dweinkauf,
Page 39 and 40 of the H46 owners manual was all the information I had. I did not use the schaefer base/bar, instead I designed a triangle base installed in the bulkhead that also supported the deck. On the deck I used a folding double "D"ring. The scheafer bar is attached to the cabin side of the anchor locker bulkhead. I also installed a second car to both jib sheet tracks for the stay sail sheets.
Good luck,
V49
