Broken Mast...Repair or replace

[hemi]

As a general question to the forum, I would like opinion of what my options may be related to a broken mast.

General Information: 52' Cutter, Aluminum mast built in Cape Town South Africa 1990, 3 spreader rig, 3 mast sections, I dimension is roughly 73', Standing rigging 1/2" strand.

What happened: Starboard shroud turnbuckle failed 300 miles offshore in a 35 -45 kt blow. Mast separated fairly clean (+/- 2 inches) within second section above lower spreaders.

Basic question is can a mast section be repaired with sleeving assuming the correct sectional parts can be obtained? Would this approach put an unacceptable amount of weight aloft?

At what point do you scrap the spar and look for a replacement?

I realize that these questions are difficult to answer without more details or photos but will try to provide additional information as requested.
Thanks.
