boards on the Taipan arre far back as the V-ed bows runs deep and narrow like a plate, but the aft sections have rounded keel. There is always a play between boards, rudders AND the hull. Rounded keel line on the bow required different board placements. Can 't easily compare board positions on boats with significantly different keel lines.

I shied aways from making complete new daggerboard wells over gaining 0.25 mtr pole length. Sue me !

BTW lots of leehelm is bad under spinnaker as rudders act like a brake then. I know because I tried. My current setup is the fastest without completely rebuilding the hulls or the daggerboard wells.
