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
Kevin. Glad you weren't hurt! Boats can be fixed. Closest.mast match is a Dwyer DM-6 :: Dave Scobie :: M6'8" #650 :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - www.freewebs.com/m15-named-scred/ On Sat, May 25, 2019, 6:28 PM Kevin Sandwick <ksandwick@hotmail.com> wrote:

Ouch!! Major bummer, sad to hear this. And ditto Dave, glad you are OK, our masts & connected stuff are plenty big to be dangerous when they break. Someone else here recently got a mast from Dwyer and IIRC was sent their hinged base plate instead of the SS tabernacle normally used on Montys...so if you order from them be sure to specify the right step hardware. Best wishes for getting back on the water sooner than later... John On 5/25/19 6:27 PM, Kevin Sandwick wrote:

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.
