The optional layout for the 39SX features the same generous salon/helm deck on the main level, including a Stidd® helm seat and corner L-settee. The corner settee in this layout, however, is fully extended to allow for more seating along the port-side windows. It does eliminate the possibility of a companion helm in this layout.

Below deck, the optional layout offers a second stateroom in place of the standard dinette. The forward stateroom, galley and head remain unchanged from the standard arrangement.
