Need Approach to Bossing

I have worked my way to the back of the shaft bossing where I am a bit stuck. For the last piece I have DUPED on the three meeting points then FILET by 1". Then I have extended to the a semicircle at the end of the shaft bossing.

My question is how to get the three forward edges of the bossing piece to match the aft pieces of the hull? I have one edge that need to match to three edges.

If I could get past that, I could probably figure out a way to fill in the corners.


I would have loved to have done this without the FILLET but Rhino does not like to do a transition to zero radius.
