I'm still new to sailing, I have a O'Day 25 and am installng a new windex today.I need to bend the reference tabs on my windex before I install. According the the box it tells me to set it at 55 Degrees for boats with "extremely good windward performance" 60 for marginal and 65 "auxilaries and similar type boats."How good is the windward performance for my 25? Any suggestions on where to set it.I know it is not terribly critical and I will have to get a feeling for what works on the boat, but any suggestions on where to start would be appreciated.
