Bob,
As is true of most things, it is easy. When the wood is still in block shape, draw the top centerline on the wood, cement the top plan (punch some holes on the centerline of the plan so the centerline on the wood can be seen).
There are then two location tricks for the bottom centerline, drill a hole (with drill press to keep vertical) or cut on the centerline with a thin scroll saw blade to 1" past the end of the ship at the waterline (a .016" blade leaves a slot that will just take a .020" strip of plastic). Insert the plastic strip which has the bow profile cut so that the length of the strip at the waterline is 1".
I use the strip when there is a pointed end (which was both bow and stern for the Enterprise) and the drill hole for a rounded stern. The strip also is a perfect guide for sanding and keeping the bow or stern vertical (I cannot keep a curved pointed bow vertical without the plastic guide). The location of the hole or slot is put on the plans before they are copied.
The attached photo of a CVL shows the plastic bow guide.
