The introduction of the 57 follows a deliberate path developed by David Marlow, the man behind the curtain. He first introduced the Explorer 65, then expanded the line to include a 61, 70, 72 and 78. (The 78 is scheduled to launch late next year.) Thanks to strong initial interest in the 57, Marlow actually intended to build her before some of the larger models. Marlow's backlog, however, was large enough that it would not make sound fiscal sense to start building the smaller sister. A second factory came on line a year ago, however, allowing the yard to increase production and broaden the variety of products in its range.
