Personally, I think that the most usefull reading, upwind on a catmaran would be apparant wind speed; keep it as high as possible! I want a very faint audio pitch (in my ear from my sunglasses frame or helmet) in my ear that varies in pitch as the wind varies in speed. ("Electronic Shroud Whistle")
Maybe I'll try fastening a whistle to my forestay's bridle wire. Like one of those deer/elk warning gizmos.
