While they don't require a bulkhead they do require a solid attachment point. A knee glassed in under the deck would work. but I would see if there is already a bulkhead or some other solid point near the desired point of attachment. If so it might make sense to alter the location a bit and use something already available. If not you will have to create one. I would probably make it 10" or so deep and well glassed (with epoxy) to the hull to spread the load as much as possible. Try and align it with the angle of the runner. Use multiple layers of glass (biaxial is best) and make each successive layer bigger in area than the last.
