Yes, she is a Wilderness 1620 (now 1660 with a bit added to the lowest transom step) though to call them "pre-fabricated" is a bit of a stretch. The hull panels
and frames, as well as a lot of the furniture panels
etc, are pre-routed and pre-scarfed Duflex panels that are then joined side to side to make the full lengths.
She is being built by a yard in Xinhui, near Zhuhai - Timeless Yachts, simultaneously with another Schionning boat, a Wilderness 1230.
