Wing shape and section

• An adjustment of the wing angle to increase the righting moment when sailed at the optimum heel angle.
• Single one-piece beams used for ultimate strength and stiffness, with the fore and aft beam section shape refined to encourage attached flow, and the outer beam now incorporated into the solid tramp.
• A redesign of all connections between beams, tramps, deck.
• A reduction of the planform areas.
• In terms of weight changes, if anything a slight reduction in weight.
