We all are seeing what Emirates Team New Zealand did to the AC cup catamarans, showing up for the event with blades that enabled foiling, that sent everyone else back to the drawing board. That certainly got everyone thinking 'why not my boat, too'. Scuttlebutt has this video and article, http://www.sailingscuttlebutt.com/2...9fe321a925da53189&utm_source=Email Newsletter, about some innovative Laser daggerboard and rudder that could promote foiling. So why not a Sunfish version? We have a lot of creative and capable contributors here. Is there a do it yourself Sunfish upgrade we could come up with? Even if the boat doesn't totally fly in most circumstances, it would seem that properly designed lifting foils could seriously promote planing. This seems like too good of a breakthrough to not at least try!
