  Why not the margins?

The cross-sectional shape of the hull is like half an I-beam (albeit a distorted one) right at the edge of the foam core. If the anchorage point is within the curvature of that junction of the two layers, that nearly-vertical section coming off the edge of the core will be tension, and in an orientation far more effective at providing flexural strength than adding layers to an already-flat section of hull and applying a right-angle force. In addition, the close proximity of the anchor point to the stiffest part of the entire boat seems like an advantage, rather than a disadvantage, since the load applied here would not tend to pull one layer away from the core as could happen if the anchorage were directly over the core. From an engineering standpoint, I don't understand why one would want to avoid this situation.
