I imagine extending the surface past the centerline would make it easier to find the developable surface, but one would lose control over the exact shape of the stem, as it would be given by the intersection of the surface with a plane.

Remember that you never have perfect control over the exact shape of anything. You are constrained to what the material can achieve. If you could just draw out the chine, keel and stems the way you wanted them and have it work, you would not need to worry about whether the surface will develop.

My CAD package will display rulings for developable surfaces, but while I will look at them, I also look at sectional shapes and surface curvature and make an educated guess as to whether the plywood will be able to form to something resembling what I want. The analysis tools are useful, but experience is the final arbiter.

You can get very thin plywood which is probably the closest analog for scale models because the grain orientation does effect how the material bends.
