G'day Rolf we had Greg Wise on a Foiling Moth come here last January for our 15km downhill run from Cape Jaffa. The F18 crossed the start line with spin but not enough wind for the Moth he sat in the water long after I was gone then flashed by at much wider angles than us but unbelievably fast. The wind came up and he caught the leaders at the rounding mark but then the wind dropped out and he went slow up hill so he came 3rd. These photo's show the sequence, the moths in the water as they cross the line in the first photo. The whole fleet's gone in the 2nd and he's caught them at the rounding mark but no longer foiling in the third. As soon as there was enough wind for the spin guys to get on the wire the moth went unbelievably fast. Most of us at the club want to try one.
Notice the F18 is not even in the second photo it was long gone
