How should the sail "power center" (excuse vocabulary) be located compared
to the keel center. In front of, or behind?

It's more complicated that just the keel center.
There is the CE on the sails and the CLR (center of lateral

in front of the LCR and how much is expressed is in % of WL. That % is
named lead and varies in function of the boat, sail plan and mood of
the designer.
OK, experience of the designer.
Plus the CE and LCR change . . .

Any book about yacht design will explain that but my preferred one is
