C34 Mark II in mast furling mast step cracks
« on: September 16, 2019, 05:45:25 PM »

Just wondering if anyone with in mast furling has had problems with factory mast step cracking. Mine has cracked at both bolt holes. I sent photos to the mast and step manufacturer, and was told the step as manufactured has four bolt holding it in place. Mine has been modified....I assume by Catalina at manufacture. Cut marks are clearly seen on the step itself. Catalina tech rep said he has not heard of any problems on the 34ís. Would be grateful to hear and see what experience and fixes others have had.

Shamrock has a furling main, the step may not be different from the standard mast.  Will check on mine today.  Had my mast down last year and all was good.  Only problem with mine was no drainage at mast to step, after a rain would leak for days on the cabin deck.  When the mast was down I drilled a hole low on the mast, problem fixed.  Would like to see pictures of your mast step crack.
Also suggest you add boat info to signature.  See what others have done.

Yes the in-mast furling is a different setup. I will try to add a pic.

Here are my pictures.  There are 2 through bolts that are inside the mast, fore and aft for a total of 4.  Can see them from the cabin.  As most of the forces are in compression, it wouldn't keep me from sailing.  IMHO  I'd change it when the mast was stepped for other work.

Thanks for posting the pics, Jim. I was thinking the nuts in the cabin top were for the compression post. I can see the crack on one side extends under the mast so I have scheduled to have the mast pulled on Thursday. Will post what is found.
