Could the unknown cat sailor be Fred Metcalf or Micheal Coffman ?

A go fast tip. In very light winds and big wind. Flat is fast with the superwing mast. In both sail with little mastrotation and a really tight downhaul. Mainsheet should be rather slack in the very light stuff (sailing with significant twist) and tight in the big winds. It will feel like you are sailing underpowered but it is actually faster then when sailing with a powered up feel. You must look to get the boat "streaming". Sometimes the required trim for this to happen feels counteractive, like depowering the rig further when you are feeling you are lacking grunt and others are passing you. For some reason you'll feel more underpowered but speed up anyway.

Welcome to wonderous world of wing mast sailing (A-cats, F16's and Capricorn F18)

How are the Datchet boys doing at their trainings weekend. James did you get a test sail on the Stealth F16's, your report ?
