This is my method for creating the deck of a boat or ship when the deck is based on a master deck section curve. All sections of the deck are a trimmed master deck section curve. All that is needed to begin is the sheer curve (edge of deck) and the master deck section curve, sometimes referred to as a master camber curve. The deck centerline shape is found as part of the process.

Start by creating or copying the master deck section curve at one end of the sheer curve. The curve in the example is a circular arc which is most common, but it can be any shape.
Rotate with Copy=Yes the master deck section curve 180 degrees in end view to create a temporary curve which will be used to find the deck centerline.
ExtrudeAlongCrv the temporary curve along the sheer curve to create a temporary surface.
Intersect the temporary surface and a plane along the center to obtain the centerline of the deck surface. An alternate method would be to project a centerline onto the temporary surface in top view.
ExtrudeAlongCrv the deck master section curve along the sheer curve to create an untrimmed deck surface.
Trim the deck surface with the sheer curve.
