On the flat water of the inland lakes I sail, when the wind howls its time to sheet in, travel up, drive down and move to the back of the bus. I've run the bow on my 6.0NA down to the foil on a (really) broad reach and never felt like I was going to auger in. However I drive as deep as I can without sailing by the lee, guessing >>135° apparent, which aides in keeping the windward hull down if not just barely out of the water. Gybes are terrifyingly fast when sailing a narrow track. Stopping is a different matter as hitting the beach full bore is bad. More on that when I finally figure out the brakes on this thing. Rounding up into the wind to luff is scary when moving that fast.
