the foam core or its margins. An exception might be made if a tie point is only going to serve light duty.
It is possible to spread the stress of a tie point by incorporating a base of two concentric round or oval layers of Kevlar. The largest layer would be first on the hull. Even a single layer would help. Kevlar is a very light cloth and so won't add as much weight.
