Those 'struts' look like they could be dragging in the water a fair amount with any sort of heel
I reckon all the brains involved in this project just might have thought about that and little more besides.
"CQS after the start of the Royal Akarana Yacht Club White Island Race. For this Qualifying Race she sailed without the DSS foils which protrude horizontally from her topside and provide lift, reducing hull drag and producing more righting moment. Her movement through the water was very clean, as would be expected of a supermaxi of her size in a flat sea state. The aero-foiled rig supports were occasionally clipping a wave. But the aero-foiling meant that only fine spray was being thrown, and contact with waves when heeled was surprisingly rare - and usually rectified by the helmsman luffing closer to the wind. She is sailing this race using her canting keel only, and daggerboard. With the DSS foils fitting they are expected to generate lift as CQS heels and this should minimise wave strike on the wing supports."
