    Im totally with Gary, its a simple fix with composites if you are willing to think outside the box. Replacement is not always an option due to cost or location. Mast replacement can often cost more than an older boat is worth. We have repaired a very tall bendy mast on an old one tonner which was cracked at the partners caused by the fasteners which held the internal sleeve. This was meant as a temporary fix but its been working well for several years of hard racing and the owner is spending his money on sails instead.

    Btw, we did about 8ft or so from the butt to the gooseneck tapering out at the top,we sandblasted, used a toughened epoxy worked in with a scotchbrite immediatly after blasting, then a layup of uni s-glass, no carbon, and finished with a layer of double bias and then painted of course.

    Chevy truck drive shafts for a 90s model were aluminum with a fiberglass sheathing. The design had shortcomings up here in Maine where (winter road) salt got in and expanded the aluminum which caused the glass to rupture.
    So one should remember what a sloppy job might result in, given the materials are identical.
