General rule of thumb is 1.5 times the length of the boat for jib/genoa and 2 x for spin sheets.
Your whisker pole should be 90 degrees from the mast for max projection so the same height as your genoa's clew off the deck when sailing down wind is a good starting point. How high the exit on the mast for the halyards is largely dependant on you sailing "style". For example, if you are a racer, you would want the spin halyard to exit the mast about an arms length over your head so your "mast man" could pull the most line with a single "heave". If you are going for the "clean" look and only "work" from the cockpit, the lower the better. The later model Cat 27's with internal halyards had them exiting at the base of the mast. What ever you do, don't have them all exiting at the same height, it will weaken the mast.

I am also installing a whisker pole eye...what is a good height for a single point attachement? I am also converting to internal halyards where (what height from the mast base) should the exit blocks be located? Thanks - Joe
