Unfortunately I now have an original 1985 J/22 mast that is twisted at the bottom and a new in April 2008 mast broken at the topping lift exit box. I'm thinking of making one good cruising mast between the two carcasses. How long do you think the fabricated internal sleeve should be for this repair? Thanks in advance.
