Hi Chris,
Contact you local water sports club / sailing club or shop, it's amazing
how many fibre glass masts there are about as lots of people are turning to
the Carbon Fibre type now they are becoming cheaper, they also get some
damaged ones which you may ba able to cut a piece out from it.
It's worth a try.
