It great to see some making efforts on new designs and 20 classes . thanks so much .

Agree Rolf , what surprises me is that we still use the basic Marconi rig configuration developed 100 += years ago .

Why don't we have multihull specific rig configurations using its wide platform and more advanced tech we see in boardsails ie . carbon fibre masts with a huge range of shapes placed on more aft raked adjustable rig configurations .

With the exception of expensive fragile C Class wings there has been relatively little progress .

Wings aren't practical but we can make advances in rig configurations along with foils .

If I could just win the lotto I,d try to develop some ---take care --have fun
