Jerry,
Just tossing something out here on your internal halyard project, probably done already.

Suppose you made those plates into a sleeve box by welding top and bottom shut (except of course where lines lead down inside off the sheeves)
you could place the sheeves more inboard IN the mast. In other words just have the sheeve grooves out far enough to keep lines off the mast.

You could then attach the sleeve with rt angle tabs in the four corners to the mast outside.
Could also close off more of the vertical opening in the sleeve if wanted.
Curve the plates out far enough to protect the sheeves, but radius the plate edges to meet the mast top and bottom.
Less windage
