Rod, I also installed a whisker pole track on the front of the mast with no problem as far as the conduit is concerned. I tapped dead-center and used 1/4 X 20 SS machine bolts that were 3/4 long. Don't forget to use Tef-gel to avoid dissimilar metal corrosion between the bolts and the mast.. Paul Weikel Second Chance #361 Georgetown, MD
