Uphill on the H-20, pretty much tack when the mark is at 2:34 or 9:15, not quite square to the beam but close.

Downhill.. .it's ALL about feel. Light-Med is the toughest once it's breezier it sucks for the crew (as me how I know) but the feel is MUCH easier. 15+ I'd say your windward hull should be 3/4 out of the water with just the area around the dagger kissing. Make sure to keep your weight forward on that boat till you get to say 12-15.
