If it is a one piece mast it will not work in any sail after about a 1987 - 1990 model.
There's ya problem.
One time I disagree Mark, you may be correct with 90% of masts, But there's a few of us still using our mid 1990s one piece Killwell matrix 5s, 70% carbon constant curve. None of the 30% glass goes up the mast, that's the carbon's job, the glass only goes around. They're slightly reduced diameter (the old windsurfer, tyransea standard), tough as nails and last for ever. All my modern sails designed to rig on constant curve masts set very well on them.
You can recognise me coming by the masts on the roof.
