Since the 323's bulkheads are slipped into 'pockets' in the hull liner during construction the bulkheads are not fully tabbed with glass and resin around their entire perimeter like old school construction where the 'furniture' is constructed by cabinet makers after the deck is laid on top of the hull.
The result is when hard on the wind the 323's chainplates 'squeeze' the hull and the result is the coachroof may bulge upward and the bulkheads can move around in their hull liner pockets...
The answer, and it is used on many boats, is to have a tie-rod or some other apparatus that restrains the coachroof connected to the hull and keeps all the deigned shapes correct.
This little rod is important! Its tab on the mast step and corresponding aluminum collar at the mast partners through the coachroof are crucial so you want to keep them ship-shape.
