I have been keeping up with this group since the first sailrocket, this round I have been checking daily. This boat is a nasty beast, it's built so the foil actually creates cavitation which essentially releases it from the drag and should allow them to leap forward in speed. right now they are pushing 50kts in mid upper 20s wind speed. The science behind this boat is very cool; take the time to read about the design. Right now they are in the 3rd week of the month long period to set the record. Currently they are stuck at a 50kt hump that they can't seem to get over. The foil isn't ventilating like it should and therefore creating too much drag, over the past two days they have chopped 45cm off the bottom of the foil in an attempt to get it to release. Based on the physics of it all, little of which I truly grasp, once it releases then there should be very little limitation on speed up through 60kts! Like I said this thing is insane! It is designed to beat the kiters for the all out speed record!
