I inherited a Pearson 26 that was dis-masted after the starboard chain plate cracked and yielded. It broke right at the spreaders. The previous owner looked for a matching piece of extrusion for a year and a half before he was transfered and I then looked for another 9 months (through a bad hurricane season as well) with no luck.
I had to improvise and buy an "equivalent" stick - which causes a new set of money issues by needing a new step, hardware, spreaders and mainsail.
Although I have never been in a dis-masting incident, from what I have seen and heard - check your rigging and chain plates regularly. It is too dangerous and expensive to take your standing rigging for granted.
