Welcome aboard, BaladinII.
Cool job on your boat
. And just to clear up any potential confusion, I think you meant to say a 'refurbished' mast
. The word ending en englaise does make a difference!!
And to answer your question, you could start by posting
a "Wanted" ad in this sub forum: http://www.cruisersforum.com/forums/f64/
Remember to include your preferences, such as aluminium or wood. And is the boat 35 feet, or is the mast you want 35 feet?
