Did crevice corrosion due to electrolysis play any part in weakening your mast at the spreaders? Stainless Steel bolt, tangs, etc. and aluminum contact. Lost a mast on a 20footer once off the coast of Florida. Thank goodness for the "iron jenny". I was out in the Gulf Stream drifting north at about 3 knots, away from my home port.

I had a catastrophic mast failure today. In my analysis I believe there were three factors. 1- Oversized bolt hole at the spreaders 2- Loose inner stays 3- Strong gust in an already brisk wind.
The mast parted right where the spreader bolt goes through the mast. After cleaning up the chaos at the deck I was able to get to shore and survey the carnage. My question at this point is, What is the mast section/profile. Looking at Dwyer Mast there are many to choose from. Is there a particular supplier for Montgomery masts? It is too early in the season to give up the game so I am going to try and get back on the water as soon as I can. Thanks in advance for any information. Kevin Nauti-Cal Hull #400
