Kevin. Tangs need to move or you are likely to bend the upper swage fittings on the shrouds as you raise/lower the mast. If the mast folded at the spreaders wondering about the mast wall being dimpled from prior damage or to much tightening of the bolt securing the spreaders. Did the bolt have a compression post? Incorrect tuning is also a possibility. If the mast got out of line of itself - fold away. So few of Jerry's rigs have failed, excluding hitting trees, I'd not think the hardware installation is the cause of the accident. :: 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 Sun, May 26, 2019, 2:15 PM Kevin Sandwick <ksandwick@hotmail.com> wrote:
Re-Mast Failure, Thanks for the information, Will be calling Dwyer on Tuesday, Any thoughts on using SS tangs riveted to the mast as opposed the original hole and bolt method? Thanks again, Kevin ________________________________ Kevin.
Glad you weren't hurt! Boats can be fixed.
Closest mast match is a Dwyer DM-6

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
