You really need to consult with a marine architect for this type of modification. I doubt your insurance company will approve of the modification otherwise, and it would adversely affect your coverage, should any damage occur to the mizzen or aft deck.

Eliminate Compression Post? Calculation of Force
For you structural engineers out there.
Anybody out there have a sense of how hard it would be to remove a mizzen compression post and replace the support function with an arch/box structure and side tie ins? I want the open space.
It is a 56 foot steel ketch and I assume that there is some downward force design load on the mizzen mast that, if met by the arch/box and distributed into the topsides could allow the removal of the post.
