart from a traditional design for something more luxe, sexier, curvier, and bolder. With Rivarama number three," he said, referring to the newer offspring of the venerable Riva marque, a product line he used to oversee, "we couldn't sell that boat for cost. Now, three years later, we sell them all at full retail."
