His comment coming back after two hours:
"Some years ago, the concept of the Quant 28 surprized me in many aspects, like performance and simplicity.
Now, the concept was pushed to the extreme, to form a foiling monohull, with again surprizing qualities. The stability of the boat increases dramatically with speed, making foiling safe and easy."
