JR uses thicker sheets honeycomb (single sculls - 4mm honeycomb, pairs/double sculls - 6mm honeycomb, quads/fours - 8mm honeycomb, Eights - 8mm honeycomb + the vertical web) to improve longitudinal and torsional stiffness.
Using the I-Beam principal, a boat with thicker honeycomb will be stiffer than a boat with thinner honeycomb. What is a vertical web?. Longitudinally from bow to stern and from the bottom of the hull to the underside of the deck is a bulkhead of honeycomb cored carbon fibre. This improves stiffness in our eights by adding an additional triangulation of material under the deck.
