The Moth Dinghy developed foiling to near perfection through two decades of information sharing and weekly racing amongst an international group of backyard tinkerers. The Moth will lift up in 4 knots of wind, once up it can sustain flight in two knots. Meanwhile the America’s Cup boats cancel racing in 10 knots of wind because they know their boats are boring below that speed. This also means the America’s Cup boats cannot really improve foiling performance to be full range. Weekly racing in all conditions is the key.
